11.5.5 Accessory Boards

The Accessory Boards are the LIL Network board, Ethernet board, LonWorks board, RCB board, and RTC/CB
board. Each of these boards mechanically fastens to and electrically connects to the MPU Controller board as shown
in Figures 11-1 and 11-5.
The following steps outline the board replacement procedure.
1. Remove the MPU Controller board from the case as described above.
2. Remove the hardware fastening the selected Accessory Board(s) to the MPU Controller board. Save the
hardware.
3. Carefully unplug the Accessory Board(s) from the MPU Controller board.
4. Before installing the replacement board, read the installation statements below for the particular board type.
Then, plug a new or replacement Accessory Board into the mating board and refasten the board(s) with the
hardware saved in step 2.

Ethernet Network board (Figure 11-7) - This board must be installed on a compatible MPU Controller
board. This Controller board has the lithium battery that lies flat on the board and W8 is the Real Time
Clock jumper; see Figure 11-2. The Ethernet board plugs into connector J3 and jumper W2 on the MPU
Controller board. Jumper W2 may need to be set, as described below.
Removal and installation of the Ethernet Cable is discussed and illustrated in Section 11.5.6.
•
LonWorks board (Figure 11-8) - This board plugs into connector J6 and jumper W4 on the MPU
Controller board. Jumper W4 may need to be set, as described below.
•
