GlobalSat BR-355S4 GPS Receiver (Black)

I am using this for an older Icom ID-880 to do APRS. It works well. You will need to figure out a way to get it +5v, but that's pretty easy. The wiring information is confusing, but it's not entirely their fault. You have to look carefully at the different pin numbers and positions for male and female 6 pin mini din connectors. I wired mine this way for the ID-880 (see picture). I had an old PS2 keyboard extension cable which I cut the male end off of. You could also buy one and do the same. I used the female end and the bare wires.Pin 1 of din to sleeve of 2.5mm stereo plug and to ground of power supplyPin 2 of din to +5vPin 3 of din not connectedPin 4 of din (TX) to ring of 2.5mm stereo plugPin 5 of din (RX) to tip of 2.5mm Stereo plugPin 6 of din not connectedThere aren't that many ID-880s out there anymore, but maybe thsi will help someone, even if you have a different application, maybe the pinouts are helpful. I'm guessing most devices have built in GPS or will need the USB version which will make all this pinout stuff go away. But if anyone is looking to hook some old gear up I hope they stumble on this.

Going on a road trip, and this "build your own bundle" was perfect. The Uniden SDS100 scanner can automatically scan based on GPS location, but I didn't want to shell out $80+ for the Uniden OEM kit that comes with extra cables I would never use. The Uniden OEM kit contains the same GPS unit and comes with a car cigarette lighter adapter.The GPS puck is roughly 2 inches round, PS/2 interface, and has a built-in magnet with a rubber ring to mount on a car body. It also comes with a suction cup for window placement. There is a small red LED status light on the left side of the puck near the cable that gives you statuses:LED Off: No Power, unit is OFF.LED Solid Red: No positional fix, searching for GPS signals.LED Blinking: Position fix established and GPS signals are being received.Buy this GPS unit, and the Uniden BC-UTGC GPS USB Cable (ASIN B07JQFHLBL). Set your SDS100's GPS Baud Rate to 4800, Location Format to DMS, and range to 20 miles, and make sure to turn on the Full Database. To test, enter a zip code that is in another state (easy to remember: 90210), and then plug in the cable. After a little bit, when the GPS updates, the location will change. Make sure to set/change your services so you aren't wasting unnecessary cycles scanning things.

I bought GlobalSat BR-355S4 (the one with the PS/2 connector, not the one with the USB plug) to provide GPS input to a Uniden UM385 VHF Marine Transceiver. It worked beautifully, and requires only connecting three wires, though you need to provide a separate 5VDC power source. The attached picture shows the radio showing "GPS Data OK" on the radio, along with the pinout information for both modules.Attach GlobalSat Pin5 TX to Uniden Yellow: NMEA_IN+.Attach GlobalSat Pin1 GND to Uniden Green: NMEA_IN- and also to a 5V ground.Attach GlobalSat Pin2 VCC to +5V powerFor my 5V power source, I used a 12V cigarette plug USB charger; you'll find 5V across the center two conductors. (Google USB pinout.) Check your junk drawer; you probably have something with a USB plug. Just plug it into the cigarette charger, snip off the other end and then find the two wires with 5V on them, using a volt meter.There is more info on the GPS unit on GlobalSat's website, tho' you can probably do all you need to from the picture here.If you can read simple pinout diagrams and can solder wires, you can do this.I was delighted at how quickly this came together. With one button push, the radio now displays lat, lon, course and speed in knots. Pretty slick.

This is the unit Uniden rebadges for its GPS kit, and is completely interchangeable with the Uniden GPS puck, including the 6-pin DIN connector.It has good sensitivity, and has no trouble picking up a usable signal in my basement. It outputs industry standard 4800baud NMEA RS-232 serial data. The LED lights constantly when searching for satellites, and blinks once it has acquired a fix.If you need to intall your own connector, here's the wiring diagram:Black/Shield = GroundRed = +5V (requires about 50mA)Green = RS232 GPS Data OutWhite = RS232 Data In (only used to configure the GPS, not needed for most applications)

Works as needed, but connection does not hold needs to be taped together to stay connected.

GPS did not work with my marine radio. The pins were different and it was advertised as it would work. Drilled holes in my navstation and wired it only find out I couldn’t plug it in. Very disappointing ~

works as expected

I bought this to connect directly to my Kenwood TM-700A VHF/UHF mobile radio. The radio has built-in APRS and requires a GPS to function properly when mobile. I tried several other GPS receivers, and none of them worked. The TM-700A requires a serial GPS device and this GPS worked! I made a connector box that converts the 6 PIN DIn to RS-232 DB9 and allows me to plug in 5V DC using a DC-DC 5v converter. Once plugged in and the radio set to 4800 baud, the GPS came up and locked quickly.
