6.1
RS-232 Connection
and Port Configuration To interface the PlasmaWall with a home theater automation/control system or a PC
running terminal emulation software, connect it to the RS-232 output of the DHD
Controller as shown in Figure 3-4. Connect your control system or PC to the RS-232 input
of the DHD Controller as shown in Figure 3-9.
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 DHD Controller
RS-232 port.
6.2
Serial Command
Syntax Serial commands to the DHD 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 <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 DHD 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
DHD Controller ignores it and returns a minus sign (- >).
