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
.
• 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
or
BRIGHTNESS,-10
.
• You can also send a string of multiple commands on a single line, separated by
commas. For example,
COMPOSITE,BRIGHTNESS 100,ANAMORPHIC
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 (- >).
