Looking for the pinout for the GPS interface on the SDS100

[W2GLD]

Does anyone have or have come across the pinout for the two accessory connectors on the Uniden SDS100? UPMAN, can you help us out as these are absent from the manuals I've come across so far.

They are USB.

 

[jonwienke]

The jacks are standard USB mini and micro and the pinouts are widely available online.

The only quirk is that the GPS input goes to the ID pin (next to ground) of the USB mini jack.

 

[W2GLD]

Awesome, thank you both. Yeah, I knew the pinouts on the USB side; just wasn't clear where the GPS input was; I never would have guessed that pin. Thank you...

 

[UPMan]

Jon: Check your PM.

 

[W2GLD]

I just realized that you were talking about the USB-mini connector where power and programming are also performed; what I was actually hoping/looking for was for the secondary USB-micro connector to see about putting GPS there. I had assumed that this connector is what replaced the older style one Uniden was using on the BCDx series scanners. Is this not the case?

 

[UPMan]

I don't believe the micro can be used for GPS.

Could you clarify that using the pin numbers from the picture? My GPS only has 4 wires.

 

[blantonl]

The vast majority of USB Mini-B cables never connect the ID pin to a wire.

Do you know which wire goes to the ID pin? My GPS has red, black, white , green, bare w/ shield.

I order some of the connectors Jon listed along with some USB A male. My plan is wiring the male A for 5vdc on a separate leg. In other words, The gps wires to the micro usb and 5vdc coming in from the male A. Of course I still need to figure out the wiring.

It seems that red/black are the 5vdc. But what are the white/green/bare?

 

[jonwienke]

Green and white are USB Data+ and Data-. Shield is the RF shield--grounded to black at the A end of the cable.

Thanks Jon,

I'm still trying to figure out your comment on post #3 "The only quirk is that the GPS input goes to the ID pin (next to ground) of the USB mini jack"

ID is pin 4, which wire is this?

Connect the data coming from the GPS to that ID pin.

 

[jonwienke]

The GPS wires are not the same as USB, it uses RS232 signalling. Which puck do you have?

GlobalSat BU-353S4, I cut of the serial to USB end (uses the prolific driver)

So instead of instead of going to D+, solder tx to ID?

 

[mancow]

Is 5v available out on any of those ports? I assume not.

You need the straight serial version..

When I plugged the GPS into the scanner with a conversion cable the GPS was not powered. When I plug the GPS into a USB power source it powered up.

I'm planning on no power at the port, and charging the scanner when I have the GPS plugged in.

Do i have the equivalent now that I cut off the prolific chipset/USB plug?

 

[bmdoss]

I am not sure about that..
