Address Setup And Termination Resistor - Daikin iTM plus Installation Manual

2.1.3

Address setup and termination resistor

For each iTM plus adaptor, a unique address needs to be set. The number for the intelli-
gent Touch Manager is always set to "1". Therefore, the setting range for the iTM plus
adaptor is from "2" to "8".
Use the plus ADP ADDRESS switch on the front face of the iTM plus adaptor to set the
address.
Moreover, the termination resistor needs to be set for the iTM plus adaptor which is the
farthest from the intelligent Touch Manager.
To set the termination resistor, change the position of the TERM switch on the front face
of the iTM plus adaptor to ON position.

NOTE
If the two LEDs, CPU ALIVE and ALARM, both light up during power-on after installa-
tion, there is a possibility of a problem with the address assignment:
• An invalid address is set. ("0", "1", and "9" are not allowed.)
• A duplicate address is used.
You must assign a unique address between 2 and 8 for each iTM plus adaptor. Power
off the unit once, check and correct the address, and then turn it on again.
Check the status of the two LEDs, CPU ALIVE and ALARM.
