Figure 6-4. Infra crosspoint
Example
Above screenshot shows an Infra crosspoint layout of a MODEX assembled with MODEX-
IF-RS232-IR module. Local IR input signal is switched to the IR output port within the given
module
– and extended to the other MODEX as well.
Info: The signal of the local input port is always extended via the fiber optical cable, but the other
device’s Infra crosspoint settings determine if the incoming signal is switched to its IR
output port or not.
Further examples:
Example 1
IR signal received via fiber optical cable
is switched to the IR output port. Local IR
input signal is extended via fiber optical
cable.
Example 2
IR signal of local input port and IR signal
received via fiber cable are
mixed on
each other
and switched to the IR output
port. Local IR input signal is extended via
fiber optical cable.
Example 3
Only local IR input signal is transmitted
to the other extender.
6.3.4. Serial crosspoint
The number of the available ports in a unit is determined as follows:
Number of inputs = Number of the ports [local unit] + Number of the ports [remote unit]
Number of outputs = Number of the ports [local unit]
In crosspoint view every serial port appears as an input and an output. It means that Tx
data channel of the port is an input and Rx data channel is an output
– within one port.
All serial inputs are transmitted to the remote device all the time. As all serial ports data
can be transmitted via the link, the link does not appear as an output as it appears in video
or in audio crosspoints. The input port with a link icon symbolizes the input of the remote
side.
Info: The serial source switched to the local output can be selected on the local device.
