Wiring
INPUT WIRING: maximum distance of 300m (1000ft)
from the Reader Expander when using 22 AWG.
AUX WIRING: Min 22AWG Max 16AWG.
(Depends on length and current consumption).
For wire/cable size, a maximum of 5% voltage drop at
the terminals of the powered device has to be observed.
MODULE NETWORK WIRING: Recommended
Belden 9842 or equivalent. 24AWG twisted pair with
characteristic impedance of 120ohm or CAT5e / CAT6
are also supported for data transmission when using
ground in the same cable. Max 900m (3000ft).
Do not use extra wires to power devices.
CAUTION: INCORRECT
WIRING MAY RESULT IN
