mitsubishi electric outputs and alarm

[al]

My peoples

What do i need to do to get an alarm output and remote on/off for a mitsubishi electric: pca-m140ka, i presume i need an interface?

You will probably need the PAC-SA88HA 5 wire adapter. Best check with Mitsubishi in case the part number has changed.

Thank you Hyper!

For the remote on/off, is it a pulsed signal ie one pulse on, further pulse off?

No, it is not a pulse signal. SW1 is for remote control block and SW2 is for ON/OFF

Thanks Narkom, the 5 wire has a different set up though:

Orange and green for fault and red and brown for on off?

CN51 connector is for Fault status (3-4 contacts) and Operation status (3-5 contacts).The output voltage is 12VDC.
The red and brown wires are not in use.
For On/off control you should use CN32 connector as I described above. It is potential free connector.
