What is the maximum number of Virtual Devices (Virtual Nodes) that can be connected to a NMEA 2000 backbone?

Explanation:
On a NMEA 2000 backbone, every device or Virtual Device needs a unique one-byte address. The usable address values for devices are drawn from a fixed range, with a couple of addresses reserved for special network functions. After accounting for those reserved addresses, there are 252 addresses left for actual devices on a single backbone. Since each Virtual Device occupies one of those addresses, the maximum number of Virtual Devices that can be connected to one backbone is 252.
