CONNECTING A RELAY OUTPUT
The DX4104 provides a single terminal block for connecting one relay device. The relay output is not programmable; 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 DX4104 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.

CONNECTING THE MAIN MONITOR
The DX4104 supports either an analog or a VGA main monitor. Connect one of the following monitors to the unit:
• Analog Monitor: Connect the monitor to the MAIN OUT connector. Use a 75-ohm video coaxial cable with BNC connectors. Then set the
first S/W switch to the up position (TV).
• VGA Monitor: Connect the monitor to the VGA connector. Use a 15-pin VGA monitor cable. Then set the first S/W switch to the down
position (VGA).
CONNECTING THE SPOT MONITOR
The DX4104 supports one optional analog spot monitor. You can configure the monitor to display individual video channels or a sequence of
video channels.
Connect the optional spot monitor to the SPOT OUT connector on the rear panel. Use a 75-ohm video coaxial cable with BNC connectors.
