Board Setting
Before installing this board, the following settings should be made by qualified service per-
sonnel or system installers.
1. Set switches (SW1) on the board to designate the monitor output board number as
shown in the following table.
The factory default setting is Board Number 1.
Cautions
• Board Numbers 5 to 8 are only used when the WJ-
AD550 Extension Unit is used.
• Board Numbers 1 to 4 should be installed in the WJ-
SX550A Matrix Switcher and Board Number 5 to 8 in
the WJ-AD550 Extension Unit.
Do not install more than 5 boards in the WJ-SX550B
Matrix Switcher.
2. Set switches (SW2/SW3/SW4/SW5) on the board to
meet the alarm reset output requirement as either Open
Collector (OPEN C.) or Pulse (VTR).
The factory default setting is Pulse (VTR).
Open Collector (OPEN C.): 16 V DC 100 mA max.
Pulse (VTR): +5 V DC approx. 500 ms
Note: Be careful when setting these switches as the
switches are not physically located on the board in
numerical order.
Switch location from the top of the board, going
downward, is: SW4 (reset out 3), SW5 (reset out 4),
SW3 (reset out 2) and SW2 (reset out 1).
