Overview 1/1Overview

The SRM Ethernet Torque Analysis software is designed to display pedaling torque inputs in real time and provide the user with the ability to record and analyze data.

Torque data is useful when working to determine optimum bike fit, the result of changes made to position, athlete pedaling dynamics, and when working to rehabilitate after injury.

Data collected can be saved, reloaded, and exported for use in various other applications and formats.

System setup 1/1

System setup

Hardware setup

1. Ensure current set-up of PowerMeter, including positioning of the sensor cable

2. Connect SRM Ethernet Torque Analysis Box to the sensor cable

When using 4-pin sensor cable from Powercontrol 4 Torque output, use the digital input port of the SRM Ethernet Torque boxWhen using 5-pin sensor cable, use the analog input port of the SRM Ethernet Torque box

3. Connect AC Power supply to the power input port of the SRM Ethernet Torque Analysis Box, check if power led (green color) is on (see troubleshooting for any problems)

4. Secure SRM Ethernet Torque box in stable position5. Start pedaling and check if the cadence led (amber color) is flashing

when the cadence magnet inside the PowerMeter passes the sensor (see troubleshooting for any problems)

6. Connect the network cable to the LAN port on the SRM Ethernet Torque Analysis Box and to your computer

Software setup

1. Configure the network address on your computer to the same subnetwork of SRM Ethernet Torque Analysis Box (see here for detail)

2. Download the software from SRM website3. Ensure you have Java installed on your computer otherwise download

from Java website4. Launch the SRM Torque Software5. When the software first runs, it will ask you to define a writable folder to

save the data. Select a folder.6. Main screen is now shown; go to Settings by clicking on the lower right

corner button or through the Options-Settings on the top menu and configure the program

7. Start pedaling, and check the connection indicator on the lower left corner of the screen: this indicator should be green, if not go to Log and check the messages

Main view

The majority of this view is used by a graph showing online data: the x-axis of this graph is measuring the Angle of revolution in degrees, and the y-axis is the Torque in Newton-metersThe left side of this view shows numerically the last revolution value for Power, Torque, and Cadence

The right side of this view has two buttons: Record and Reset; pressing the Record button begins recording revolutions, pressing the Reset button clears all stored data.The right side of this view also has an area to define the Automatic Stop preferences. Selecting

Selecting None will result in recording revolutions until stopped manually with the Stop button, selecting Revolutions will result in recording the specified number of revolutions entered and selecting Time will result in recording the specified seconds of time entered

The Notes area is for entering information specific to the revolution data that you record; any notes entered here will be displayed in the revolution table in the Analysis viewDirectly below the main graph, there is a field showing numerically the index of the revolution with the relative cadence and power

The bottom of the main view has a tracking feature which allows you to see specific angle and torque data as you mouse over the graph

Analysis view

The top part of this view contains a revolution table, showing data from all recorded revolutionsWhen you select a revolution, the relative profile is shown in the Analysis graph

Selecting multiple revolutions results in the graphical display of all revolutions (For windows operating system, this is done by pressing Ctrl-Click. When using Mac OS, this is done by pressing Commnand-Click)

The right side of this view has a "Data Operation" area; to export data, first select the output format (CSV, PNG, or PDF), then, pressing the "Export" button will export all selected revolutionsTo calculate the average graph of revolutions just select 2 or more revolutions and press the "Calculate Average" button

Views 4/6

The "Save" button allows you to save all checked revolutions (see "Save" column in revolution table); the number shown on the "Save" button indicates the number of flagged revolutions. All files will be saved in the data folder defined in the "Settings-System" window. The naming format of the SRM Torque Analysis file (.sta) is: initials-YYYY.MM.DD HH.mm.SS where initials can be changed and the system automatically uses the user default data

The "Load" button allows you to open revolutions previously saved; press the "Load" button, select a file, then press "Load File" button (uncheck "Update Statistics" if you do not want the file to affect current statistics)

Pressing "Select File" allows you to Load another file; when all files are loaded, press "Close" to exit the window

Views 5/6

The "Marker Info" area is used for reading measurements from the graph. First, select one or more revolutions, then click a starting point, followed by an ending point. The delta of these two points will be displayed in the "Marker Info" area, showing both "Angle" in degrees and "Torque" in Nm. The "Marker Color" button allows you to change the color of the lines used to display the marker. The "Delete Markers" button clears all markers

The menu in the lower right corner allows you to display the data in different torque values

Settings 1/5

SettingsThe Settings window has 5 tabs:

1. The Graph tab allows you to adjust the number of simultaneous revolutions shown on the main graph, as well as select custom colors for each revolution by clicking on the color. The Add and Delete new revolution buttons allow you to vary the number of revolutions between 1 and 10. Checking the "Automatic Torque Scale" box will result in a self-adjusting y-axis for torque values. By leaving this box unchecked, you can manually select the maximum torque value shown on the y-axis of the main graph.

The User tab contains relavent information for all user profiles. The User profile drop-down box contains a list of all stored users and their Parameters are shown when selected.

Settings 2/5

To change any parameters to a user, input the new value and click Apply modification button. To Delete a user, select user from drop-down box and press Delete user button. To create a new user, input a user name for the profile, and all the parameter information, then click "Add new user" button; the current user profile is shown in red. To change this, select a different user from the "User profile" drop-down box, and click "Use current user" button; the current user information will be updated. The parameters from the current user provide important information for the accuracy of the data being collected for each revolution, such as the weight and crank length. The status bar on the bottom of the window will provide notification for all actions done.

Troubleshooting 2/2

PowerMeter battery issues

The PowerMeter battery is not self-replaceable. You will need to send it to the Service Center for replacement. ATTEMPTING TO REPAIR IT YOURSELF WILL INVALIDATE THE WARRANTY, and could cause permanent damage to your PowerMeter. Battery life of the PowerMeter will vary between PowerMeters. General expectancy of wired systems:

DuraAce/FSA/track approximately 1500 hours of usePro and Amateur approximately 1000 hours of useCannondale/Specialized approximately 750 hours of use

General expectancy of wireless systems with ANT technology:

DuraAce/FSA/Pro approximately 1400 hours of useCannondale/Specialized approximately 700 hours of use

If the variance of your zero-offset begins to fluctuate more than normal and your hours of usage is in-line with the above, your battery likely needs to be replaced. Please download the Service Form and send your PowerMeter back to the Service Center for replacement.

Activation point 1/1

Activation point

Changing the activation point for the revolution is necessary when you wish to view the revolution with a specific starting point.Your powermeter triggers cadence at the point where the reed switch inside the powermeter passes the sensor.To change the activation starting point for the torque revolution, you must first measure the angle in degrees of your sensor cable (see picture below).

This means the revolution starts at 42 degrees from the vertical position

If you want to have the revolutions started from 90 degrees just set the activation point to 48 (90-42=48).

Network configuration 1/2

Network configuration
