Can't Communicvate with RC-80B

[jpape]

I have installed an RC-80 in my basement for control of the heating automation. The stat works fine as a standalone unit, but I can't seem to get Homeseer to talk to it. I have downloaded the plugin and connected the RC-80 via the correct serial pinout and all I get are timeout trying to write to the unit. I'm going to recheck my wiring, can someone give me what their working serial pinouts are?

Thanks, Judd

1. On the DB-9F connector: Connect pins 7 and 8 together. (RTS and CTS)

2. On the DB-9F connector: Connect pins 1, 6 and 4 together. (DCD, DTR
and DSR)

3. Connect pin 4 of the DB-9F to the YELLOW wire on the thermostat plug
(DTR)

4. Connect pin 3 of the DB-9F to the GREEN wire on the thermostat plug
(TXD)

5. Connect pin 2 of the DB-9F to the RED wire on the thermostat plug
(RXD)

6. Connect pin 5 of the DB-9F to the BLACK wire on the thermostat plug.

Also make sure you have the stat set to serial communications mode. The default is HAI panel communications mode from the factory.

I agree with jpape. I don't think your problem is with the wiring. You need to make sure that you change the communications mode on your thermostat to rs-232 mode. If you need directions on how to do that I can get them for you tonight.

Well it turned out to be my adapter I used to go from DB9 to RJ45. I rewired it last night and I'm now able to talk to the RC-80. Time to play!!!!
