Model PDP Series 200 maxDPU4E Hardware Guide

Serial port 1 is a nine pin RS-232C port that is used to update the DPU BIOS

and firmware, if necessary.

Serial port 2 is a twenty-five-pin serial port that supports multiple interface

standards. This port will be used by the DPU to interface with external PLC

type equipment.

maxNET Interface Ports

Dual Ethernet 10Base-T ports are provided to interface with the maxNET

communication network. These ports run at 10Mbps, full-duplex.

Backup Port

A 100Mbps Ethernet interface is provided to pass database information to a

hot standby DPU. A custom Category 5 Ethernet cable (Part 089424) is used

to connect both DPUs via this port. A status signal is also passed between

DPUs through this port to indicate which DPU is in control.

Three Rotary Address Switches

Three rotary switches set a unique IP address extension for the DPU. The

DPU network A IP address is 172.16.x.y where x is read from the high

network switch while y is the combination of the middle and low network

switches. The network B IP address is 172.17.x.y. See Chapter 3, "DPU

Switch Settings and Button Controls," for a discussion of these switches.

Mode Switch

The Mode Switch is a 16 position rotary switch. The DPU reads the switch

during a reset or power up cycle in order to determine the desired operational

mode.

Key Switch

The Key Switch requires a key to change the operating mode of the DPU

from Off-line (monitor inputs but do not change any outputs) to Run (normal

operation) to Locked (normal operation but the DPU will not accept a full

database download).
