Connecting readers
OSDP (RS-485) signaling requires two 2-conductor
cables. One cable for power (18 AWG) and one
cable for communication (24 AWG, shielded,
twisted pair).
Wiegand or Clock/Data (TTL) signaling requires a
4-conductor cable (18 AWG, shielded) with additional
optional conductors for LED and beeper control.
CAUTION
Readers that require different voltage or have high
current requirements should be powered separately.
Refer to the reader manufacture specifications for
cabling requirements.

Note: For OSDP cable lengths greater than 200 ft
(61 m) or EMF interference, install 120Ω +/- 2Ω resistor
across RS-485 termination ends.
Note: Data 0 and Data 1 wires for Wiegand may be
reused for OSDP. However, standard Wiegand cable
may not meet RS-485 twisted pair recommendations.
The reuse of cable works best on shorter cable lengths
at lower data rates.
