Two transmitters can work as a 32 channels
distribution system. The transmitter can be operated in
serial mode to loop-through the IR radiator signals
from a master transmitter. One of the six radiator
outputs of the master transmitter is connected with an
RG59 cable to the radiator signal loop-through input
of the serial transmitter. The Transmission mode of the
serial transmitter must be set to ‘Serial’.
