1. Mounting the X100
2. Communication wiring
Connect the X100 to the Aero X1100 intelligent
controller using IO Module ports (2-wire RS-485).
Use 1-twisted pair, shielded cable, 120Ω impedance,
24 AWG, 4,000 ft. (1,219 m) maximum.
Note: Both IN and OUT terminals on the IO MODULE
are the same port and are internally connected.
Setting the termination jumpers
Install RS-485 termination jumpers on the interface
boards at each end of the communication bus only.
Failure to do so will compromise the proper operation
of the communication channel.
