Monitor Transmit: To transmit audio to the monitor bus
Relocate jumpers J6 and J8 to the Monitor Transmit Enable “EN” position (short pins 1 and 2) and
jumpers J11 and J12 to the Monitor Transmit “FA” position (short pins 1 and 2). Also, relocate
jumpers J9 and J10 to Monitor Receive Disable “DIS” position (short pins 1 and 2).
Monitor Receive: To monitor audio from the monitor bus
Relocate jumpers J6 and J8 to the Monitor Transmit Disable “DIS” position (short pins 2 and 3) and
jumpers J11 and J12 to the Monitor Transmit “CA” position (short pins 2 and 3).
Also, relocate jumpers J9 and J10 to the Monitor RCV Enable “EN” position (short pins 2 and 3).
3. Remove existing PPI from card rack assembly.
4. Install the replacement PPI as described below.
Align the PCBA into the upper and lower tracks of the assigned slot. Slide the PCBA towards the
rear of the card rack until it comes in contact with the backplane connector. Firmly press on the front
bezel until the PCBA is seated. Secure to the card rack by tightening the two screws located on the
front bezel (See Figure 1).
5. Apply power to card rack assembly.
6. After a brief delay, the On Line LED on the PPI will illuminate.
7. The RTS LED flashes continuously if SmartSeries stations are configured to communicate with the
PPI.
8. The EOL FAULT LED will NOT illuminate. This LED only illuminates when an End-of-Line
(EOL) device is not responding to the PPI.
9. The GND FAULT LED will NOT illuminate. The LED only illuminates when a GND fault is
present on the page line or Party Line 1.
