6.1
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 3-7.
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; the default
baud rate is 115200.
6.2
Serial Command Syntax
Table 6-1 lists the RS-232 command set. All commands are in ASCII format. 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, the DView ignores it and returns
-N/A
instead
of the four-digit code.
