Power monitor

Introduction

PowerTool software and Power Monitor hardware provide * power measurement solutions for mobile devices. PowerTool so ftware and Power Monitor Hardware can analyze the power supply on any device using up to 3-core lithium-ion batteries, providing up to 13.5V and 6 amperes of current. Electrical engineers and software developers can use PowerTool software and Power Monitor hardware to optimize designs and analyze the performance of their mobile devices.

Figure 1: The graphical user interface (GUI) of PowerTool software

The power monitor can measure data on three channels: the main channel, USB channel, and auxiliary channel. The main channel is the channel used by most users for measurement. Provide USB and AUX channels. The following provides detailed GUI information for the main channel, but it is mainly applicable to all sampling sources. Their different situations are indicated in the corresponding sections for USB or AUX measurements.

Hardware and software requirements for developing workstations

It is necessary to use a dedicated Windows platform workstation with a power monitor to achieve optimal performance and results. Slow/older computers may not be able to process samples efficiently enough, and users may see a large number of discarded samples.

ξ Windows Vista, Windows 7, Windows 8, or Windows 10 [XP support stops after 4.0.4.11].

Screen resolution of 1024x768 or higher.

3.2 GHz 32-bit (x86) processor.

ξ 4 GB system memory.

A 40GB hard drive with at least 15GB of available space.

ξ Full speed USB 2.0? Integrated chipset or PCI/PCI Express add-on card.

ξ It is recommended to use USB 3.0 or downstream charging port for front panel connection.

USB hubs (including monitor hubs) should not be used with power monitors for optimal performance.

Install PowerTool software, drivers, and connect to the power monitor hardware

Before installing the latest version, please uninstall any previous versions of the power monitor software from the Control Panel.

Create a new temporary folder (C: \ \) in the root directory of the development workstation.

Copy PowerTool.rip to the development workstation.

Extract the contents of PowerTool 5. X.X.zip to a temporary folder.

Run PowerTool Install.exe and follow the on-screen prompts to install the PowerTool software.

After installing the PowerTool application, this is the first time the workstation will run the PowerTool application. You need to install two drivers, the Power Monitor driver and the firmware driver.

As explained below:

1. Turn on the power monitor in normal mode? The green LED should light up.

2. Under "Device Manager", find "Mobile Device Power Monitor" and there will be a yellow exclamation mark.

3. Right click and select Update Driver Software?

4. Choose to browse the computer to find driver software.

5. Browse to C：\\Program Files （x86）\\Monsoon Solutions Inc\\PowerMonitor\\Drivers\\PC， Then click Next.

After the driver installation is complete, click "Close".

7. Under the Device Manager? Universal Serial Bus devices, please ensure that the mobile device power monitor is properly enumerated.

Firmware driver installation instructions

1. Turn on the power monitor in output enable mode by simultaneously pressing the output enable button and power button? The amber indicator light should be on.

2. Find "Unknown Devices" under "Device Manager", right-click and select "Update Driver Software?

3. Choose to browse the computer to find driver software.

4. Browse to C：\\Program Files （x86）\\Monsoon Solutions Inc\\PowerMonitor\\Drivers\\Firmware， Then click Next.

After the driver installation is complete, click "Close".

6. Under "Device Manager"? Customize USB devices to verify if Microchip's custom USB devices have been properly enumerated.

update firmware

The power monitor comes with the latest firmware and does not require updates in most cases. If for any reason it is necessary to update the firmware, please use the following instructions.

Simultaneously press the output enable button and power button to turn on the power monitor in output/enable mode. The amber indicator light should be on.

Figure 3 Output Enable Button

Launch the PowerTool application and select the 'Refresh' option, which will be enabled whenever a Power Monitor device in boot mode is detected.

Figure 4PM Flash Selection Options

Click the 'Load' button, then browse to the PMFlash folder where the PowerTool application is located, and select the PM_ RevX_ProtXXVerXX_Soot.fwm file. (Please note that X is a placeholder for the correct version information of the given fwm file, such as PM_ RevD_Prot18_Ver21. fwm). The Reflash utility is also compatible with the deprecated. hex file format used in previous firmware versions.

Click the 'Write' button

Wait until the status is displayed? Completed writing?.

After completion, click the X in the upper right corner of the window to exit.

Turn off the power and then turn on the power monitor again so that you now have a green light.

Connect to the power monitor hardware

1. Ensure to carefully read all instructions before operation. Using the power monitor without following the manual may damage the equipment and compromise the protection designed for user safety.

2. Be sure that the power switch in front of the power monitor hardware is not engaged. Hardware should not be powered on.

3. The power switch should be in the outward position, not the inward position.

4. Connect the accompanying 16 VDC/7.5 Amp power supply to the back of the power monitor and a wall mounted power supply (100-240V, 47-63 Hz, maximum 1.6A) that meets the input requirements of the device

For safety reasons, the position of the power supply should be within reach. Ensure this by placing the power module on the same workbench as the power monitor, with the AC input facing the user. Ensure that there are no obstacles in the work area that may hinder you in emergency situations.

On a development workstation compatible with full speed USB 2.0, connect the USB cable to the USB connector on the back of the power monitor hardware, and connect the other end of the USB cable to the development workstation. Do not connect to external USB hub devices.

7. Turn on the power monitor hardware by connecting the front power button. The internal fan will be briefly powered on and then powered off.

Initially, the power light emitting diode (LED) appears amber and then turns green. The green LED is directly connected to the internal power supply of the power monitor.

Connect the power monitor to the device

For information on how to properly configure the device battery to connect to the power monitor, please refer to the appendix.

Always wear safety goggles that comply with ANSI Z87.1 standard when using exposed battery terminals and wiring.

Note that there is always a risk of damaging the device or causing it to overheat, smoke, or catch fire when connecting the power meter hardware to devices with lithium batteries. Although this is unlikely, one must be extra careful. It is recommended to work on fire-resistant surfaces and prepare firefighting equipment when performing battery bypass and connecting the power monitor to the tested device. Immediately disconnect the equipment that has exceeded the safe temperature.

Using PowerTool software

After connecting the device, turn on the power monitor and run the PowerTool software (PowerTool. exe). The software should be connected to a power monitor and display a user interface (UI).

Figure 9: PowerTool software UI connected to the device

Check the software version of the power monitor

The revised versions of hardware (hardware version), firmware (firmware version), and software (software version) should be compatible to achieve consistent and reproducible results and performance.

If the power monitor software has been updated, it is necessary to confirm the compatibility of the firmware. The power monitor will prompt the user that a new firmware is required to run this version of the software. If this situation occurs, it is necessary to update the firmware (firmware version) on the power monitor. Please follow the instructions for updating the power monitor firmware.

The following table describes the various revision numbers displayed in the UI.

To ensure that the correct software is installed, please check the revision field in the UI. Figure 10 below shows the UI area displaying software revisions.
