7.5.1 Setting the Machine #
To control a unit remotely via RS-232, RS-485, IR or the Ethernet, each unit
has to be identified via its unique Machine #. Set the Machine #
1
on a
VS-3232A
unit according to
Table 7
.

7.6 Connecting a Control Interface
You can connect a control interface (RS-232 or RS-485). It is recommended
that the control interfaces are identical on each switcher in the series of 32x32
matrix switchers; either RS-232 or RS-485 (one control interface suffices).
For example, in an interconnected varied-format 32x32 switcher application,
if the switcher that connects to the PC connects via the RS-232 control
interface, each switcher would interconnect via the RS-232 control interface
and not via the RS-485 control interface.
You may transfer from one interface to another via the Kramer
VP-43xl
Interface Converter

. You can choose the RS-232 control interface, if the
range is less than 25 meters for each point-to-point connection.
For greater ranges, you can choose the RS-485 control interface, and operate
the switcher from an extended distance of up to 1000 meters.
7.6.1 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 15
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 #.
1 When using a single unit, set the unit to MACHINE # 1
