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.
