Cable length to the IR receiver unit L1=L2+L3+M1
Difference in length among L1, L2+L3+M1 should be /-3 meters
Distance from IR receiver unit to IR main unit should be less than 100 meters or more
than 2 meters L1=L2+L3+L4≤100M L1=L2+L3+L4≥2M
* BNC connector installation method
Because the interconnection coaxial cable (50Ω) of IR receiver unit is used for transmit IR
signal and IR receiver power (DC12V), please make sure the circuit not shorted between
IR signal and power when install the IR receiver, or it will burned out the fuse (0.5A) of IR
receiver unit on the rear panel of IR main unit.
a .Please stripping the coaxial cable (50Ω) outer, shield net and insulating layer with
above sketch map
b .Insert the wire and connect to the center pin,
soldering it
c . Insert the shield net and insulating layer to screw nut connector.
d .Connect ferrule to the screw nut connector’s
anti-shedding position
e. Fasten it with plier
