Non-DGX Matrix Switcher Routing Behavior
Corrupted or Lost RS-232 Data

The RS-232 connection on the modules requires management of the RS-232 data line in
relation to switching operations. In an upstream matrix switching scenario, we recommend
that RS-232 control commands (via the DGX RS-232 data connection) are not sent
immediately prior, during, or subsequent to a matrix switching command. It is possible for the
RS-232 data to be corrupted or lost as the video (or audio) signal is removed and then restored
by the matrix switcher. The corrupted data could be misinterpreted by the destination
equipment.
Non-DGX Matrix Switcher between DGX TX and RX Pairs (FIG. 12 on page 24)

For best results when using a non-DGX matrix switcher between pairs of DGX TX and
DGX RX modules, place the upstream DGX RX module in Bypass mode. This will maintain
the video resolution/format that is fed to the DGX TX module after the switch rather than
trying to scale it to the matrix switcher’s preferred EDID timing.

When using a matrix switcher with a DVI board between pairs of DGX DVI TX and RX
modules, cycling power to the RX upstream from a DVI input on the switcher can cause an
image shift to the left. To resolve this issue, connect the DVI cable on the downstream
DGX DVI RX or cycle through the display’s source options.
Non-DGX Matrix Switcher with DVI Output and Downstream DGX TX

When a DVI output is connected to a DGX DVI TX, switching input video formats can cause
the new content to display briefly at the new resolution, to blink, then finally to stabilize on
the new content. This behavior only occurs on some monitors.
Non-DGX Matrix Switcher Routing Digital Audio Breakaway

When using an upstream non-DGX matrix switcher for digital audio breakaway (especially on
different digital formats), control operations can cause small audio “pops” or “crackles” on
both the analog and digital outputs of the DGX RX.
Technical Support
Before contacting technical support with a question, please consult this manual. If you still have
questions, contact your AMX representative or technical support. Have the serial numbers for the
modules and the splash screen information ready.
Note:
You may also be asked to take certain actions with the system and provide the resulting live
status update messages that appear in your terminal emulation program (e.g., TeraTerm, PuTTY, or
HyperTerminal). For more information, see page 63.
Serial Numbers
We recommend recording the serial numbers in an easily accessible location.
Splash Screen Information
A terminal emulation program (e.g., TeraTerm, PuTTY, or HyperTerminal) can be used to display
information, including the firmware version, on a module.
To obtain the splash screen information:
1. Open a terminal emulation program on the PC.
2.
Connect the PC to the TX or the RX via the USB mini-B port (a virtual COM port must be
established; see page 67).
