cm300 Flash Upgrade

[epd1604]

Does anyone have any information about the procedure to upgrade these radios.
I have about 10 of them with firmware version 2 something and would like to upgrade them to r03.00.01.
I have the firmware but i am under the impression that a flash adapter is needed to perform this upgrade (fkn8096?????).

Does anyone have a pinout or schematic of one of these.

Also, i know that the gtf374 calbe will program these units but is it compatible with doing a firmware upgrade??

Any help will be greatly appreciated and thanks in advance.

I know the adapter I got that converts the standard radius/maxtrac cable to work with the cm300s has a switch on it for flash/program. I've never used it to flash a radio myself, but I would imagine that's what you're talking about.

As I recall, the adapter just jumpers a couple of the wires together, I'm not sure exactly what the flash switch does, but I wouldn't imagine it wouldn't be hard to modify a normal cable. I'll look into it more when I get a chance.

I knew somebody knew what it looked like in the inside.
Batlabs to the rescue again.

Thanks to all who gave input.

Is this for the ribless cable or for the standard maxtrac cable with rib.

Cause 2 and 5 are the maxtrac lines going to the radio.which per batlabs schematic is actually 4 and 7. but were is the jumper that jumps pin 6 and 8.

You can do the upgrade with a normal cable.
Start the upgradetool and run it to the point where you must set the flashadapter switch on.disconnet it and turn the radio off.make a bridge in the microphone jack (the both last springs in the upper right) and turn the radio on.Connect the programming cable and push "OK" in the upgradetool.

So i can take a rj-45 plug with last 2 pins jumpered and follow your procedure of "disconnet it and turn the radio off.make a bridge in the microphone jack (the both last springs in the upper right) and turn the radio on.Connect the programming cable and push "OK" in the upgradetool."

Ill have to try it tomorrow
