MODEL 210-01 CATV AUDIO/DATA DEMODULATOR SECTION 1 GENERAL 1.1 Equipment Description - The Series 210-01 operates with standard CATV cable systems to provide a paging system by receiving the paging audio signal and a data control signal which determines if the paging message is intended for the location it is programmed for. Detected data is decoded to determine if the audio is intended for this location as determined by the location code selected by two BCD switches on the front panel.

2.0 Installation 2.1 Mechanical - The 210-01 is packaged in an aluminum extrusion. The -R option is mounted on a 1 3/4” X 19” panel that can be mounted to a rack using the 4 holes at the ends. It derives +DC from the wall power supply (+12V unregulated). See Figure 2.1.

2.4 Installation / Operation 2.4.1 Installing and Operating the 210-01(Figures 2.1 to 2.3) 1.) Place the 210-01 where desired. (Attach four rubber feet if desired.) 2.) For the -R rack mount option mount the 1 3/4” panel to a rack using the four end screws on the rack panel. 3.) Connect the wall power supply to 115 VAC, 60 Hz and the power supply 2.1 mm DC connector to the 210-01 (Figure 2.1) 4.) Observe that green power LED (DS1) is illuminated. 5.

3.2 Command Code Description - The 210-01 demodulates a multiplexed audio channel and data channel. The audio channel delivers a voice paging. The data channel provides addressable control information. The 210-01 utilizes a Microchip 16C63 processor to receive and process control data, and to control the audio switch. 3.2.1 Command Stream - The command stream is provided as an Asynchronous RS232 data channel, running at 9600 baud, with NO parity, 8 bits/character, and 1 stop bit.
