Modular I/O Configuration Guide56
Remote Configuration using a Web Browser
Modular I/O frames are remote controlled and configured through a network connection between the FC972 and a PC running
a common web browser. This Ethernet-based external access is maintained by a dedicated 32-bit communication processor in the
FC972 that runs an HTTP server, a UDP server, and an SNMP agent.
After launching the browser on the PC and entering the frame’s IP address, all data including GUI is served out from the FC972
to the browser window. Device-specific configuration software is not required on the PC.
The FC972 communication processor does not directly control the module parameters. Instead, it transfers commands and data
between the individual module’s processors which control their parameters and GPIOs. The FC972 communication processor
and individual module processors both communicate internally over the CAN bus. This two-stage approach insulates external
communication from audio processing so the Frame Controller’s firmware can be updated without disrupting audio. The func-
tions available from the GUI interface may vary with different versions of the Frame Controller’s firmware.
