NetMedia TUNER User Manual

Standard TV Sequencing Tuner
NM-TUNER
The NetMedia TUNER demodulates one or more analog standard definition channels and outputs a single static or sequencing composite audio/video signal. Once demodulated, the selected channel(s) can be input into monitors, multiplexers, quads, DVR’s, or any composite A/V device including HD and digital TV’s. This provides convenient viewing access to modulated security cameras or analog antenna and cable TV signals.
Product Includes:
1. Tuner Assembly (Video Output Connector, 2 - Audio Output Connectors, RF Input Connector, Power Input Connector, End Plate, DIP Switches, Save Button, CABLE/AIR Switch, Power LED).
2. 12V DC 300mA Power Transformer (Center Conductor Positive).

Installation Procedures:
1. Connect a video device to the tuner’s RCA Video Output Connector. Adapter’s such as BNC to RCA may be used as necessary. If audio is available, connect the tuner’s monaural Audio Output Connectors to the output device.
2. Connect the coax cable from a modulated camera or distribution system to the tuner’s RF Input Connector.
3. Remove the End Plate from the tuner assembly and select a channel with the DIP Switches as shown in Figure 1. For VHF/UHF antenna channels 2-83, move the CABLE/AIR Switch to AIR. For cable channels 2-135, move the CABLE/AIR Switch to CABLE. Note: the CABLE/AIR switch labels may be reversed (AIR/CABLE).
4. If sequencing from multiple channels then connect power to the unit. Press the Save Button to enter the current channel into memory. Select and Save all desired channels. When finished, move the CABLE/AIR switch to AIR (if not already on AIR) and set the DIP Switches for the dwell time in 1/10 second intervals as shown in Figure 1. To erase the last channel, set all switches OFF and press the Save Button once for every setting to remove. To erase all channels and reset the unit, press and hold the Save Button while applying power.
5. Replace the End Plate and connect the 12V DC 300mA power supply to the Power Connector and an AC outlet.
