[GreenKeys] ID Relay 35 ASR

[Ken Wiebe]

This relay (see pic) seems important. Line local relay?

I only have one of these and it's disconnected in a cardboard box. The only marking is CARD 334090 and it does in fact have card 334090 in it. I didn't find this part number in the parts list anywhere.

If this is the line local relay, I wonder why the thing works at all without it. Purely speculation, but maybe it has been bypassed?

My 35 has Offline/Line/Unattended modes. Offline is off. The motor runs and the printer prints when the mode switch is set to either Line or Unattended.

My current goal is to get a full duplex signal line hooked up and get the 35 talking on the line to an RS-232 device. So if anyone can give me like a checklist of what electrical components I need to confirm on the 35 that would be helpful and appreciated.

I have built the current loop/RS-232 circuit but I am also having trouble finding the full duplex pins 5-8 on the ASR so, there's that...the circuit isn't much good with no place to connect it. Arghhh.
