AISG Free Download

The University of Sheffield AISG Freeware provides a cut down version of the device emulator available in the Test Tool. It is designed to help test whether a Primary station follows the communication protocol specified by AISG1. A log of the HDLC frame exchange is provided on screen and in the form of a text log, which is stored on the hard disk. The device emulator can hold the description data of only one device at a time, and the represented device cannot be deleted. It is possible to overwrite a device, but devices may not have the same Unique ID.
