Introduction
The "GTC link" communication
interface is designed to transmit
MGE
TM
Galaxy
TM
6000 UPS
operating information and remote
"on/off" commands (if available) to
an external computer.
The JBUS hexadecimal
communication protocol is used
(the JBUS ASCII mode is not used
in this application).
The "GTC link" features two
symmetrical communication
channels, both with a simplified
V24 (RXD and TXD only) and an
RS485 interface.
It consists of a "GTCZ"
communication board (central unit)
and a "RAUZ 1" (communication
network management and
interconnection board).
In option, two additional
communication ports can be added:
"GT2Z" board (central unit) and
"RAUZ 2" board (communication
network management and
interconnection board).
Refer to the "communication
options connection manual" of
MGE

about connections.
"GTCZ" and "GT2Z"
boards features
The "GTCZ" and "GT2Z" boards
are functionally divided into two
main modules:
The ACQ module
◗ performs data acquisition;
◗ monitors the status bus of the
monitor/control boards;
◗ computes physical quantities and
battery backup time;
◗ processes alarms;
◗ sends commands to monitor/
control boards;
◗ stores configurable parameters
and communicates with the "Soft
Tunor" software, used by APC by
Schneider Electric after-sales
service;
◗ transfers data using the on-board
communication channels.
The COM module
The COM communication module
is designed for external devices
(e.g. "AMUZ" type board of a
"Monitor" or "Tele-Monitor") to:
◗ retrieve information and
parameters processed by the ACQ;
◗ send commands to monitor/
control boards;
◗ be integrated into other systems
(remote indications and
supervision).
Each "GTCZ" or "GT2Z" board is
equipped with two symmetrical
communication ports, COM1 and
COM2:
◗ on the "GTCZ" board:
◗ ◗ COM1 for a "display devices"
network consisting of "AMUZ"
boards in a unitary or parallel
connected UPS configurations,
◗ ◗ COM2 for a supervisory system;
◗ on the "GT2Z" board:
◗ ◗ COM1 and COM2 for a
supervisory system.
The "GTCZ" and "GT2Z" boards
are configured with the APC by
Schneider Electric after-sales
customization software called "Soft
Tunor".
The computer link is via the test
connector located on the front
panel of the cubicles and performs:
◗ configuration, calibration and
control of the ACQ module;
◗ configuration of COM1 and
COM2 ports.
