RS-232 Connection and
Port Configuration
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).

Serial Command Syntax
• 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/A instead of the four-digit code.
Table 6-1 lists the RS-232 command set.
