Serial Communications; Rs-232 Connection And Port Configuration; Serial Command Syntax - Runco CL-420 Owner's Operating Manual

To interface the CL-410/CL-420 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 9600, to match that of the CL-410/CL-420
RS-232 port.
Table 6-1 lists the RS-232 command set. All commands are in ASCII format and must be
in UPPERCASE.
When you send a valid command, the CL-410/CL-420 executes it and acknowledges it
with the first three characters of the command followed by "OK;" for example, "RRAOK."
When you send an invalid command, the CL-410/CL-420 ignores it and returns the first
three characters of the command followed by "NG;" for example, "RRXNG."

are complete, you can use these commands to store the settings in the selected memory.
2. The power on command (PON) will not provide an OK reply; it will instead reply with a random
character. For your automation system, simply ensure that you receive a character after the
PON command. If you do not get any reply after PON, send PON again.
