6Serial Communications

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.

6.1

RS-232 Connection and Port Configuration

Table 6-1lists 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/Ainstead of the four-digit code.
