Can I use
contact closure
to control the
switcher?
Contact closure cannot
control the MAX Switcher
directly, but this can be
done using the Altinex
CP7317RS unit, which is
capable of converting
contact closure control into
RS-232 commands. The
number of relays available
limits the number of
functions available.
9 Is the MAX
Series capable
of controlling
various
projectors?
Yes, windows based control
software is available to
allow easy control of the
MAX Series Switcher and
other devices connected to
the switcher. Please get it
from the Altinex website at
www.altinex.com in the
Download Section.

TROUBLESHOOTING GUIDE 10
First, make sure that power is connected to the
power-input connector and input power is within the
range of 90-260 VAC.
Make sure that cables are connected properly and
fit snugly. Please immediately replace any defective
or damaged cables.
If RS-232 connection is used to control the MAX
Series Switcher, then please make sure that the
connections to each pin of the RS-232 port located
on the back of the unit is as described in step 3 of
section 6.
In the video module, please make sure that the
input level of the video signal RGB is 1.2 V p-p. In
the audio module, the input level of the audio signal
is 5 V p-p.
If a control system is used to control the switcher
through an RS-232 port, make sure that there is at
least a 50 ms delay between two adjacent
commands being sent. Also make sure that all
commands have a square bracket ‘[‘ before and “]”
after each command if the code is set to 1.
Please verify that a correct ID number is assigned
to each unit. If a particular group of modules need
to be controlled then the unit ID number must be
the same for all the modules in that group. The unit
ID number 0 will make the MAX unit not respond to
any command, while unit ID number 1 in the
command will have all units follow the command.
When any Input or Output LED is flashing, please
do not use the SAVE, RECALL, or RESET function.

lights blink and confirmation is given through an
audible beep.
To use the RECALL function, make sure no INPUT
or OUTPUT LED is flashing and then press the
RECALL button until all lights on memory 1 through
