3.4.1 Mounting PC-104 Cards in
E2 (Previous Generation Processor
Board)
3.4.1.1 The Internal Modem
The E2’s internal modem mounts in the PC-104 slot
located at the top left of the E2 main board (See Figure 3-
18). 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 board, as
shown in Figure 3-18. When finished, restore power to the
E2.
3.4.2 Two-Channel and Four-
Channel Repeaters
3.4.2.1 Mounting Repeaters Overview
Repeaters are used to extend the maximum length of a
segment of Echelon cable, or to act as a bridge between
two devices that are farther apart than the cable’s maxi-
mum node-to-node distance. Retail Solutions offers two
versions of repeaters for the E2 controller: an external
two-way repeater that comes in an enclosure (P/N 832-
1010), and a four-channel repeater mounted in the E2 (P/N
832-4830).
For more information about installing repeaters and
routers, please refer to the Repeater and Router Installa-
tion and Networking Guide (P/N 026-1605).
3.4.2.2 Mounting the Two-Channel
Repeater
The external repeater (P/N 832-1010) is externally
mounted within its own enclosure.

NOTE: Because the modem/communication
expansion card and four-channel repeater card
share the same mounting platform, they must
be used separately.
CAUTION: Power down the E2 before plug-
ging the modem into the PC-104 slot. Failure
to do so can damage the modem and void the
warranty.
