Figure 3 - Microflex – Internal description
All connections to the Microflex including power, video, data and audio cabling are
made via pluggable industrial terminals. The signal description for each terminal is
indicated on a cabling label inside the enclosure.
____________________________________________________________________________
Care must be taken not to mix a Microflex FXS interface and FXO interface when
connecting the audio signals. Connecting a telephone line (FXO) instead of telephone
set can damage the FXS sub-module. A label at the back of the enclosure indicates the
audio option selected (O for FXO, S for FXS and L for line level).

The industrial terminals are mounted on an interconnection board. This removable
board integrates a two stage surge/lightning protection circuit providing industrial
type protection for the main electronics.
____________________________________________________________________________
Each surge or lightning strike weakens the protection circuitry. It is recommended in
lightning prone geographical areas and as part of a maintenance program, to replace the
protection board every 2 years. Please contact ComLink factory for part number and
ordering procedure.
