8.2. Programming Methods

There is a large selection of commands and interfaces that can be used to program the MagnaLOAD electronic load. A computer can communicate with MagnaLOAD electronic load using either USB, RS485, Ethernet, or GPIB. A programmable logic controller can control MagnaLOAD electronic load operation through analog IO and digital IO pins exposed on the rear connector.

The MagnaLOAD electronic load implements Standard Commands for Programmable Instrumentation (SCPI), a protocol that communicates using simple ASCII commands through a standard serial port. These commands are detailed in SCPI Command Set. Simple digital and analog interfaces to the product are detailed in Operation: External User I/O.
