GlobalSat BR 355S4 GPS Receiver Black Review

GlobalSat does not provide NMEA cable codes or pin numbers used for I/O/Power and Ground. This information is not provided with the device and GlobalSat does not answer questions about it. Obviously, the device is only designed to be connected to a computer. I cannot comment on the performance of the device as there has been no response from tech support since my purchase on January 7th, 2019.

I bought this to connect directly to my Kenwood TM-700A VHF/UHF Cellular Radio. The radio has built-in APRS and requires GPS to function properly in mobile mode. I tried several other GPS receivers and none worked. The TM-700A requires a serial GPS device and this GPS works! I made a junction box that converts 6 pin DIN to RS-232 DB9 and allows me to connect 5V DC using a 5V DC converter. After plugging in and setting the radio to 4800 baud the GPS came up and quickly blocked.

I used the BR-355S4 to input GPS data into my DSC marine VHF radio (Uniden Solara DSC). The addition of GPS to the radio's DSC capability allows the automatic transmission of longitude and latitude along with the distress call (rather than verbally). 12 VDC to +5 VDC converter module), black to ground, green to GPS NMEA radio input, and white to ground. GPS data acquisition is very fast, typically within 5-10 seconds.

It is important to understand that the pinout in the manual is completely wrong. Correct contacts: 1 - 5 V DC. Power +2 - Ground and VDC. to your computer. via the USB port. 5 VDC can be supplied through your computer's USB port. For marine applications the output must be connected to the serial port as follows: pin 5 - ground - to the BR 355 SR (pin 2) and to the autopilot; Pin 3 - data input - from BR 355 SR (pin 6); Pin 2 - data - to your autopilot

This is a device that Uniden has rebranded as a GPS kit and is fully interchangeable with the Uniden GPS washer, including a 6 pin DIN connector. It has good sensitivity and easily picks up a usable signal. in my basement. It outputs industry standard NMEA RS-232 serial data at 4800 baud. The LED lights constantly when searching for satellites and flashes when it is fixed. If you need to install your own connector, here is the wiring diagram: Black / Shield = Ground Red = +5V (requires around…

Update: 3 stars overall for erratic output and cost. Soldering and cables do not guarantee a 3x increase in the price of bare-clone modules, especially with the unstable output signal below. Fixed cold start in less than 2 minutes but requires level conversion, the output is not ttl it's RS232 which is inverted and the voltage on mine is -4.5v to +7.7v. Added converter but then was able to not be remedied. There are 12 ships in sight but RMC status is V (nav rcvr warning). When power is…

I bought a GlobalSat BR-355S4 (the one with the PS/2 connector, not the one with the USB connector) to connect the GPS input of the Uniden UM385 VHF Marine to provide transceivers. It worked great and only required three wires to connect, although you do need to provide a separate 5V DC power supply. The attached image shows the radio with "GPS Data OK" along with pinout information for both modules. Connect GlobalSat Pin5 TX to the yellow Uniden: NMEA_IN+. grounding Connect the GlobalSat Pin2…
