6.1 
RS-232 Connection 
and Port Configuration
To interface the Crystal Series LCD Display 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 Crystal Series LCD Display 
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 Crystal Series LCD Display 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 Crystal Series 
LCD Display ignores it and returns -N/A instead of the four-digit code.
