3.17 T31 Network Adapter
The T31 network adapter is a small circuit board that is installed inside the
MX800 transceiver to enhance serial communications to the MX800. This is
achieved because the board implements a protocol especially designed for
efficient multi-drop serial communications.
MX800 transceiver to enhance serial communications to the MX800. This is
achieved because the board implements a protocol especially designed for
efficient multi-drop serial communications.
The T31 board intercepts the serial data port of the MX800 encoding and
decoding the external data stream, converting it to/from standard MX800 data
required by the MX800 Micro-controller board. It also intercepts the
MX800’s DB25 Digital I/O connector and provides additional digital inputs
to allow more than the standard 16 network addresses to be set externally.
The additional pins required to support the additional network address inputs
are available externally on a DB44 high density connector that replaces the
standard DB25 female connector (CN3) of the MX800. CN2 is also located
on the board and it’s connection to the MX800 Micro-controller board
provides the power supply for the T31 option board.

Standard MX800 data when using Mxtools software will pass seamlessly
through the T31 board without any conversion.

3.17.1 Optional Dongles
There are two different dongles available that can be plugged directly into
CN3 (T31’s DB44) to allow external selection of the MX800’s operating
channel and it’s T31 network address. The dongles can be set and be used as
a method to ensure that a pre-programmed radio is set to the right channel
and network address at a particular location, allowing a plug-and-go
operation for non technical personnel to carry out equipment changeovers.
