Overview
The gpio.NET Core interface is extended by analogue inputs each providing
selectable shunts for current measurement. The modules easily integrate into
existing Modbus systems and can be identified and configured by a unique serial
number even in a running system. Beyond that, they offer a uniform set of
registers over the hole gpio.NET family.

Interfaces
For communication, gpio.NET modules feature up to two Modbus interfaces. R-
Series provide routing between those. The DSUB connectors (X10 and X11) are
only available in R-Series.
USB
The USB device port (X1) belongs to the standard equipment of gpio.NET cards.
Because of this, the module is accessible from prevalent PC or laptops. To deal
with issues resulting of this, Modbus ASCII is the only available protocol used
