Cable Tester Report using Spreadsheet

This page is specifically written for customers who do not want to hold onto a Master Cable sample to do testing of their cables using the product CCT-01 Cable Connection Tester. A spreadsheet can be used to record the master cable connection for future testing use.

Using a master cable for CCT-01 cable tester is still strongly recommended. For more information about the background of using spreadsheet as a means of generating cable test report (without the need for master cable), you can click here for more information.

Benefits of using Spreadsheet

While the design of CCT-01 Cable Connection Tester is not intended for use with spreadsheet, there are a few benefits that worth mentioning.

  • Documentation for your master cables connection.
  • Easier to generate reports that is printable.
  • Allows customisation of your own cable test report format.

We will not be touching on the customisation of the report. This is mainly programming using spreadsheet formulas. For those who are confident in the programming, you can download our spreadsheet and begin your customisation from our sample sheet.

For our cable tester report spreadsheet, we are using Google Sheet. The following section we will explain how to use the Google Sheet that we have written for use with CCT-01 Cable Connection Tester.

Access to Google Sheet here

Google Sheet test report is available for access. Please grab a copy from our Google drive. Save a fresh copy for your own use.

Do feedback to us if you encounter any issue using it. We will continue to make improvement to the sheet.

Sheet: Test Report

Quick introduction to this Google Sheet

This is the Cable Tester report spreadsheet. There is a total of 12 sheets on this file.

Sheet 1 Test Report

On this page, there is two parameters to input. White background cell are places where you can key in data.

On the cell F1 is for you to key in the MasterCable sheet’s name that you want to compare with. (remember to complete the MasterCable sheet before you can use this cell)

On the cell F3 is the test result of the cable connection that you have tested from the CCT-01 Cable Connection Tester. The later section below, we will provide you with the instruction to copy and paste the cable tester result onto this box cell.

Sheet: MasterCable

Sheet 2 MasterCable Template

This sheet is a template to create as many MasterCable Sheets as you required. It is locked to prevent you from making changes accidentally.

Sheet 3 onwards are copies created from MasterCable Template

There 10 sheets of MasterCable for you to create a connection map for your cable. You can create more sheets if needed, and you can rename the sheet to any names that suits your work flow.

Cable Testing setup example

This setup is using a serial communication cable as an example. It has connector 01 Dsub 9 pin (female) on one end and connector 02 Dsub 9 pin (male) on the other end. The correct connection is pin to pin connection.

We will use this test connection for the setup of the Cable Tester report on the Google Sheet.

A total of 4 plugs is used. Connector 01 is plugged to A B, while connector 02 is plugged to C D.

Serial Terminal Software Preparation

In the following step-by-step example, we are using Docklight serial terminal software (paid version) to print out the test report.

The free version of Docklight does not allow copying of the report. For an alternative serial terminal software, you can use MobaXterm or Anticyclone Systems (online cloud version) as the alternative serial terminal software to print out the test report instead.

Read out cable connection result

The cable tester will scan the cable and generate us the connection result which we can cut and paste, to use it on the Google sheet report.

Connects up the CCT-01 cable tester via USB cable to your computer.

Launch the serial communication software, and connect it to the cable tester.

For more information about connecting this cable tester tool to Docklight, you can refer to this page for more information.

Click ESC to launch the menu. Key in ‘2’ to command the cable tester to scan the cable for the cable connection.

CCT-01 Cable Connection Tester command menu.

After a quick scan on the cable, the cable tester will generate the report showing the connection matrix.

Connection matrix generated after sending the read command ‘2’

Select and copy the generated connection matrix. This connection matrix will be later paste onto the Google sheet. The spreadsheet will analyse this set of data and generate you the report from the Google sheet instead.

Ensure that you have copied the entire row from row A1 to row H8.

Selecting the generated connection matrix result.

Document your master cable

First thing first is to do a simple documentation of your cable on the Google sheet.

Go to the 3rd sheet labelled as “MasterCable01“.

You will get to see 3 blank regions (white background) on the column ‘F’. These are field that requires your input.

The red colored cell are the matrix map for the cable connection. Since the connection matrix is not inserted, it is showing a light red background which indicates an error in the input.

Sheet: MasterCable

Data entry to the MasterCable01 sheet.

  • F1 cell – Put a name or comment for this sheet.
  • F3 cell – Paste the connection matrix that you have read from the working master cable that you have. In our example, this will be the RS232 cable that we have scanned and read.
    When the correct connection matrix is paste, the matrix cells will change from red to something that look like the example here.
  • Cell F7 onwards – are rows of cells for you to add in your own comments to label each wire connection on the CCT-01 Cable Tester.

You have completed the documentation for your first master cable. We have named this sheet as “MasterCable01“.

You can continue to document your other cable connection on another GoogleSheet.

Example of filling in the blanks documenting your cable.

Using the Test Report on Google sheet

This assume that you have successful completed the documentation of your master cable connection sheet.

On this test report sheet, there are two input field.

  • F1 cell – Key in the name of the sheet of the documented cable connection that you want to compare with. In this example, we choose the sheet “MasterCable01“.
  • F3 cell – paste in the connection matrix of a new cable that you have tested.
Sheet: Test Report

If only F1 cell is selected, the matrix will display the documented connection of this master cable.

Display connection matrix of the master cable when the sheet name of the MasterCable01 is keyed onto the cell F1

If only F3 cell is entered, the matrix will display the tested cable connection.

In this example, we use a cable connection with error in it.

Display of the connection matrix of the test result when only the connection matrix is keyed into the cell F3.

When both F1 and F3 are entered into this sheet, you will be able to see the generated result after comparing these two sets of connection. There will be an indicate display on cell F2 showing either “Same” or “Different”.

When the red “Different” indicator appeared, it means that the test cable is different from the master cable connection. This means a failed tested cable.

Result is Different after comparing the connection matrix on F1 and F3.

When the green “Same” indicator appeared, it means that the test cable is the same as the master cable connection. This test is a Pass.

On the connection matrix indicate symbol to represent the connection status between 2 terminal pins on the cable tester.


  • @ (blue) – a connection.
  • – (light gray) – no connection.
  • . (gray) – indicates the same terminal pin (not tested).
  • M (orange) – a missing connection.
  • X (red) – unintended connection detected.
Result is Same after comparing the connection matrix on F1 and F3.
