➀
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.
➁
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.
