Preset Settings - Lightware MODEX-OPTS-TX User Manual

If an input is switched to an output, and both the input and the output belongs to the same
serial port connector, that results an internal loopback. This way the serial link can be tested
between the source and the MODEX extender device.
Example
The working method is the same as for Infra crosspoint settings.
Above screenshot was made about a Serial crosspoint layout of a MODEX (assembled
with MODEX-IF-RS232-IR module). Local UART input signal (on Rx data lane) and the
signal received via fiber optical cable are switched to the UART output port (Tx data lane)
within the given module. Local UART input signal is extended also to the other MODEX.
Info: The signal of the local input port is always extended via the fiber optical cable, but the other
device's Serial crosspoint settings determine if the incoming signal is switched to its UART
output port or not.
Further examples:

7.4.5. Preset settings

Each MODEX extender has eight preset memories that can be used to store settings and
configurations of the MODEX. Click on the Presets button in the right top corner to display
the Presets window.
Info: A preset setting stores the full configuration of all modules, ports and system settings. EDID
data is not stored, but the ID number of the emulated EDID is saved – for every input port.

Signal received on local UART port (Rx
data lane) is switched to the Tx data lane
of the port and extended to the other
MODEX as well.
