Description

The GT6064 is an ISA scanner / multiplexer that plugs directly into an ISA or GTXI PC mainframe. The GT6064 provides either differential or single-ended scanning capability and is configurable via software commands or DIP switches.

Features

The GT6064 is available in two versions: commercial and high reliability (Hi-REL). The commercial version includes plastic molded DIP reed relays and is suitable for most commercial applications. The Hi-REL version uses quasi-military relays and is suitable for industrial and military applications.

Architecture

The architecture of both versions consists of four scan groups, A through D, which provide scanning/multiplexing of eight differential or 16 single-ended channels. Mixed configurations of single-ended and differential channels can be used simultaneously. Typical configurations include:
  • 1 x 64 Single-ended
  • 1 x 32 Differential
  • 2 x 1 x 32 Single-ended
  • 2 x 1 x 16 Differential
The GT6064 can operate in three modes: direct switching, universal bus switching, or combination switching mode. In the direct mode, the GT6064 can route each scan group directly to a dedicated bus without routing through additional relays. This mode is differential only.
The GT6064 includes four universal buses, X0, Y0, X1 and Y1, which are accessible by each of the eight scanning groups in universal switching bus mode. Each scan group can be utilized in either differential or single-ended mode, extending its scanning and multiplexing capability to sixteen channels per group. Since the eight scanning groups are independent, they can be used for either scanning to a direct bus or the universal bus.
In combination switching mode, each scan group may be individually configured for use with direct or universal busses, thus allowing multiple configurations.

Direct Mode

In direct mode the GT6064 can route each of the scan groups directly to a dedicated bus without routing through additional relays. This mode is differential only.

Universal Bus

In addition to the direct buses, the GT6064 includes two universal buses, Bus X and Bus Y, accessible by each of the four scanning groups. In this mode, each scan group can be utilized in either differential or single-ended mode, extending its scanning and multiplexing capabilities to 16 channels per group. Since the four scanning groups are independent of one another, they can beused for either scanning to a direct bus, or the universal bus.

Combination Mode

Each scan group may be individually configured as direct or universal bus, thus allowing for multiple configurations.

Programming

The GT6064 is supplied with software drivers to support development environments such as ATEasy, C++, C, Microsoft Visual Basic, Pascal, Delphi, and more. A virtual panel is provided for standalone applications and debug
