RS485 HD Termination Resistance Switch
In Multiplexer applications, enable the termination resistor (ON) ONLY
on the last device of the chain, the farthest away from the Multiplexer
(assuming the Multiplexer is the first device of the chain). On all the
other devices, disable this resistor (OFF).
TCNM-ACBB1 Backup and Restore Module (Accessory)
The TCNM-ACBB1 Backup and Restore Module (separate accessory) provides configuration parameter
backup. It can easily be installed by aligning it over its corresponding connector in the TCNM-ACBB1 and
pushing down until correctly seated. When closed, the plastic support inside the TCNM-ACBB1 cover
holds the module in place. For further details see the TCNM-ACBB1 manual.
