Introduction

The "GTC link" communication interface is designed to transmit MGETM GalaxyTM 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 MGETM GalaxyTM 6000 nr 6739388XU, for all informations 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.
