PROTOCOL
MV16P-30
This video switcher interface is used for systems with single Monitor with multiple multiplexers with 16
cameras on each multiplexer.
The Network Address of the DNA200 is programmed for the Masterstation/DAD104 using the video monitor. This
programming is done in the DXC901 or DXC910. No configuration is required for the sub stations with camera in
the DXC901/DXC910.
The camera address for each call number is programmed in the DNA200 (see Configuration).
The camera address is a 4 digit number. The first 2 digits are used to define the multiplexer (01-16) and the last
2 digits are used to define the camera (01-16) connected to the multiplexer.
Example: Camera address 0112 is programmed in configuration for one of the intercom call numbers.
This camera is now assigned to multiplexer 1 input 12
COMMUNICATION PROTOCOL
The device receiving from the DNA200 is setup in the following matter:
The interface is using RS232 between the baud rates of 1200-19200 bps (see S ETTING B AUD R ATE /D EVICE
