All those weird ports on the back of the scanner

Posted on by

Modern scanners have a plethora of various ports, jacks and sockets on them. Here is a look at some of them.

Taking a look at the rear panel of the BCD536HP scanner there are 6 different ports on it. From left to right they are:

  • BNC antenna jack
  • External Speaker Jack
  • USB Port (used for WiFi unit only on the 536)
  • GPS Serial Port
  • 3-pin power port
  • Coaxial power port

Other common ports on scanners include:

  • USB programming port
  • Record jack
  • Headphone jack
  • Various serial ports.

Let’s look at each port and what it is used for: (*Bonus! See below for an explanation of the weird hole smack in the middle…)

Antenna Jack:  Of course this is used to connect an antenna to the radio. Most scanners these days use BNC, the little push and turn job you see in the picture. Some handled scanners use the smaller SMA connector. Some older scanners had Motorola or even SO139 connectors and some had both an external connector and an internal threaded connector with a hole in the case to insert it.

External Speaker:  These are used to plug in an external speaker and are different than headphone jacks. Speaker Jacks do not limit the volume like a headphone jack will. When you plug in a speaker into the external speaker jack the inside speaker is disconnected.

Headphone Jack:  The Headphone jack has a limiting circuit to protect from overly loud sound that can damage your hearing. Otherwise it works much like the external speaker jack. Headphone jacks are usually in the front panel of desktop scanners while speaker jacks are usually on the rear. Handheld scanners usually just have a headphone jack on the top.

Record Jack:  The Record Jack allows one to pull audio from the scanner at a constant level that is not affected by the volume control. This is important when the radio is used as a source for recording or streaming. Some older RadioShack scanners and some current Uniden scanners have record jacks.

GPS Serial Port:  Unique to Uniden scanners, the DB-9 Serial port (male) is used mostly to connect a GPS receiver to allow location based scanning. It can also be used to program or control the scanner with the properly constructed cables. Do not confuse this with the female DB-9 port used for programming on older scanners like the BC780XLT or the BC898T

USB Programming port:  Most scanners these days use a USB-Mini port on the front or side to program and control the scanner. On many handheld scanners these ports are also used to charge the batteries and power the radio. On the BCD325P2 a special cable is used to connect a GPS to this port.

Other serial ports:  Some older scanners use different type serial ports. Older Unidens (like the “XT” series) use a unique 4-pin square connector for programming and connection of the RH-96 remote head. HP-1 and HP-2 scanners use that same port style for connecting to a GPS. Older design RadioShack/GRE/Whistler scanners use a jack that is just like a headphone jack for serial port connections.

Coaxial Power Port:  Most desktop/mobile scanners have a coaxial power port to provide 12 VDC to the scanner. There are 2 different jacks in common use. The majority of Uniden mobile and desktop scanners use a “Type M” male jack while most recent RadioShack, GRE and Whistler mobiles use a “Type T” female jack. Both use center-pin positive. Some older handheld scanners use smaller coaxial power ports but newer portable scanners usually use the USB port for charging and external power.

3-pin power port:  This is another unique to Uniden port, similar to the power port used on some of their CB products. On Uniden scanners there are the regular black and red wires for power and a third orange wire used to control the brightness of the display when connected to the lighting circuits of the car.

Discriminator Jack:  This is probably the most popular jack that doesn’t come on scanners. Discriminator audio is used to provide an unfiltered audio source mostly for data decoding. This type of decoding usually does not work from the record or speaker jacks due to the filtering circuitry in the radio. Scanners usually do not come with jacks for this but it is often added on by advanced scanner hobbyists to allow data decoding.

 

Bonus Round

See that threaded hole smack in the middle of the back panel in the picture at the top of the page? Most Uniden base/mobile scanners have that. It is used to allow a rear bracket to stabilize the radio under the dashboard. It is not mentioned in the owner’s manuals but is shown in the diagrams.

WiFi on BCD536HP. How does it work?  What you can and can’t do with it.

Posted on by

The Uniden Bearcat BCD536HP is the only scanner that has the capability of being directly controlled by WiFi. By using the included WiFi dongle one can connect a smart phone or tablet to the scanner and listen to and control the scanner with the device. There are some other uses for the WiFi dongle as well.

Uniden has provided free “Siren” software (available for free via the Apple iTunes store or Google Play Store) to allow you to use your smart device as a scanner controller. You can even use this as a remote head for the scanner if mounted in a vehicle or to listen to your scanner from the patio or another room of the house for a scanner installed in the home. Some third party software allows you to use the WiFi feature to connect the canner to the computer without the need to plug in a cable.

There are a few things that the WiFi dongle will not work for, this includes database and firmware updates and other programming.

The Wifi dongle is designed specifically to work with your home or office WiFi network. While we have read of people using it for remote access this requires such networking tools as VPN, if you know how that works you probably can figure it out. Sorry, we cannot help with notworking issues like this!

To use the WiFi feature you need to understand the two modes involved; Infrastructure and Access Point.

Infrastructure Mode allows your scanner to connect to your home or office WiFi. This then allows you to connect to the scanner via third-party software like ProScan or RadioFeed or to the Siren application.

To get to Infrastructure Mode use the following steps:

Press Menu then select WiFi Setup>Select WiFI Mode>Infrastructure Mode

The radio will look for local access points and list them. When it displays the list select your router’s SSID name.

Then enter your password for the WiFi access point. This is the same password you would use for setting up any other WiFi device on your network. To enter the password you scroll thru the letters and use the 4 and 6 buttons to move the curser.

Access Point Mode allows you to connect you scanner to a smart phone or tablet (iOS or Android) using the free Siren software. You would use this when you are not in range of your WiFi system, such as when the radio is mounted in a vehicle. This allows you to use a phone or tablet as sort of a remote control head for the scanner.

In Access Point Mode the 536 acts as an Access Point and provides an SSID which you can change or leave at the default. You then connect your phone or tablet to that WiFi SSID and enter in the IP address in the Settings of the device. The IP address can be found in the WiFi settings on the scanner.

Siren is the free app available at the Apple iTunes Store for iPhones, iPads and iPod Touch’s. It is also available for Android devices at the Google Play Store.

Siren is a neat way to use your 536 scanner but there are limits to it. It will only work with the 536, and it has limited abilities for control. It can set the range, select Quick Keys, set the squelch and start and reply the recording features but that is pretty much all she wrote. There is also a 2-3 second delay in hearing the audio compared to the radio itself.

The WiFi feature on the 546 is unique and useful as long as you know its limits.

The BearTracker 885: Is it a scanner or not?

Posted on by

BearTracker885
Uniden recently released its new BearTracker 885 CB-Scanner combination. Here are a few things to know about it:

1) It has a LIMITED FUNCTION scanner.

The 885 has a specially designed scanner built in that will receive local police, fire, EMS and Highway Department channels based on your location. The radio will tell you whether the channel is Police, Fire etc. but it does not indicate the agency or channel name. You can hear the traffic, the display will tell you that it is police or whatever, but it won’t tell you whether it is Mayberry or the Highway Patrol.

2) You can UPDATE but not program the scanner part.

The 885 has a free software program that simply updates the database the radio uses to hear local traffic. You cannot add/delete or modify channels. To update the radio is fairly simple, take out the full-size SD card, insert it into an SD-Card reader attached to your computer and run the updater program. (The radio does not come with an SD-Card reader, if your computer doesn’t have one you can get them for a few dollars.) The updater software pulls the latest data from the RadioReference database and loads it onto the SD-Card. The database is updated weekly but you only need to bother updating the database once or twice a year.

3) How does the 885 know where I am?

The 885 comes with a GPS receiver. The small receiver is connected to the GPS by an included cable, just put the little box in view of the sky (on the dashboard etc.) and plug it in. If this won’t work for you then you can manually enter in the location from the front panel controls of the radio. When using the GPS the radio’s location is updated regularly and the scanner part will reload itself with the local channels.

4) What about the CB?

The 885 is a basic 40 channel CB. It does not do SSB but it has the typical CB features needed to communicate or listen to other vehicles so equipped. It can also be used as a PA (PA Speaker not included) or as a weather receiver.

5) Is it legal?

We are not lawyers and do not offer legal advice. That said, CB’s are legal for use in the USA and Canada without a license. As far as the scanner goes check with your state and local authorities about whether a scanner is allowed in a vehicle. Laws may vary for commercial vehicles. Since this device has no radar detector it is not prohibited from commercial vehicles for that reason.

If you are interested in scanning specific agencies or want a scanner that allows you more choice then perhaps the 885 is not the radio for you. If you are looking for a CB and like the idea of hearing local emergency scanner traffic then this radio could be ideal.

DMR, ProVoice and Ultimate Self Updating

Posted on by

Most people who want the various paid updates for Uniden scanners (DMR, ProVoice or Ultimate Updates) have our staff add the updates to the radios when they buy it. It is simpler and worth the little bit of added expense for a lot of these folks.

There are times when it is not convenient for one to have us do these updates at the time of purchase. Maybe you bought the radio elsewhere (shame on you!) or didn’t know you needed the update until later. Perhaps the target you want to listen to changed to a new system.

You can send the radio to us using the regular Mail In Programming Order Form and have us do the update for you. We can do the updates with or without the programming services.

If you cannot send the radio to us for the updates you can get them directly from Uniden.com. If you live outside the USA or Canada however then Uniden cannot process your credit card for payment. We can!

The first thing you MUST do is to update the firmware to the latest version. On each radio except the 996 and 325P2 it is done thru Sentinel. For users of the 325 and 996P2 you download it from Uniden’s website and run the updater.

After you update the firmware call us and provide the below information and we will then email you with the one-time code to unlock the feature set on your radio.

Model (HomePatrol 1, Home Patrol 2, BCD436HP, BCD536HP, BCD325P2, BCD996P2)

Electronic Serial Number (Not the one on the label!)

HP1, HP2: Press Menu>Advanced, scroll down then press Version Information

All others: Press Menu>Settings>See Scanner Info> Firmware Version

Sum Code (HP1 and HP2 it is the 3 digits right of the dash after the ESN)

Of course will need your email address to send you the code as well as the proper billing address and credit card information.

Once you get the code from us go to the Update menu on the radio and enter it via the keypad. Once the code is entered it remains on the radio forever, you cannot erase it or transfer it to another radio. On the 325, 996, 436 and 536 scanners you can have either or both of the DMR and ProVoice updates. The HP1 and HP2 only support the Ultimate Update.

If you have questions on these updates you can call our scanner experts at 1-800-SCANNER.

Force Write full Database (HP1, HP2 BCD436 and BCD536)

Posted on by

When updating a HP series (HomePatrol 1 and 2, BCD436HP and BCD536HP) scanner one of the update is the database that the ZIP Code feature relies on. If the database has old or incorrect data then it can affect whether you will be able to hear your target. If you update the database on a regular basis you can help ensure that you will hear what you want.

When you update the database within Sentinel (the free software provided by Uniden to support these scanners) it doesn’t actually update the database on the scanner itself. You have to “Force-Write” the database to the scanner. This is easy; after you “Update Master HPDB” in the Update menu just click the “Force-Write Full Database” button on the Write to Scanner (or Write to HomePatrol) item in the Scanner (or HomePatrol) menu.

This ensures that the Master HomePatrol database on your scanner is up to date.

Update the firmware on your scanner!

Posted on by

Why would you want to update the firmware on your scanner, and how do you do it?
First, let’s explain WHAT firmware is. Firmware is the operating system of your radio, it works behind the scenes and tells the radio how to deal with things like keyboard inputs, frequencies, etc. Just like your computer or phone has an operating system (Like Windows 10, iOS etc.) scanners do too. Remember, scanners these days are miniature computers; they work much in the same way.

Firmware updates are released for a couple reasons. They either fix a problem or add/change features. Sometimes they do both. As an example, the BCD436HP’s most recent firmware update added the ability to add ProVoice and DMR digital protocols, before that firmware updates addressed an issue with clock settings.

When updating firmware one must follow ALL instructions CAREFULLY! You have the possibility of “bricking” your radio if you don’t do it right. This means that your $500 scanner may now be more useful as a brick than a radio… Follow the provided instructions to the letter and make sure that the program and firmware file you use is intended for your radio. The firmware for the PRO106 will not work on the WS1040!

Before trying to update the firmware on your radio make sure you have properly downloaded the firmware file itself as well as the installation program (if needed) BEFORE you start. If you do not have a replacement firmware file to install do not start the process since this erases the existing firmware to make the radio ready for the new version. No new version means no radio once you get going.

Some radios firmware updates are easier than others. The HomePatrol type radios use a program called Sentinel to check for new firmware versions and install them (easy, safe). Other Uniden scanners use a “Bearcat Version Updater” program to install a new update. GRE/RadioShack/Whistler scanners also use an application to install new firmware versions (nerve-wracking maybe).

What they all have in common is that they require a computer running Windows to update. (You can do it with a Mac running Windows with Parallels, Fusion, Bootcamp etc.) You also need the appropriate cable to connect from your computer to the radio. This is usually done via USB but some older radios use a Serial port.

Before updating your firmware make sure you have the following on hand:
• The radio you want to update
• The proper cable for your radio, along with the drivers already installed (if needed)
• The Firmware Updating program appropriate for your radio
• The actual firmware file itself (Imperative!)
• A strong sedative or plenty of alcohol to calm your nerves (optional)

Follow the instructions included with the firmware update TO THE LETTER. Make sure your radio and the computer can communicate properly. If you have programming software for your radio then read it first and save the programming file just in case you need to restore it to the radio. This also ensures that the radio and computer can communicate.

We also suggest that you check the RadioReference forum for your radio to see what other people’s experiences have been. Reading about someone else’s mistake is a lot easier than trying to fix your own.

Owners of PRO651 and PRO652 scanners that had tried to update their radios’ firmware versions had issues since no firmware updates were available until recently. Now one can download them and install them so previously bricked radios can be reincarnated.

ScannerMaster can update the firmware on many different models of scanners. Download the Hometown Programming Form for your radio and check the Firmware Update option if you would prefer our expert programmers to do this for you. We keep them heavily sedated all of the time already so their nerves are steady. Firmware Updates for “Zip Code Scanners” (HomePatrol, 436/536 and the TRX/WS1080/1088/1095/1098 series scanners) is included with the Setup and Optimize package already, it is an extra cost option for other scanners. If you aren’t sure call us and we will let you know.

DMR, ProVoice and Ultimate Updates for Uniden Scanners.

Posted on by

ScannerMaster offers a service to install the various paid updates for Uniden HomePatrol, x36 and P2 series scanners. These updates include the HomePatrol Ultimate Update (for HomePatrol 1 and 2 scanners) as well as the ProVoice and DMR/TRBO updates for the BCD436HP, BCD536HP, BCD996P2 and BCD325P2 scanners.

If you buy one of these scanners from ScannerMaster we offer a service to install these options for you before we ship the scanner. You can also send the scanner to us to perform the update, we then send the radio back to you.

Sometimes however it is not practical to send the radio to us. For US and Canadian customers it is pretty simple to buy the update directly from Uniden and install it yourself. For customers in other countries however it is a different story. Uniden can only accept credit cards from US and Canadian addresses. If you live in other countries then Uniden cannot accept your credit card for payment for these updates. They will refer you to a third party like ScannerMaster to obtain your updates.

ScannerMaster can accept credit cards from most countries. As long as the card works on our payment system we can provide you with the secret code to unlock the update for your radio. There are a couple things you will need to do to make this all work out:

First you need to update the FIRMWARE for your scanner. This is so important that if you don’t do it the paid updates just will not work! On the HomePatrol and x36 scanners it is done thru the Sentinel software, on the 325 and 996P2 radios it is done thru a separate (free) program available from Uniden’s website.

Once you have done the Firmware Updates then you need to obtain the “ESN” (Electronic Serial Number” from your scanner along with the “SUM” code. Here are the procedures for this:

HomePatrol-1 and HomePatrol-2:

  • Press Menu
  • Press Advanced Menu
  • Press the down arrow to get to the second page of items
  • Press the Version Information Button.

The ESN is listed and starts with 36 for the HP-1 and 37 for the HP-2. The SUM Code is the last 3 digits past the second dash. The ESN will look something like 36327-0040012345-123, the SUM code is the “123” part.

BCD436HP, BCD536HP, BCD325Ps and BCD996P2:

  • Press Menu
  • Select Settings.
  • (If you do NOT see “Upgrade” as an item in the list go back and update the firmware and start over!)
  • Select See Scanner Information
  • Select Firmware Version
  • The ESN will be listed as “SN37……”
  • The SUM Code will be a 3-digit letter/number combination.
  • We need both the ESN and the SUM Code. Don’t worry about the M-VER code.

We need the complete ESN and the SUM Code as well as the model of radio you have. With this info we can obtain the one-time code that unlocks the feature you want and send that code to you. You then go to the Upgrade menu on your scanner and enter it using the rotary knob to select the numbers. Once the code is properly added the radio will think it over for a minute or so and then announce that it was successful.

Once properly updated the code will stay working on the radio and will not need to be reinstalled. The code will only work for the radio it was obtained and if you dispose of the radio there is no way to transfer the code or feature to another radio.

GPS Based Scanning Tips

Posted on by

Several Uniden scanners support GPS based scanning. There are two main ways this works; Database based and Programming Based.

Scanners that support ZIP Code based programming (The HomePatrol and x36 types) can support GPS in both ways. Scanners that do not have the ZIP Code feature only support Programming based GPS.

ZIP Code based GPS scanning allows the radio to reload itself with the local frequencies based on locations provided by the attached GPS receiver. Instead of pulling over to change the ZIP code every once in awhile the GPS receiver sends the location to the scanner and it will update the location on a regular basis and reload the channels for that area.

Since these use the RadioReference database to provide the information, the GPS centers and ranges are set in the database and included when you update the scanner’s database in Sentinel.

Programming based GPS scanning requires that the Systems, Sites and Groups (or Favorites Lists) be programmed with GPS coordinates and ranges. The GPS sends the location to the radio and when the radio determines that you are within the circle drawn based on the location and range it turns on that item. When you leave the circle it turns it off.

If you use your scanner over a wide area a GPS can allow you to automatically turn on and off systems, sites, groups and/or Favorites Lists automatically and without having to punch in a ZIP Code all the time. If you only use the scanner at home or around a small area a GPS wouldn’t help you but if you travel a lot (RV folk, truckers etc.) it can be invaluable.

Most people use the Uniden GPS receiver with their scanners. It works on all Bearcat GPS-aware scanners without needing to configure it. If you want to use another GPS it has to support the older Serial format and the baud rate settings must be set to match that of the scanner. Most GPS receivers these days (Garmin, TomTom etc.) do not support Serial mode so you will likely be better off with the Uniden GPS.

Scanners that support GPS Scanning:

Sentinel, Sentinel: What’s the difference?

Posted on by

Owners of Uniden ZIP Code scanners can use the free Sentinel software to do database and firmware updates as well as create and edit Favorites Lists. While they look and feel very much the same, the versions of Sentinel for the HomePatrols is different than that for the BCD436HP and BCD536HP.

The HomePatrol Sentinel works for both the original HomePatrol 1 and the newer HomePatrol 2. When installed on your Windows computer it will have a brown shield icon on the desktop.

The BCDx36HP Sentinel works for both the BCD436HP handheld and the BCD536HP desktop/mobile scanners and has a green shield icon on the desktop.

You can easily share Favorites Lists between HP-1’s and HP-2’s as well as between 436’s and 536’s. In order to share Favorites Lists between HomePatrol’s and “x36’s” you need to export from one and import it to the other.

If you have both types of radios you will need to install both versions of Sentinel. Even though they look and feel the same they cannot handle the other radio types. There is no additional learning curve but there are a few terminology differences. For example, in the HomePatrol Sentinel the menu used to read or write to the radio is called “HomePatrol” while the x36 version it is “Scanner”.
