Only one mode can be used at the same time: Control mode, or Pass-through mode, or Command Injection
mode. If you choose one of them, TPS serial link and local RS-232 port will operate in the same mode.
Pass-through Mode
In pass-through mode, the given device forwards the data that is coming from one of its ports to another same
type of port. The command is not processed by the CPU. Incoming serial data is forwarded from TPS input port
to local RS-232 port and vica versa inside the receiver.

Command Injection Mode
In this mode, the receiver works as an RS-232 bidirectional converter. The TPS signal is converted to RS-232

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 receiver through the TPS transmitter and is able to remote
control the projector via RS-232.
