To use a channel in TTL, jumper the appropriate

TTL pin to the appropriate RET.

To use Channel 1 in TTL, jumper pin 9 to pin 11.

Signal types can be mixed in any combination on

the CFM module.

For new installations, terminate the shields at the

chassis. While not recommended, existing

installations can continue to terminate the shields

at the return (RET) terminal.
