Vidikron VL-40 User Manual

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. 

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. 

• 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.
