Chapter 3 - Operation
3.1 Overview
The WI-I/O 9-U2 range of I/O modules has been designed to provide standard “off-the-
shelf” telemetry functions, at an economic price. Telemetry is the transmission of data or
signals over a long distance via radio or twisted-pair wire cable.
3.2 Indications
When power is initially connected to the module it will perform some internal setup and
diagnostics checks to determine if the module is operating correctly. These checks will
take approximately 80 seconds. The table below shows the correct LED indications.

message, any subsequent retry messages will not be indicated.
