DIGITAL MATRIX FRAME TO PANEL WIRING
The ICS-2003T differs from the ICS-2003 because it contains an
internal digital audio/data communications module (COM-20) that
works in conjunction with the DIG-2 digital interface module to connect
digital panels to the matrix.
The DIG-2 digital interface module offers two options for wiring the
frame to intercom panels. One option is a single pair of double
shielded (braid and foil) 24 AWG conductor CAT-6 Enhanced STP
cable with RJ-45 connectors.
In addition, each panel may require other connector wiring, depending
on what options and accessories are installed.
Single-Pair Digital
Single-pair digital wiring requires double-shielded 24 AWG conductor
CAT-6E enhanced STP cable with RJ-45 connectors. Pair 1 transmits
and receives multiplexed audio or data between the matrix port and
the panel.
Note: Ensure that the Select switch on the panel’s rear panel is in
the correct position for the intended use.
