Riser shunt
323003 - riser shunt
The riser shunt is used to connect the riser BUS and system
BUS in order to separate BUS, transfer signal and switch
between video and audio channels . The device has five Rj45
connectors, which are for riser BUS input/ output, system
BUS input/ output . The last Rj45 and two other connectors
are designed to connect the riser system to the main power
supply . The device also has 2 4-gear video gain DIP switches
for video channel from the EP to the system BUS, and video
channel from the system BUS to the HANDSET . The video
transfer distance can be increased by adjusting the gain . By
installing several items 323003 in cascade, the riser systems
can be connected as a network and managed as districts .
The following table indicates the video amplifying gains .
During the installation, the parameters need to be adjusted
according to image requirements .

system conFiguration instructions
The system configuration for the Riser Shunt consists in
assigning a number to item 323003, setting the address
range managed by item 323003, and selecting the system
configuration mode . Only if the configuration is correct can
the system work correctly . There are 3 configuration methods .
The configurator alternative enjoys the highest priority . If the
physical configurator is used on the Riser shunt, then the
other configuration methods will be ineffective .
Note: if use physical configurator method is used, the power of item 323003 should
disconnected after the configurator has been installed, and then reconnected to
activate the configuration.
