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 3-11.
(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.
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.
