3. Product Overview UMX-TPS-TX100 series – User's Manual 33
Control Mode
The incoming data from the given port is processed and interpreted by the CPU. The mode allows to control
setting.
Command Injection Mode
In this mode, the transmitter works as an RS-232 bidirectional converter. The TPS signal is converted to
purpose. E.g. the default Command Injection port number of the local RS-232 port is 8001. If a command
is coming from the TPS interface which addresses to the port no. 8001, it will be transmitted to the Tx pin
of the local RS-232 port. That works in the opposite direction of course and the method is the same on the
serial interface of the TPS port as well.
The Concept
The System controller can send commands to the transmitter and it is able to remote control the projector
through the TPS receiver via RS-232.
Settings
▪ System controller: wireless IP connection to the same Ethernet as the transmitter is connected to. Use
certain IP:port address.
▪ Transmitter: set the RS-232 mode to Command Injection on TPS output port. Set the further parameters
transmit the RS-232 data toward the receiver.
▪ Receiver: set the RS-232 mode to Pass-through on RS-232 port.
▪ Projector
cable with the proper wiring.

RS-232 Recognizer
(delimiter) is arrived or the timeout elapsed after the last data. The last incoming serial data is stored and it
can trigger an action in Event Manager.
RS-232 Recognizer Example
UMX-TPS-TX140-Plus has an active video signal, the transmitter login the VC codec automatically. In
this case the RS-232 operation mode of the TPS receiver needs to be set to Pass-through.
communication with the VC codec via RS-232:
Î UMX-TPS-TX140-Plus (starts the communication on TPS RS-232): PING
Í VC codec (requests the login name): Login name:
Î UMX-TPS-TX140-Plus (sends the login name): Admin
Í VC codec (requests the password): Password:
Î UMX-TPS-TX140-Plus (sends the password): Admin
The RS-232 recognizer settings has to be done with Lightware Device Controller Software (see details
in see Message Recognizer RS-232
Recognizer section).
Create the following events in the Event Manager:
E1.PING' on P2 port of
TPS RS-232 to the VC codec over the TPS receiver. For more details see Sending a Message (ASCII-format)
via Serial Port section.
E2. Set a condition where Login name: is the recognized RS-232 message. Action is sending serial message
('Admin') on the P2 port to the VC codec.
E3. Set a condition where Password: is the recognized RS-232 message. Action is sending serial message
('Admin') on the P2 port to the VC codec.
For more information about setting the events, see Event Manager section.
