Notes

The interface converter VAZ-R4-R2 is the ideal interface converter between the RS 232C inter-

face of the PC and the RS 485 interface of the AS-Interface Gateway.

The converter requires no additional external power supply. For this reason, it is highly suitable

for mobile use on a laptop computer or notebook.

The RS 232C/RS 485 converter is simply plugged between the AS-Interface Gateway and the

RS 232 connection cable. Only one device with an RS 485 interface can be connected up to

the interface converter.

The RS 232C/RS 485 converter can be used on various operating systems. By means of the

AS-i Control Tools for Windows an AS-Interface Master with an RS 485 interface can be opera-

ted as well as an AS-Interface Master with an RS 232 interface. The RS 232C/RS 485 conver-

ter supports all transmission rates up to 57600 Bit/s.
