6.1
RS-232 Connection
and Port Configuration To interface the VX-2i 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
3-11.
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 VX-2i RS-232
port.
6.2
Serial Command
Syntax Serial commands to the VX-2i 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 <Return> .
• 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 <Return> or
BRIGHTNESS,-10 <Return> .
• You can also send a string of multiple commands on a single line, separated by
commas. For example, COMPOSITE,BRIGHTNESS 100,ANAMORPHIC <Return>
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.
Table 6-1 lists 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 VX-2i 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 VX-2i
ignores it and returns a minus sign (- >).
