Troubleshooting
The following Q & A section, “Frequently Asked Questions”, is composed of
questions and answers to typical problems and situations encountered by users
of the Matrix 200. We hope that the information will be both helpful and
informative during your implementation of the Matrix 200.
Frequently Asked Questions
Q: I have connected up the Matrix 200 and programmed it, but it is not passing all the signals.
What should I do?
A: Confirm that all the Matrix 200 input and output cable connections have been properly made. When
dealing with multiple inputs and outputs with several cables per input/output, it is very easy to incorrectly
route the wiring — yet, this is often the last item checked when troubleshooting. Possible wiring errors
include:
• Crisscrossing one wire of an input or output e.g., connecting the red wire of input number one to the
red connector of input number two instead.
• Running five wires to an input, but running four wires at the corresponding output.
• Reversing the horizontal and vertical sync wires.
Once the wiring has been rechecked, verify that the Matrix has been programmed correctly. Review the
programming instructions in the manual. In particular, double check that all input-output routing is correct.
Likewise, verify that the individual RGB planes are not being broken away — be sure that the RGB and
sync planes are switching together (if that is what is intended).
Keep in mind that the Extron supplied Windows based Matrix 200 control program can be used to verify
Matrix 200 settings. This is one of the best troubleshooting tools to use when working with the
Matrix 200
(other Extron Matrix switchers have similar programs). This program will graphically show all
current input-output ties along with the type of video signal (RGBHV, RGBS, Composite Video, etc.)
being programmed. It simplifies verifying input-output ties, presets, and audio settings.
The Extron Matrix control program is also useful for checking a third party controller’s programming code.
With the Extron control program, a desired tie can be made and the ASCII code will be displayed. This
information can then be used to verify that a third party controller has been programmed correctly.
Q: How can I control the Matrix 200?
A: The Matrix 200 can be controlled through the front panel, or through a third party controller via RS-232/
422, or through the Extron supplied Windows control program. It can also be controlled with various
terminal programs such as Windows Hyper Terminal.
The front panel will remain active if the unit is being controlled by RS-232/422 so the Matrix can take
commands from both sources.
Q: My Matrix 200 seems to be taking too long to switch, why is this?
A: Check the RGB to sync delay feature. This is a built in delay function which allows the video time to sync
up. It may be set too long, thus, causing the delay.
