SDS100/SDS200: Handheld GPS direct connect to SDS100

[wilkie647hm]

I have a Garmin GPSMAP 64s handheld unit that has nema output via USB mini connection. Can this be used by hooking directly to the sds100? I have a USB 2.0 mini male to male that will connect the radio directly to the gps. GPS has its own power source and does output nema 4800 baud rate.

Probably - I used a GPS60 for a few years. Does it have any other output than the USB? On my 60 you had to use the 4 pole plug - It says it's NMEA 0183 compatible. FWIW - no idea on the exact method.
You will lprobably need this

Easier and cheaper to buy a separate GPS

The SDS100 only has USB ports.

Update:
1. I have tried USB mini direct from GPS to SDS100 set at 4800 baud.... no good.
2. I tried USB mini from GPS to standard USB with converter attachment down to USB port on radio, no good.
Both GPS and radio set to 4800 baud, same coordinates format, GPS output is 5 volts.

Any other suggestions?

The GPS port on the SDS100 use a serial RS232 signalling and not USB. You would have to go into your GPS receiver and take out a serial data signal and then feed that to the scanners GPS port.

SDS100/SDS200: - SDS200 using R8 radar detector GPS?

Does anyone know or have experience using the Uniden R8 radar detector as GPS source for SDS scanners? It would be nice if it does work just to keep more clutter off the dash.

As I said before - you will not get NMEA out of the 64 via USB. You will need this Serial Data/Power Cable | Garmin and roll your own cable into the USB,

I don't know what are inside of that cable Phask refers to, besides a voltage regulator down to 5 volt to power the Garmin. Perhaps it also has some sort of data converting function. You should really use a computer and see what data that are sent straight out of the GPS without a special Garmin cable converter. You can easily set a serial data mode, 4800,8 no parity nor stop bit, in a command window to look at the data from a comport. Some computers do not have a serial RS232 data port but then you can use a serial to USB converter cable.

A Uniden scanner probably only detects the GPS data and not the Glonass data so that shouldn't interfere if Uniden only looks at strings that begins with the characters that are used exclusively for GPS.

It is the RX data pin that should be used on the computer side and use a voltmeter on the GPS cable, if you peal off its isolation the red are +5v and the black are ground and the other two would be RX and TX but only TX should have some signalling. If it doesn't make sense when reading it on the PC it must still be sending it as a USB protocol and would need that cable that Phask suggests, if you have set a spanner mode.
