Command Injection Mode
Block diagram of the serial interface in command injection mode
In this mode, the receiver works as an RS-232 bidirectional converter. The TPS signal is converted to RS-232
dataandviceversa.TCP/IPportnumbersaredefinedfortheserialports(TPSandlocal)forthispurpose.
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.
RS-232 Signal Transmission – Example
The Concept
The System controller can send commands to the receiver through the TPS transmitter and is able to remote
control the projector via RS-232.
