Batboard

Ok... I have the audio connections for both TX and RX. I DO NOT want to have to spend lots of money for tone remotes. Does anyone know where I could pull PTT from?

its all fed on data busses.
you can do with an auxio board II
bln6664 is im not wrong

What he wants is called "relay keying".

It is set up in The CCII RSS BIM programming.

The I/O card need to be configured for output 5 which then provides the PTT.

Question 1: Does the BIM card have a jumper or dip switch to configure PTT?
Question 2: Is PTT normally on as a default?

Thanks,

Answer 1: No. The BIM only has DIP switch settings to indicate the TDM address (DIP 1-7) and whether it is a BIM or TBIM (DIP . The jumper settings control things such as MUXbus/BUSYbus settings, 2/4 Wire domestic or international, guard tone frequencies, ambassador/local, etc. but have nothing to do with PTT. In fact, the BIM is strictly an audio device, hence the reason an AUX module above the BIM is required for PTT/COR. The COIM actually instructs the AUX module to close it's relay for PTT, and detects the COR on receive (should you choose to interface RX that way instead of VOX activity detection).

Answer 2: Maybe. I seem to recall that Relay Keying gets enabled by default on CCGE CEB's, but I could be wrong. It's been so long since I worked on Series II Plus that I don't remember if it is or not. A little experimentation will answer your question for you - install a properly configured AUX module and see what you get.

The issue is, if you have tone keying enabled as well, you're going to need to shut it off as your transmitter will give you HLGT + Function tone + LLGT (BIM mode) or HLGT + LLGT (TBIM mode) during the transmission.

Anyone still using DC keying should be dragged out and electrocuted.
