CONNECTING A RELAY OUTPUT
The unit provides a single terminal block for connecting up to four relay devices. The relay output is not configurable; it operates as a normally
open circuit. A signal from the relay output will operate the relay device. The maximum relay power rating is 0.3 A at 125 VAC or 1 A at 30 VDC.
For information about configuring the relay output, refer to the DX4700/DX4800 Series Server Operation/Configuration manual.
NOTE: If the electric current in the relay circuit exceeds the maximum power rating, the unit can be damaged.
To connect a relay device:
1. Using a small screwdriver (or similar tool), push in the OUT wire retainer (1) on the terminal block.
2. Insert one wire from the relay device into the retainer.
3. Push in the ground wire retainer (G) on the terminal block.
4. Insert the ground wire from the relay device into the retainer.

• Analog Monitor: Connect the monitor to the MAIN OUT connector. Use a 75-ohm video coaxial cable with BNC connectors.
• VGA Monitor: Connect the monitor to the VGA connector. Use a 15-pin VGA monitor cable.
CONNECTING THE SPOT MONITOR
The DX4700/DX4800 also supports the connection of both an analog spot monitor and a VGA monitor simultaneously. The spot monitor can be
configured to display individual video channels or a sequence of video channels.
