Cables and Wiring
●
When there are mulple cores in one parallel line, only one pair of closed cores are allowed to
transmit signal. It is not allowed to use
mulple pair of cores in one cable to transmit signal.
●
When using parallel lines, it is suggested to use those with shielding layer. If dual core or
mulple
core parallel lines without shielding layer are routed, stability of signal transmission can be
eected. You need to run a test before installaon.
●
Impedance of cable should not be over suggested value, or distributor cannot transmit enough
power to indoor staon or door staon.
●
Strong electricity and weak electricity cannot be wired in the same route, they need to be wired
separately and the distance should be more than 0.5 meter.
●
All the cables used need to follow the restricon in the following table.
