Monitor connections
Connect the unit to the monitors using 75-ohm video coaxial cables with BNC
connectors. The unit provides a 1Vpp CVBS signal.
If the monitor has a loop-through connection and you are not using the loop-
through output, then select the 75-ohm impedance setting on the monitor. If the
monitor's loop-through output is connected to an additional device, the device's
termination is set to 75 ohms and the monitor's termination is set to high
impedance. (Note that this is not necessary on devices with automatic
termination.)

Console port connection
The serial RS232 console port connector is used to connect a PC to the unit for
configuration or service purposes. Use a null-modem cable to connect the serial
port of the PC to the unit. The Baud rate can be selected in the menu system.
The serial RS232 console port connector is also used to connect Bosch D9000
series control panels via an interface unit for Divar alarm activation. Alarm
input mapping can be set up in the menu system.
