XPR 5550 Remote Adapter?

[TX_Shooter]

The Air National Guard base where I'm installing a telephone system is acquiring 3x Motorola XPR 5550 radios for their civilian equivalent emergency services (state police, county sheriff, local police departments, ambulatory services, etc., etc.,).

I've opened other topics within this forum about how to possibly integrate these and other radios into our telephone system as a means to diversify their usage across several buildings from one location, and have met with some success, but have hit a roadblock on how to channel the XPR 5550 remotely.

The local dealer gave us the pins to use on the rear accessory connector for the remoting of the the transmit, receive, and PTT, but so far we can't figure out how to channel this radio remotely, a function that is necessary in the event of a major emergency (plane crash, hurricanes, etc.). The local dealer selling these radios wanted to additionally sell the L3276 Tone Remote adapters, but in reading about that, and not having found any technical information on the radio itself via the internet, I'm not so sure that L3276 is right for the job. According to Jim on this forum, and a few others pitching in their comments, this adapter is designed a type of DC binary channeling, putting grounds on specific pins of the accessory connector in order to tell it which channel to select. For the life of me, I can't figure out how to wire the L3276 to the XPR 5550.

We won't get these radios until late this week, along with the CPS, and that will only give us about 1/2 day to figure things out... this job ends this Friday, and then we pack up and go on to the next one over the weekend.

Anyone have any experience remote channeling the XPR 5550? Is the L3276 the correct adapter to do this?

Many thanks to those that can help us.

What is going to be sending function tones to your adapter? There's no reason the L3276 wouldn't work as long as it's receiving the proper functions from the console...or in this case the PBX??

Well, we've got a few options on that. Our PBX can send the standard Motorola EIA Tones (TRC) to it via the CSI Flex II on balanced 4-wire TX+RX, or if it calls for it we can use the DC binary setup (which we've not really done before, but isn't a problem to do with our equipment unless latency is a concern). I don't know what the L3276 needs to make it work. As it is now, I'm unable to figure out how to wire the L3276 to the XPR 5550 radio, let alone how to set up the XPR 5550 in order to be ready for the L3276. The L3276's radio interface tables don't appear to match up with the accessory connector on the back of the XPR 5550.

I'm guessing we'll need the DDN6340 cable, but how do you pin it to this radio's accessory connector?


Basically, tell me what the L3276 needs and how to wire it to the radio, and I can probably make it happy.

Have the radio supplier provide you a programmed and assembled (including alignment) package.

An alignment package?? Could you describe what that entails?

Disregard... the coffee hadn't kicked in when I read this early this morning. (Alignment package... sheesh!)

He's saying have the dealer sell you a complete package with all the work done including setting levels (alignment). I'm inclined to agree. With no time left, I'd put in the CSI panel, demonstrate how it works, and let the dealer connect their radio to it.
