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 .
• 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 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 (- >).
