Use the Model 2181 IR Coupler to send IR control signals from one DA-550 or DA-8200 to another DA-550 or DA-8200. Using a master DA-550 or DA-8200 and adding up to eight slave units, IR control signals will not be passed from master units to the slave units unless a Model 2181 is used at each slave DA-550 or DA-8200 panel. The Model 2181 allows each TV with a target that is connected to the slave unit, to send IR signals back to the audio/video devices connected to the master DA-550 or DA-8200.
The Model 2181 can also be used to send IR signals to modulators connected to the A input on a DA-550 or DA-8200 panel. IR normally passes only through the B input but using the Model 2181 in reverse position and connecting the green hot wire to the DA-550 or DA-8200 panel the DA-550, DA-8200 or SVM series modulator will receive all IR signals.
