6.4.1 Connecting the RS-232 Control Interface
You can connect several switchers (from the series of 32x32 or 16x16 matrix
switchers) and the control unit in an RS-232 daisy chain arrangement, with or
without using a Null-modem adapter, as Figure 7 illustrates.
The RS-232 daisy chain switcher arrangement is transparent. This lets you arrange
the switchers (from the series of 32x32 or 16x16 matrix switchers) according to
your requirements, and not according to a fixed sequence dependent on the
Machine #.
