How many RS232 devices can be controlled per Data Hub / AVA software instance?

The Data Hub is available with 2 or 4 RS232 ports.

Up to 4 Data Hubs can be configured per AVA software instance.

Therefore, you can have up to 16 RS232 devices (4 x 4) per instance of AVA.

This is the maximum recommended number of devices for AVA; this is what we have tested up to.
