4.3.3 Plug-In Modem Card (P/N
537-4870) with mounting screws
(P/N 101-4038) and standoffs (P/N
107-9440) (Previous Generation Processor
Board)
The E2’s internal modem mounts in the PC-104 slot
located at the top left edge of the E2 main processor board
(See Figure 3-18 on page 3-6). Disconnect power to the
unit, and carefully plug the male pins on the back of the
modem card into the E2’s PC-104 slot. Use the standoffs
and screws supplied with the modem card to secure the
card to the main processor board, as shown in Figure 3-18
on page 3-6). When finished, restore power to the E2.
4.3.4 Plug-In Digital I/O Network
Card (P/N 537-4880)
This card adds two user-programmable digital outputs
and two digital inputs to enable connection of switches
and relays (relay contacts are rated at 3A up to 24 VAC).
The plug-in Digital I/O Network card connects to the
power interface board to the right of the two fixed RS485
I/O Network connectors.

4.3.5 E2 RS485 Port Card (P/N
537-4890)
The E2 main board has two RS485 Network channels,
allowing you to connect input and/or output boards via the
RS485 Network. This optional card adds a second RS485
port (COM4) to the E2, allowing a connection to the ISD
compressors, Control Link devices, and other supported
MODBUS devices.
The plug-in RS485 Network card connects to the
power interface board between the two fixed RS485 I/O
Network connectors and the battery.
