When using RS485 serial connection, the max. in one serial connection is to connect up to 32 pieces of
speed dome, if over 32 pieces of speed dome, then please use “RS485 Aster Connection” method together
with our WH-810 (8 port RS485 distributor) to diversify the number of speed dome in one single serial
connection, in order to make sure the stability of the complete control system.
2. RS485 aster Connection
This is the most common method in practical installation work. In the aster connection, if a RS485
distributor is not utilized, it is likely to have reflected signal and to lower the ability of resisting
interference. This may cause mal functioning of the control signal that results in faulty control of the
camera or unstopping operation when the control signal is stopped.
In such cases, we recommend to use our WH-810 RS485 Distributor. This product can effectively convert
the aster connection into the correct connection method that meets RS485 requirements to acquire optimal
communication reliability. See the following diagram for reference.
