Serial Communications, Serial Command Syntax

6. Serial Communications

To interface the CinemaWall with a home theater automation/control system or a PC running terminal emulation software, connect it to your control system or PC as shown in Figure 3-13.

Configure the RS-232 controller or PC serial port as follows: no parity, 8 data bits, 1 stop bit and no flow control. Set its baud rate to 115200, to match that of the CinemaWall RS-232 port.

RS-232 Connection and Port Configuration

Serial commands to the CinemaWall take the following form:

•You can send commands in either hexadecimal or ASCII format.

•ASCII commands are not case-sensitive.

•Commands begin with the “Start of Text” (STX) character (02h or <Ctrl> B in ASCII), followed by the display ID (2 bytes), the command data and command argument

(3 or 6 bytes; refer to Table 6-1)and the “End of Text” (ETX) character (03h or <Ctrl> C in ASCII).

•You do not need to send a carriage return after the command.

•The default CinemaWall display ID is 01 (30h 31h). With most commands, you can also use the “wildcard” display ID of “**” (2Ah 2Ah) in place of any value for the ID. However, when requesting status via serial commands, you must use a specific display ID; “**” does not work in these cases.

For example, if the CinemaWall ID number is set to its default value (01 = 30h 31h), send the following sequence to set the contrast to its highest possible level (255):

	STX	ID (2 bytes)		Command (3 bytes)	Argument (3 bytes)	ETX

		30	31
Hex	02	or		43 4E 54	32 35 35	03
		2A	2A

		0	1
ASCII	<Ctrl> B	or		C N T	2 5 5	<Ctrl> C
