Which devices (equipment/apparatus) can I use with AVA? AVA Software is compatible with a wide range of devices with RS232 ports. To review our current list of compatible devices, in the AVA help pages, accessed via AVA Software (which is free to download to use in demonstration mode here), search for ‘Device Driver Information’ and select the first result. If you would like to use AVA with an RS232 device not on the list, we may be able to create a driver for it (part number RR20217: Driver Configuration Service). Please send us full details of the device, including an instruction manual, to review. If the device does not have an RS232 port (interface), it cannot be used with AVA.
