Planar PD520 Serial Communications, RS-232 Connection and Port Configuration, Command Description

Serial Communications

To interface the PD520 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 3-9.(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 PD520 RS-232 port. To check the baud rate setting, select Baud Rate from the Installer menu (refer to page 39).

RS-232 Connection and Port Configuration

•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 PD520 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 PD520 ignores it and returns >MAX or <MIN instead of the four-digit code.

•When you send an unrecognized/misspelled command, the PD520 ignores it and returns -N/Ainstead of the four-digit code.

Table 6-1lists the RS-232 command set.
