17.11.1.4 Serial ports
The SPC controller provides 2 serial ports (RS232) that offer the following functionality:
l
X10:
Serial port 1 is a dedicated interface that supports the X10 protocol. This protocol allows for
use of the existing power cables of a building to transport control information to X10 devices
providing the ability to trigger and monitor these devices via the SPC Controller programming
interface.
l
Logging of Events:
The Serial port 2 interface provides the ability to connect to a serial port on a
PC or a printer. With this connection, a terminal program can be configured to receive a log of
System Events or Access Events from the SPC controller.
l
System Information:
Serial port 2 also provides an interface via a terminal program that allows for
the execution of a set of commands to interrogate the controller for specific system information.
This facility is available only as a tool for debug and information purposes and should only be used
by experienced installers.
