ASRL and GPIO Interface Overview

As shown in the following figure, a typical ASRL (RS-232) interface consists

of a Windows PC with one or more RS-232 COM Ports. Each COM port can

be connected to one, and only one, Serial instrument via an RS-232 cable.

A typical GPIO interface consists of a Windows PC with an E2075A GPIO

card that is connected to a GPIO instrument via a GPIO cable.
