• Provides a 2400-baud FSK modem that operates over the 33-ohm page line
• Detects both Page line and Party line ground fault detection (less than 5000 ohms)
• Detects off hook conditions on both party lines (less than 120-ohms across L1 and L2)
• Allows party line switching from the 33-ohm party lines to the 33-ohm backplane
• Receives one external dry contact closure input
• Provides one output to drive an external relay for special applications
Functions of Mode Tw o - Control Area
Mode Two includes all of the functions of Mode One excluding FSK communication plus the following:

• Hex switch (S2) sets the PCBA ID number
• For PPIs 1-14, short pins 2 and 3 of jumper J7.
• For PPIs 15 and 16, short pins 1 and 2 of jumper J7.
• Valid PCBA ID’s are: 01-0E, and 11-12[hex]
PCBA ID Example:
PCBA ID 0 A (hex)
/ /
Equals 0 when J7 pins 2 and 3 are shorted ----/ / Set by switch S2
Equals 1 when J7 pins 1 and 2 are shorted ----/
• Valid PCBA addresses are: 0x0200-0x03F0 [hex]
Address Example:
Address 2 E 0 (hex)
/ / Fixed
/ / Set by switch S1
Equals 2 when W1 is installed ------/

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.

10. Set the page line balance adjustment as described below:
Page Balance
The Page Balance is used to set the line loading of the page zones page line. After all stations are
connected to the card, the Page Balance is set. Use a station connected directly to the PPI. Squeeze
the pressbar on the handset and blow steadily into the mouth piece. Listen to the sidetone in the
receiver. Adjust the Page Balance until a minimal side tone is obtained in the receiver. The Page
Balance does not require readjustment unless 10 or more stations are added to the zone.
OTE: If a handset station is not available for use as indicated above, perform the following steps:
N
• Connect a true impedance meter to the page line of the appropriate PPI.
• Adjust the line balance potentiometer to a reading as close to 33 ohms as possible
11. Set the monitor level adjustment, if used:
Monitor Level
The Monitor Level can be adjusted during system start-up. This is required only
Receive has been selected during the jumper configuration. Have an individual go to the nearest
Page/Party
®
Station and talk on the Page Line. Adjust the Page Monitor until the desired level is
if the Monitor
achieved.
12. Verify that the PPI properly routes audio and communicates with the external devices as indicated in
the system manual
Operation
The operation of the PPI is controlled by the MCU. See the MCU configuration details in the system
manual for all PPI operational information.
