Route the speaker cable(s) through the rear panel cover and plug the two-
pin connector into the appropriate receptacle(s). You can use either of the
receptacles. It does not matter which way the connector is plugged in.
Route the data cable through the rear panel cover and plug the two-pin
connector into the two 1/4 inch phone jacks. Check your data cable wiring
and connectors using Fig. 31 or 32 on page 5-3.
Refer to “Optional Wall Box (WB-1)” diagrams included in this chapter.
Note: If you are operating a second scoreboard and are using one
console, scoreboards 1 and 2 are connected in series (or “daisy
chain”) via data cable. Plug the data cable used to connect score-
board 1 to scoreboard 2 into the remaining 1/4 inch phone jack
(the otherjack will have the data cable from the console plugged
into it). Plug the other end of this cable into one of the two 1/4 inch
phone jacks located in scoreboard 2.
If you are using a battery with your scoreboard, note the position of the
ON/OFF switch located on the right-side of the control board. Operation
of this switch is covered in chapter 6.
The switch must be placed in the correct position in order for
your scoreboard to operate correctly.
