GPS Port on 996

[iamhere300]

Does anyone have a pinout, including voltages for the GPS port on the BC996T scanner?

I have a GPS that gets its DC power from a keyboard jack on a laptop, with the
data lines going to a serial connector. I want to try to get the 5VDC from the scanner
if possible.

My GPS gets 5v power on pin 1 but it does not take it from the scanner, it has a power converter that turns 12v in the car into 5v

Magellan 315 GPS - PC 9 pin serial cable pinout and signals @ pinouts.ru

don't know if this will give you any clues or not.

We found 5 VDC, but not at enough power to run the GPS. I am builiding a little box with a 5 volt regulator that will plug in to the same power as the scanner.

thanks though.

Maybe this is helpful , they use pin 9 to power the GPS:
( interesting is that pin 4 is marked V_GPS but is not connected ... )

Isn't the 12v there powering that little GPS module? The 5v is for the data?? Not enough to actually power a regular GPS?

That's not a GPS module, it is a voltage regulator that puts 5 volt at the 9 pin GPS connector so the external gps is powered by the scanner/

Thats real helpful. Thanks!

For those with a DELUO UNIVERSAL GPS receiver:
You will need:
Your 996T scanner
Multimeter (to check voltage and wires)
Philips screwdriver
Soldering Iron (no static one to void damaging other components)
Shrink tubes (to isolate the wires)
solder and solder flux
and no you dont need the hot sauce.


I did run into some road blocks trying to get power from the scanner into the GPS receiver and I wanted to share this with everyone. Could be of help to someone?!

After I solder the 7805A voltage regulator, I plugged in the GPS and ... no go. The scanner still said there was no GPS connected. I proceeded to check the PINs for voltage with the multimeter. There was power coming into PIN 9 (5v) and ground on PIN 5. So, as a test, plugged the extra wire PS2 plug stripped (red and black) wires directly into PIN 9 and 5 respectively. It worked. So of course my GPS receiver wasn't wired to receive power from PIN 9 in its factory serial. Being one of those sealed plastic serials I had to cut it off the wire and get a spare serial I had around which I could open and solder.
What I did was, using a multimeter, tested each of the 5 wires to see what PIN each one connected to.

So the DeLuo universal GPS receiver wiring goes as follows:

GREEN = PIN 2 (RX)
WHITE = PIN 3 (TX)
BLACK = PIN 5 (GND)
RED = PIN 9 (+5vdc)
SHIELD = Serial Ground

I then soldered all wires in the new serial appropriate PINs and BINGO! It started to scan for satellite signals.

Many thanks

Well Done! Nice to see some other folks adding features!

I forgot to add the picture showing the serials

Below you see on your left the original DeLuo serial.
Impossible to open the serial so as I mentioned above, I cut it and replaced it with the serial on the right. The kind you can open and solder the wires to each PIN. Doesn't look professional sorry.
Now all wires are connected in the serial. RX, TX, GROUNDs and the much needed 5 volts PIN9 feed coming from the 7805 voltage regulator.
