3.1 Overview
The E2 range of I/O modules has been designed to provide standard “off-the-shelf”
telemetry functions, for 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 go through an internal diagnostics
check where it will perform some internal setup and diagnostics checks to determine if
the module is operating correctly. These checks will take approximately 90 seconds.
The table below indicates the correct LED indications.
