Pass-Through Mode; Command Injection Mode - Lightware HDMI-TPS-TX210 User Manual

5.5.2. Pass-through mode

In pass-through mode the incoming data from the local and link sides is passed through to
the other side without processing it. The serial ports on the transmitter and on the receiver
are linked together through the CATx (TPS) cable. This allows direct communication
between a device connected to the receiver and a device connected to the transmitter.
Example
The transmitter is connected to a receiver. A button panel is connected to the RS-232 port
of the transmitter and a projector is connected to the RS-232 port of the receiver. The
commands sent by the button panel are passed through the extenders to the projector.
This layout allows to remote control the projector from a button panel.

5.5.3. Command injection mode

When the device is in RS-232 command injection mode, it works as an RS-232-Ethernet
converter (bidirectional). There are two separate TCP/IP ports for this purpose, one for the
link and one for the local side. On these ports the Ethernet packets are converted to RS-232
data and vica versa. The local and the link sides are not connected in this mode.
Example
The transmitter is connected to a receiver. A monitor is connected to the receiver's RS-232
port. The transmitter and a computer are connected to same Ethernet. In command
injection mode the computer can send commands to the monitor through the extenders, so
this layout allows to remote control the monitor from a computer.
