6Serial Communications

To interface the VHD Controller 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 3-14.

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 19200, to match that of the VHD Controller RS-232 port.

RS-232 Connection and Port Configuration

Serial commands to the VHD Controller take the following form:

•Commands are not case-sensitive.

•For a single command that takes no parameters, type the command followed by a carriage return; for example, to set the aspect ratio to Letterbox, type

LETTERBOX <Enter>.

•For a single command that takes a parameter, type the command, a space or a comma and the desired value followed by a carriage return; for example, to set the brightness to

-10, type BRIGHTNESS -10 <Enter> or BRIGHTNESS,-10 <Enter>.

•You can also send a string of multiple commands on a single line, separated by commas. For example, COMPOSITE,BRIGHTNESS 100,ANAMORPHIC <Enter> switches to the Composite video input, sets the brightness to 100 and sets the aspect ratio to Anamorphic. Command strings can be up to 255 characters long.

Avoid combining the ON or POWER 1 commands with other commands on a Note single line. After sending ON or POWER 1, allow at least 15 seconds for the VHD Controller to power up. Once it does, it will accept and properly execute

multiple serial commands.

Table 6-1lists the RS-232 command set. The “Parameter (min/max)” column shows the valid parameter ranges, or “NA” for commands that take no parameters.

When you enter a valid command, the VHD Controller executes it and acknowledges it with a plus sign on the command line (+ >). When you enter an invalid command – one that is misspelled or followed by values outside the valid range for that command – the VHD Controller ignores it and returns a minus sign (- >).
