MATRIX SWITCHERS
14
1. The number of outputs must be the same
on all units to be looped.
2. Output offset is zero for all units.
3. The input offset must be set for all units
except for the first one. The offset for the
input should be the same as the last
number of the previous unit
4. The number of inputs available on the
second unit for a 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 the loop offset is the number of
outputs of the previous unit.
Example: If the user wants to create a 12x4
switcher, use two 8x4 matrix switchers.
Connect output 1 through 4 of the first unit to
the last four inputs of a second unit in
increasing order. Please program each MAX
Switcher individually using the following table:
PARAMETER UNIT A UNIT B
Size [I08O04S] [I08O04S]
Offset [I00O00A] [I08O00A]
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
[16O04] 16 - 4 16 - 4
[17O01] NONE –1 1 - 1
[128O04] NONE – 4 12 - 4
[129O03] NONE - 3 NONE - 3
[SDELnn]
nn - value from 00 to 99, Sync delay
time in multiple of 65 ms.
This command sets Sync delay time in 65ms
increments. The sync delay can be set to a
minimum of none or to a maximum of 6.4
seconds. The sync delay function is useful to
avoid an unwanted image (a glitch) that
appears on the projector or monitor screen
when switching between different sources of
different signal resolutions. Typically, a 0.5
seconds delay will clean up the image on most
of the displays during the switching. Keep in
mind that making the sync delay too long will
require the user to wait before implementing
the next command until the prior command is
executed. When specifying sync delay, capital
letters A through F also can be used to get a
longer delay. For example, [SDELFF] will
provide almost 19 seconds of delay.
n=00 corresponds to no Sync delay
n=08 corresponds to 0.5 second delay
n=38 corresponds to 2.5 second delay.
n=99 will set Sync delay of 6.4 second
[VERN] - Version
This command will return the current version of
the firmware used on the switcher. It does not
require the feedback command to return the
feedback. For example if [VERN] is typed, the
feedback of [3.2] will return from the MAX
switcher.
