CM200 Programming Issue

[DisasterGuy]

All- I am running into an issue with a batch of CM200's. It is pretty rare I deal with the Commercial Series but just inherited a system employing these for FXO use. I typically program these with a standard RLN4008 RIB and AARKN4083 Program/Test Cable using the FKN8113 adapter. These radios however are set for ignition sense for some reason of the accessory connector so I can't program them since they power down when the accessory connector is removed and the AARKN4083 does't provide ignition power.

I broke out my hand-dandy maxtrac cable that I made 15 years ago, shorted pins 6 & 8 of the RJ45 (MOT would call these pins 1 & 3) however no luck getting CPS to communicate with the radio at all. I am using Commercial CPS R05.18 that is the most recent available (double checked MOL Resource Center).

Any ideas? I hate to drop the coin on the "new" RIBless CDM cable and adapter since that would come to over $300 just to update 15 radios.

Shorting 6 & 8 won't work. All you have to do is apply +12vdc to pin 10 of the accessory connector and you've got ignition sense.

Good point, I will have to take a look at the FKN8113 to see if I can add a pigtail to pin 10.

If you're doing it on the bench, why not just run a jumper off the power supply? My Motorola power supplies actually have a small red +12vdc wire coming off the radio end connector for exactly that purpose.

When I set up a mobile for use as a base station, I program it for both Ignition Sense and On/Off and then run +12vdc to Pin 10. That way, if there is a power failure, the radio will power back up on its own when the power comes on.

I.wish this was a bench job. These are in a SCADA like service (outdoor siren system) working in NEMA 4 boxes 10' up on poles.

And how do you figure $300? Go to ebay and get this cable and you do the programing thru the mic connector and not the accy jack. Just make sure you use the correct com port.

i was thinking these are the same as the PM300's? have a on\off vol control? we have a few PM-300's and don't use the IGN on them just the main power is IGN on\off the radio does turn on and off with IGN?

I don't use eBay cables nor do I have the ability to do procurement through eBay. If I was going to buy a cable from eBay I would just build it myself. I do stand corrected that the cost would be $200 for the cost of the RKN4081 ($161.70) and FKN8096 ($50.05) using my current MOT pricing. I have no problem buying a new cable and adapter if needed, I'm just curious why my old (personal) working Maxtrac cable wouldn't program after jumping the two pins that appear to be the only thing different in the CM cable. The only other variable would be my RIB. While I don't use it all that much these days I did test it with reading a PM400 using the AARKN4083 and FKN8113 adapter.

I think that Steve hit the nail on the head though regarding just adding a pigtail onto pin 10 of the FKN8113 to allow me to deliver ignition sense while using the AARKN4083 through the accessory connector. The more I think about it, it baffles me that the AARKN4083 and FKN8113 don't have such a pigtail.

In general, the CM200, CM300 and PM400 are very similar (they share CPS and service manuals). They do all have power as part of the volume pot so in this installation there really is no need for IGN as they will come right back on after a power failure (although they each have backup batteries anyway).

i always had to use the old Maxtrac Programing cable and rib box with the FKN8096A to program the PM300 Radios

Simple cable:

DB25----------------RJ45(10 position) tab down, left to right: 10-1-2-3-4-5-6-7-8-9
1-------gnd-------------4
12-----sw A+---------1
15-----bus +----------7
25-----boot ctrl-------6
16-----tie point-------3

Jumper pins 4&13, and add 1Kohm resistor between pins 12&16, on DB25 connector.
