Chapter 4 — Remote Operation

4-1 Introduction

Once connected to a PC using a USB cable, the MA24106A shows up as an RS-232 Serial COM port on the PC. You can check the COM port number from the Tools drop-down menu or by using the Windows control panel. The COM port number and following settings are needed in order to control the sensor remotely:

•Baud Rate: 115200

•Data Bits: 8

•Parity: None

•Stop Bits: 1

When the power sensor is connected to a PC using a USB cable, it will be configured in idle mode. While in idle mode, the sensor is waiting for a START command from the host application. The application developer must send the START command to put the sensor in measurement mode. Once the sensor is in measurement mode, various commands can be sent to communicate with the power sensor. When the application is being closed, the STOP command should be sent to put sensor in idle mode.

Note: In Low Aperture Time mode, the sensor takes about 70 milliseconds to respond to all commands with the exception of the ZERO command, which takes about 19 seconds.

In High Aperture Time mode, the sensor takes about 700 milliseconds to respond to all commands with the exception of the ZERO command, which takes about 19 seconds.

4-2 Remote Operation Commands Summary

The following is a list of commands available to control the MA24106A:
