4. If the monitor is touch-sensitive, it is recommended that you calibrate it before you use it. For information
about how to calibrate the monitor, please refer to the monitor’s documentation.
Connecting a Switch
If you wish, you can connect a switch to the unit to change the display on the monitor. The switch must be
connected to the In1 connector. For additional information, see Connecting Sensors, page 16, and refer to the
Embedded Video Gateway System Guide.
Connecting Multiple Monitors
If you wish, you can connect multiple CCTV monitors to the CVG-M. For example, you may wish to have one
monitor beside the driver’s seat and another beside the conductor’s seat.
To connect multiple monitors, you must use video splitters to split the connection. Bear in mind, however, that the
image quality in each of the monitors will be slightly degraded. To correct this problem, you can use a video
amplifier (booster) for each monitor. To ensure you have the correct equipment, consult a video equipment supplier.
