Up to three tuners can be daisy-chained from one RS-232 control port. Remember that you will need
to use the Unit# address in your programming when you control more than one tuner from the
same control port. You can also daisy-chain one or two tuners with an AV6x4 A/V Router. In this
application, set the Router to the lowest Unit#.
