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 3-8
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.
