Guide (49289).

1.0 The ISC Board

The ISC board contains the following

components (Refer to Figure 1):

A. two (2) unsupervised alarm inputs

B. one (1) RS-232 or RS-485 interface

C. two (2) downstream RS-485 interfaces

(which can consist of one 4-wire and

two 2-wire interfaces)

D. a set of three (3) status LEDs

E. one (1) bank of eight (8) dip switches

F. eleven (11) jumpers

G. one (1) power-in input

H. and one (1) memory backup

(3 volt lithium) battery

I. one (1) TCP/IP Connector

If either of these inputs is not used, a jumper

wire should be installed.

If RS-485 communication is used, an RS-232

to RS-485 converter is required at the host

workstation.

This configuration will work for Direct Connect

(RS-232) and Lantronix Ethernet network

communications. With direct connect, or Dial-up

DIP switch 5 needs to be OFF, and with Lantronix,

DIP switch 5 needs to be ON.
