GPS Receiver working with multiple scanners

[ofd8001]

I've got the Uniden GPS receiver installed in my vehicle for use with a 996XT.

Is there a way to make this receiver work on two scanners at the same time?

With a little tinkering and some equipment, one antenna can serve two scanners or one external speaker can server two scanners, so I was wondering if the same is true for a GPS receiver.

Generally no, because it's a serial data connection. It's a one-to-one connection.

One speaker connected to two radios is not a good idea.

There are devices like this (RS232 splitter | RTS as or ES-249 1 x 8 RS-232 Distribution Amplifier) that will take an RS-232 feed and send it out to multiple ports. Should allow a single GPS to handle multiple scanners. May be cheaper to get multiple GPS units though.

Yeah - that was my "generally"...

I'm running two 996XT's with a splitter and it works fine.

What type of splitter are you running the 2 996xts with

I ordered this off AMAZON. (DB9 1M / 2F RS232) for $5.99

Going back to the original Q/A, in a GPS system you can have as many "listeners" as you want, but you can only have one "talker." The GPS unit is considered a talker and all the scanners are considered listeners.

So will the cable listed above this post be OK to use to split a GPS between my 996xt and bcd536 without causing any damage

I'm hoping Upman was saying "Yep" because that's the exact set-up I'm hoping to accomplish.

That cable should not cause any damage.

I home-made mine but essentially it is what is pictured. GPS is shared between 996T, T15, output for mapping on laptop.
