3.6 Communications Wiring
The PW-6000 processor communicates to the host via on-board Ethernet
10Base-T/100Base-TX port or on port 1. Port 1 may be configured as RS-232,
two-wire RS-485 or optional Lantronix Ethernet 10Base-T/ 100Base-TX
CoBox-Micro interface. The RS-232 interface is for direct one to one connection to a
host computer, or a modem.
Ports 2 and 3 use the two-wire RS-485 interface only. The interface allows multi-drop
communication on a single bus of up to 4,000 feet (1,200 meters). Use shielded
twisted pair (minimum 24 AWG) with 120-ohm impedance. Install termination
jumpers only at the end-of-line unit.

3.7 Cabinet Tamper and Power Failure Input Wiring
Figure 4: PW-6000 TMP and FLT Terminals
Inputs TMP and FLT are used for monitoring cabinet tamper and power failure with
normally closed contacts. These two inputs are for contact closure monitoring only; do
not use end-of-line (EOL) resistor(s). If these inputs are not used, install a short piece
of wire at the input to indicate a safe condition.
