- Connect the RS-232C input jack to an external control device (such as a computer or an A/V control system)
and control the Monitor’s functions externally.
- Connect the serial port of the control device to the RS-232C jack on the Monitor back panel.
- RS-232C connection cables are not supplied with the Monitor.
This chapter describes a subset of the Zenith standard MPI protocol. It differs from the standard
MPI communications protocol in terms of not requiring a continuous polling loop and only imple-
menting a subset of commands and responses.
Command format is as follows:
Command byte, optional data byte, optional data byte,...., checksum. All values in hex, no spaces,
carriage returns or line feeds. The checksum is the sum of all previous bytes in the command string,
truncated to 8 bits. If a command is received with a bad checksum, it should be ignored. If the
beginning of a command is received, the entire command must be received within some timeout
period. If the timeout expires, the partial command is abandoned, and any internal buffers flushed.
Response Format: Response, Data byte, Checksum
Commands Supported
Commands Supported
01. Power On
- To turn the power of the TV on, the following string needs to be sent to the unit;
E1 : It is the start of the command and signifies a “key” (as in front panel keys) command.
10 : It is the command for power on.
F1 : It is the checksum calculated by adding “E1” + “10” to get “F1”.
The unit will perform the action and will not return a response.
