The 6th DIP-Switch enables or disables the reception from IR remote control.

In ON position IR signal reception is enabled (default factory setting).

Note:

If the CASCADE function is enabled the three auxiliary functions are disabled,

except RGB Mute and Autoswitching can be activated by serial control (RS-232).

9.1 Control in CASCADE mode

In CASCADE mode a source can be selected by using the buttons on the front panel
of each unit or using a external serial controller.

For RS-232 control of the cascaded units all the pins#12 (Tx) of all units must be
joined together and connected to the serial controller, the same must be done with

all the pins #25 (Gnd).
For the serial codes see the table of commands in chapter 8.0.
