For certain installations, multiple-control structure might be required. You can setup the keyboard to
Master / Slave mode in order to work with more than 1 keyboard simultanously. In this operation
mode, all keyboards have to be connected in a chain, with RS-485-1 for output and RS-485-2 as
input ports. The keyboard that is nearst to the devices has the highest priority.
