RS-232 Connection and
Port Configuration
To interface the DView 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 3-10.
(Use a straight-through cable.)
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 match that of the DView RS-232 port. To check the
baud rate setting, select
Baud Rate from the ISF Calibration menu (refer to page 41).
6.2
Serial Command Syntax
Commands are in ASCII format and are not case-sensitive.
A carriage return is not required after a command.
When you send a valid command, the DView executes it and acknowledges it with a
right-bracket character (]) followed by the four-digit numeric code you sent; for example,
]0002.
When you send an invalid command (one followed by values outside the valid range for
that command), the DView ignores it and returns >MAX or <MIN instead of the four-digit
code.
When you send an unrecognized/misspelled command, the DView ignores it and returns
-N/A instead of the four-digit code.
Table 6-1 lists the RS-232 command set.
