XT-9100 Extension Module/
XP-910x Expansion Modules
The XT-9100 Extension Module and its expansion modules have been
designed to provide additional input and output capacity within Metasys

Networks and specifically for the DX-9100 Extended Digital Controller.
The XT-9100 module provides the communication interface and the
XP modules provide the analog and digital inputs and outputs.
A Supervisory System communicates with an XT-9100 via the N2 Bus or
Bus 91*. Each XT-9100, depending on its expansion module combination,
can have up to 16 inputs/outputs, eight of which may be analog.
The DX-9100 communicates with the XT-9100 via the XT-Bus, and when
the DX-9100 is connected to an N2 Bus (or Bus 91), data from the
XT-9100 is available to a Supervisory System. Up to eight XT-9100
modules can be connected to the XT-Bus. Each XT-9100 provides,
depending on the type of the connected XP expansion modules, either
eight analog points or eight digital points, extending the input/output of a
DX-9100 by up to 64 remote input/outputs. Modules with 16
input/outputs may also be connected, provided that the total number of
remote input/output points on the DX-9100 does not exceed 64.
Configuration of the XT-9100 is achieved by using a personal computer
with GX-9100 Graphic Configuration Software (GX Tool) supplied by
Johnson Controls. When the serial interface of the XT-9100 is connected
directly to the N2 Bus (Bus 91), the GX-9100 will download and upload
configurations over the N2 Bus (Bus 91). When the serial interface of the
XT-9100 is connected to the XT Bus, the GX-9100 will download and
upload configurations via the N2 Bus (Bus 91) connected to the DX-9100
to which the XT-Bus is connected. The DX-9100 retransmits
configuration data to the XT-9100 on its XT-Bus.
