Controlling Pearl-2 using RS-232 / serial port
Pearl-2 has an RS-232 / serial port control interface for integration with existing control room and board room
equipment.
Important considerations
l Each command sent to Pearl-2 over RS-232 must be terminated with a line feed(LF) character
(ASCIIcode 10). Make sure that your software adds the line feed to each command.
l For values with spaces, enclose the value in quotation marks. For empty values, use empty quotation
marks with nothing between.
l You must always follow a "SET" command in RS-232 with the "SAVECFG" command. Otherwise the new
configuration setting(s) will not take effect. See the "SET" examples that follow.
For a complete list of supported SET and GET parameters, see Configurationkeys forthirdparty APIs . To
connect the RS-232 cable and configure RS-232 on Pearl-2, see Connect and configure the RS-232 port
