MATRIX SWITCHERS

2. Output offset is zero for both units.
3. The input offset must be set for all units
except the first one. The offset for input
should be the same as the last input
number of the previous unit.
4. The number of inputs available on second
unit for direct connection is the difference
between the maximum number of inputs of
the second unit, and the number of looped
outputs.
5. Set the loop offset separately for each unit.
The loop offset is zero for the first unit. For
other units it is the number of outputs of the
previous unit.
Example: If one wants to create a 28x4
switcher, there is a need for 2 16x4 HOMERUN
Switchers. Connect output 1 through 4 of the
first unit to the last four inputs of a second unit
in increasing order. Please program the
switcher using the following table:
PARAMETER UNIT A UNIT B
Size [I16O04S] [I16O04S]
Offset [I00O00A] [I16O00A]
Loop Command [I00O00L] [I00O04L]
Now if you send the commands as follows, the
active connectors will be as follows on both
units:
COMMAND UNIT A
Connection
UNIT B
Connection
[I02O02] 2 – 2 14 – 2
[I09O04] 9 – 4 16 - 4
[I16O04] 16 - 4 16 – 4
[I17O01] NONE – 1 1 – 1
[I28O04] NONE – 4 12 – 4
[I29O03] NONE – 3 NONE – 3
[RSET] - Reset Switcher
This command initializes all outputs (clears all
current connections of inputs to outputs), and
recalls memory #1 to switch appropriate inputs
to outputs, as saved in memory position #1.
There is no feedback provided, but the unit will
beep after execution of this command. This
command is the equivalent of turning ON the
unit.
[RSETD] – Default Reset switcher
This command initializes all functions, clears all
memories, sets baud rate to 2400, sets the
number of input/outputs to 16, resets offset to
00, and recalls memory #1 to switch the
appropriate inputs to outputs. There is no RS-
232 command feedback provided, but the unit
beeps after execution of this command. This
command resets the HOMERUN Switcher to
the same as the factory condition.
[RSETC] - Configuration Reset of switcher
This command initializes only the number of
inputs to outputs and offset to factory condition
default. There is no RS-232 command
feedback provided, but the unit beeps until this
command is executed.
[RSETS] - System Reset switcher
This command initializes everything except the
number of inputs, outputs and the offset. This
command initializes all functions, clears current
input to output connections changes baud rate
to 2400bps and clears all current memories.
There is no feedback provided, but the unit
beeps until this command is executed.
[VERN] – Version
This command provides the current version of
the firmware used in connected switchers.
There is no need to add an F at the end of the
command. There is no feedback of [OK] or
