Ports Overview
Flex I/O Ports
Extron flex I/O ports are configurable input or output ports designed to provide
connectivity to various devices such as motion detectors, alarms, lights, LEDs, buttons,
photo (light) sensors, temperature sensors, or relays. All flex I/O ports are tied to a
common ground, but can be individually configured to operate in one of three different
modes:
• Digital Input
• Digital Output
• Analog Input
These ports can be configured by using the default Web pages of the IPL T SFI244 Web
Server (see figure 15; also see
Establishing or changing system or port settings ) or by
dynamically using the Simple Instruction Set ™ commands (see Programmer’s Guide for
the Telnet and Web Browser ) via Telnet, scripts, or Web pages.
