1. GENERAL 1.1 Introduction The CI-PM-3 Paging Modulator module is an optional plug-in component of the MT-3 Radio Repeater System. This module provides digital and/or analog paging capability for Daniels MT-3 transmitters in all supported frequency bands. The CI-PM-3 is designed for low power consumption. typically drawing less than 250 mA in steady state. In its standard configuration, the CI-PM-3 uses an on-board frequency reference source consisting of a 10 MHz COCCYX with a standard stability of 0.
1.2 Construction The CI-PM-3 Paging Modulator is packaged in 2 compact Euro standard shell module housing of nickels tee! with an anodized aluminum front panel. Corrosion resistant fasteners are used throughout the assembly. 1.3 Printed Circuit Board Numbering Convention To ease troubleshooting and maintenance procedures, Daniels Electronics Limited has adopted a printed circuit board (PCB) numbering convention in which the last two digits of the Circuit Board number represent the Circuit Board version.

2. THEORY OF OPERATION The CI-PM-3 Paging Module circuitry can be divided into three main functional blocks: Paging Signal Path, OCXO/PLL. and Configuration Options. The Paging Signal Path includes signal conditioning circuitry which is used to level and edge-condition the incoming data signal, then band Limit it for transmission. The OCXO/PLL circuitry develops a high stability 10 MHz reference signal for the transmitter.
positive and negative deviation limits of the modulated signal as set by R5/Ul3c and R6/U13d, respectively. The output of U9c passes through Sulfa which is normally closed for 2-level signals. and through U7b which is normally closed for digital signals. to input buffer Udall of the 6-pole Butter worth Filter comprised of U14b, Could and Dull. The output of the Butter worth Filter is low-pass limited to 3400 Hz. and is sent to TX A and/or TX B DIR MOD (band pass) inputs via Tulsa and Bulb.
to the square wave generator UL and the square wave frequency selector U7c. Switch UTe places R72 in parallel with R41 in the feedback circuit of U 17¢ through Dull, causing UL to oscillate at approximately 10 Hz. This signal causes the front panel DATA indicator. LED. to flash at a rate discernible to the naked eye. 2.1.2 4-Level Digital Paging For 4-level data operation, front panel SW2 must be in the NORM position, Mode Override jumper JUT must be in the A position.
2.2 OCXO/PLL The main component of the OCXO/PLL circuitry is the 10 MHz Novelized Crystal Oscillator (OCXO). which provides the (standard) PPM stability reference signal to the front panel REFERENCE INPUT of the MT-3 Transmitter. This circuit may also be configured to phase-lock to a GPS or WWV referenced high stability 10 MHz signal via the front panel REF IN SMA connector to generate a higher stability reference signal of PPM. 2.2.
The CI-PM-3 has been designed for use in stand-alone base paging transmitter applications as well as multiple-transmitter systems. A multiple-transmitter system normally consists of a local base station paging transmitter and one or more remote paging transmitters which regenerate the paging signal and extend the paging coverage area. Optionally.
At the remote repeater/paging transmitter. Rx Disc O/P Enable jumpers JUT and/or JUT are closed and Data Regeneration jumper JU7 is in the B (Enabled) position, allowing the discriminated data signal to be routed from B10/C28 to U16d where it is amplified to TTL levels. The regenerated data is converted to RS-232 levels through driver/receiver U3, is routed through Data Select Jumper JUN-B (RAPT DATA I/P) and then follows the normal data path through U3 to Bull.
3. ALIGNMENT PROCEDURE AND INSTALLATION 31 General The CI-PM-3 Paging Modulator is by default configured for stand-alone base station paging. using 2-Level paging data with a binary polarity of 1, and using the on-board PPM 10 MHz COCCYX. Table 4-4 contains a complete list of CI-PM-3 default jumper settings. The CI-PM-3 can also be configured for 4-level signal (base transmitter only) paging, remote paging, link repeater or higher stability operation.
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 sub rack (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 Sub rack. Allow approximately 5 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.
3.7 Reference (Analog Paging) Adjustment C-PM-3 Reference frequency adjustment is factory set. It is strongly recommended that they not be altered. The following procedure applies only if field adjustment is required. 1. Ensure shunt jumper JUN-A is installed. Set front panel DB-15 connector J1 Pin 4 to ground (J1 Pin 8) and J1 Pin 5 to open (no connection). 2. Monitor the Communications Test Set and adjust REF ADJ potentiate R24 for the transmitter operating frequency +/-1 Hz. 3.
7. Set SW3 (SET MOD) to 2 LEVEL. Set SW4 (SET DEV) to the center position. Adjust R23 (BP DEV ADJ) for maximum deviation of kHz. 3.10 PLL Setup CI-PM-3 PLL adjustments are factory set. It is strongly recommended that they not be altered. The following procedure applies only if field adjustment is required: I. Install Power Enable surface-mount jumpers JUT and JUT. 2. Ensure front panel SW1 (FREQ REF) is set to EXT. and shunt jumper JUN-A is removed.
6. Set Trigger Slope to negative. 7. Continue monitoring the data signal at TP9 on channel 1 of the oscilloscope while monitoring the period of the data delay pulse at TP7 on channel 2. 8. Adjust R95, DELAY SYNC, until the period of the data delay pulse measured at TP7 is identical to that measured in step (b) above. T the delay resolution C: flammable inter U22) 9. With shunt jumpers JURUA, JURUA and JU33A installed, monitor the frequency of the signal at TPS. 10.
For the Simulcast system depicted in Figure 5-2. the signal transmitted by PAGING TX #1 will not be delayed. as this is the furthest site from the BASE TX. However. to ensure identical signal processing characteristics at each site, the DATA DELAY circuitry of the CI-PM-3 at PAGING TX #1 will be enabled. but with zero delay selected. PAGING TX #2 will have its paging signal delayed by a value proportional to the difference in distance between PAGING TX #1 and PAGING TX #2 to the BASE TX.
3.13 Repeater Configuration The CI-PM-3 modules at both the base transmitter and paging/repeater must be configured individually. Individual setup procedures must also be followed for analog/digital paging and for digital-only paging. Note: The CI-PM-3 modules must be set for 2-level signal operation only when configured for use in a paging repeater system. 3.13.1 Base Transmitter Site CI-PM-3 Configuration The setup instructions of sections 3.5 through 3.
