6Serial Communications

To interface the Vision 10/12 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 3-12.

Configure the RS-232 controller or PC serial port as follows: no parity, 8 data bits, 1 stop bit and no flow control. Set the baud rate to 9600, to match that of the Vision 10/12 RS-232 port.

RS-232 Connection and Port Configuration

Table 6-1lists the RS-232 command set. All commands are in ASCII format and must be in

UPPERCASE.

6.2

Serial Command Syntax

When you send a valid command, the Vision 10/12 executes it and acknowledges it with the first three characters of the command followed by “OK;” for example, RRAOK. When you send an invalid command, the Vision 10/12 ignores it and returns the first three characters of the command followed by “NG;” for example, RRXNG.

Notes:
1. All image quality settings must be made with the remote control. After the image adjustments are
complete, you can use these commands to store the settings in the selected memory.
2. The power on command (PON) will not provide an OK reply; it will instead reply with a random character.
For your automation system, simply ensure that you receive a character after the PON command. If you
do not get any reply after PON, send PON again.
