3-2 CI-PM-3 Paging Modulator Instruction Manual
3.4 Installation
1. Install the Daniels EC-96 Extender Card in either the far left-hand or the far right-hand slot of
the subrack (as viewed from the front). Remove the side covers of the CI-PM-3 Paging
Modulator and attach the 96-Pin Extender Cable between it and the Extender Card.
2. Apply +13.8 VDC power to the Subrack. Allow approximately 15 minutes for warm-up.
3.5 Alignment
Refer to Figure 5-1 for the location of the CI-PM-3 module front panel controls.
1. Ensure the CI-PM-3 circuit board jumpers are initialized to their default settings (refer to
Table 4-4). Note any differences so that the jumpers can be returned to their former positions.
2. For alignment procedures in this section, set the front panel switches to the following settings,
unless otherwise noted:
a) SW1 (FREQ REF) set to INT
b) SW2 (MODE) set to SETUP
c) SW3 (SET MOD) set to 2 LEVEL
d) SW4 (SET DEV) set to Data “1” (Top Position)
3. Ensure the Transmitter Audio Processor circuit board jumpers are initialized to their default
settings (refer to Tables 4-7 or 4-8).
4. Connect the CI-PM-3 REF OUT connector to the transmitter REFERENCE INPUT connector
via a SMA to SMA RF cable.
5. Remove external connections to the DB-15 connector on the CI-PM-3 or the Alarm lines on the
back of the subrack.
Do not connect any other input signal/control lines to the CI-PM-3 at this time.
3.6 Frequency (Digital Paging) Adjustment
CI-PM-3 frequency adjustments are factory set. It is strongly recommended that they not be
altered. The following procedure applies only if field adjustment is required:
1. Set front panel SW1 (FREQ REF) INT and remove shunt jumper JU6-A.
2. Set shunt jumpers JU23-A and JU41-B.
3. Set the transmitter front panel NORM/KEY TX switch to KEY TX.
