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.
Caution: Observe POLARITY on 12 VDC.
Caution: ATTENTION: Observez la polarité du 12 VCC

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.
