Motorola RICK cable

[K2NEC]

I have a an HLN3333 RICK that I don't have the cables for. I found the pinout for it in a manual but I'm wondering if I really need to use all 16 pins or if I can get away with only using the necessary pins between the RICK and CDM? If that's the case, which ones are really necessary?

I'm trying to cut a corner but maybe just doing all 16 pins is the best thing to do, I'm gonna be using the connector anyway, might as well make the most of it

Just use the pins you need. Only a few applications need all stuff. It was easier to ship the RICK with 2 cables with all wires than multiple cables.

Ok so things like speaker out and the pins that are selected in CPS?

Yes.

The accessory plug connections can be reasonably modified within CPS. IIRC, pins 3-6, 8,9,11,12 and 14 are either fully or partially programmable, or are limited to either in or out only. A few of them (pin 3?) can only be active low, and some of them are analog only (9 if my failing memory is correct). You can poke around in the CPS and see which are which.

[edit] fixing the most egregious grammatical atrocities.

Ok perfect, sounds like I can make do with a Cat5 cable instead of having to get a 16 wire cable

Worst case if you wanted to cover all your bases would be to use 2 Cat5 lengths and heat shrink or zip tie them together. Wouldn't be the first time I saw a multipin cable made in that or a similar way.

You just need the 4 basic connections to the radios, Tx audio, Rx audio, COR, and PTT. Very easily build if you have two of those 20-pin rear accessory plugs that came with the GM300 or M120 radios. Those plugs can easily be found on ebay as a kit with virgin pins included.

Perfect...time to go shopping

I forgot to mention one +12V to power the RICK, and the respective grounds to each radio, but guess you already knew that.

Yea I figured as much since the RICK needs power, nevertheless 6 wires is better than 16

More like 32 wires, 16/radio.
I am guessing those original connecting wires must have been easier/cheaper to manufacture that way because there is simply no way to justify all of them.
