Chapter 5: Services Described 37
GENERAL PURPOSE IO (GPIO) SERVICE
Overview
The General Purpose IO (GPIO) service can be thought of as a “Miscellaneous Function” or a catch-all type
Service. Services that don’t neatly fit into any of the other services described may often be found under this
umbrella service type. Some of the common I/O types associated with GPIO services are IR, RS232 serial, and
relay contact closures.
Many GPIO services have LUA interpreters associated with them. This allows custom drivers to be written to
perform any functionality desired. See Appendix for commands to control specific devices.
ROOT SERVICE
Overview
Every device has exactly one root service. The root services manage common and miscellaneous housekeeping
functions for each device. The root service is always active, even when all of the other services on the device
have been disabled.
