MATRIX SWITCHERS
13
[ERR], just the version number; for example
[3.2] or [3.5].
[VISn]
n = 1 Enable VIS
n = 0 Disable VIS
This command enables or disables vertical
interval switching, if the option is installed on
the HOMERUN Matrix Switcher.
7.2.3 CONTROL COMMANDS
These control commands are used for
controlling the switcher. They can be part of a
normal program to operate the switcher. These
command actions are lost if power is
disconnected from the unit, or if the unit is
reset in any way.
[xxxxxF] - Send feedback.
Adding F at the end of any command will
provide feedback in the form of [OK] or [ERR].
Otherwise there will be no feedback, except
with the [VERN] command.
[UIDn]
n = Unit ID number. It could be any
number from 1 to 9.
This command sets the unit ID number. A total
of up to 10 unit ID’s can be assigned to
HOMERUN modules, using ASCII code, for
individual control of each unit. Additional units
can be controlled using hex codes.
If n=1, the switcher listens to all commands. If
n=0, the switcher does not listen to any
command.
Table 3 provides the relation between the Unit
ID number and the LED’s on the back panel of
the unit. In other words, once an ID number is
assigned to any module through an RS-232
command or the Front Panel, this module can
be identified by the illuminated LED’s located
on the back panel switcher.

Table 3 Unit ID LED's of Back Panel
The Unit ID command will allow only units with
the same ID number to respond to any
RS–232 commands. This command allows
independent switching of various modules.
When independent switching of various
modules is required first issue the [UID1]
command to make all modules respond to
common commands. Then issue different
[UIDn] commands to each group of switchers
to communicate with particular modules. The
[UIDn] command only should be issued once
prior to communicating with the individual
modules.
[UIDnE]
n = Unit ID number 2 to 9
This command selects the exclusive switcher
level to control. The level is controlled based
on the Unit ID number-n. The default during
power-on is set to Unit ID 1 regardless of the
actual ID number on the unit. This means that
all units (levels) will be controlled
simultaneously after power on. This command
disables all units except the one in the
