Supplying Power to the PW-7000 Interface
The processor accepts 12 VDC for power. Locate power source as close to the unit
as possible and connect it with minimum of 18AWG wires.

Communications Wiring
The PW-7000 processor communicates to the host via on-board Ethernet 10Base-
T/100Base-TX port.
The serial I/O device communication port (TB1) is a 2-wire RS-485 interface which
can be used to connect additional I/O panels. The interface allows multi-drop
communication on a single bus of up to 4,000 feet (1,219 m). Use 1-twisted pair
with drain wire and shield, 120-ohm impedance, 24 AWG, 4,000 ft. (1,219 m) maxi-
mum for communication.
Caution: Observe POLARITY on 12 VDC.
Caution: ATTENTION: Observez la polarité du 12 VCC
