36 Sync Scorer Components
The function of the components and connectors on the table or single pedestal mounted Sync Interface
are:
(1) Speaker (J2) - Connection to the speaker. Connection that can be used as an alternative way
to connect the internal speakers. Currently this connection is not used. Refer to (4) Speaker /
Microphone (J9).
(2) Intercom Audio In (J5) - Input of the intercom audio(s) originating at the control desk Audio
Control box. If the board is located in the rst console, the cable comes from the control desk
Audio Control box. For the reset of the lanes, the cable comes from the Sync Interface PCB for
the previous lane. Refer to (3) Intercom Audio Out (J6).
(3) Intercom Audio Out (J6) - Output of the intercom audio for the next console. This connection
allows the continuation of the intercom audio(s) to the next lane. If the board is installed in the
last console and the signals do not continue, they are terminated using the termination jumper
JP4. Refer to (8) Audio Terminator (JP4).
(4) Speaker / Microphone (J9) - Connection for the microphone that is used for the intercom
system and the speakers used for the intercom, exciter audio, and keyboard beep.
(5) Comm/Power/Exciter Audio In (J3) - Connection for the power, communication and audio
exciter signals. When the board is located in left console (odd lane), signals for both the left
and right lane coming from the Primary Patch Panel of the Scorer Computer enter the board at
J3. If the board is located as the second keypad of the lane pair (even lane), the signals route
through the odd lane keypad then to this connector. Refer to (7) Comm/Power/Exciter Audio
Out (J4).
(6) Comm/Power/Exciter Audio Out (J4) - Connection for the communication, power and audio
exciter going to the second keypad for the lane pair. This connection is only used on the left
(odd) lane keypad.
(7) To Sync Interface (J8) - Connection used only in dual pedestal installations that connects
the intercom, exciter audio, and communication signals to the Touchpad Interface PCB. This
connection is not used in table mounted or single pedestal touchpad installations.
(8) Audio Terminator (JP4) - Jumper used to terminate the intercom audio signal. If the intercom
audio cable does not continue to another console from J6, terminate the signal by placing a
jumper between pins 2 and 3 (T). Otherwise place a jumper between pins 1 and 2 (U).
(9) Microphone (J7) - Connection that can be used as an alternative way to connect the
microphone used for the intercom system. Currently this connection is not used. Refer to (4)
Speaker / Microphone (J9).
(10) Diagnostic LED (D3) - This light ashes to indicate that the PCB is functioning properly.
(11) To Touchpad (J1) - Connection to the keyboard in the console.
(12) Speaker/Microphone Assembly - The microphone that is used for the intercom system and the
speakers used for the intercom, exciter audio, and keyboard beep.
