CCT-01 Cable Connection Tester Software

Test, compare, document, and report cable connections.

This guide explains how to connect the CCT-01 tester, compare the current cable against a learned or documented connection, save connection files, generate test reports, and use the tester display.

Before You Start

The software runs in the browser and communicates directly with the CCT-01 through Web Serial.

Browser

Use a Web Serial compatible browser such as Chrome or Microsoft Edge on desktop.

Connection

Connect the physical CCT-01 tester to the computer using USB. Authorize the serial port when the browser asks.

Serial Settings

The app uses fixed settings: 115200 bps, 8 data bits, 1 stop bit, no parity, no hardware flow.

Quick Start

A typical test takes only a few actions once the CCT-01 is authorized.
  1. Open the software.
    Click Open CCT-01 Software or load the software page from your website.
  2. Click Disconnected.
    Plug in the physical CCT-01, click the connection button, then select the CCT-01 serial port when the browser asks.
  3. Let the app read the learned connection.
    When the tester first connects, the software reads the learned connection from the CCT-01 device.
  4. Insert the cable under test.
    Place the cable in the CCT-01 tester and click the Start TEST area in Tester View, or press Spacebar.
  5. Review the result.
    The visual display and report section show pass, fail, wrong connections, and missing connections.
  6. Download the report.
    Click Download Test Report or press F12, enter the cable serial number, then print or save the A4 PDF report.

Display Views

Use the View button or press F1 to move through the available views.

Tester View

Shows the CCT-01 front panel with 64 connector cells arranged as A1 to H8. This is the main operator view.

Map View

Shows a matrix map of every pin-to-pin relationship. Use it when you need to inspect exact row and column connections.

Console View

Shows printable device messages. Keyboard input is available only in Console View.

Visual Result Legend

The software overlays current and reference connection data on top of the tester display.
Learned Connection cell Documented Connection cell ■Current Connection marker Wrong or missing connection Pass indicator
Layer Meaning Learned ■ Current ■ Mismatch

How to read the display

  • If the blue square lands on a learned or documented connection cell, that connection is correct.
  • If the blue square lands where there is no learned or documented connection cell, that connection is wrong.
  • If a learned or documented connection cell has no blue square, that connection is missing.
  • Fail messages use a red square marker to match the red boxes on the tester display.

Main Buttons

The toolbar and tester front panel provide the main operating controls.
Control Purpose
Connected / Disconnected Open or close the Web Serial connection to the CCT-01 tester. Manual Disconnect closes the port and removes the browser authorization, so the next connection asks you to select the port again.
Tester / Map / Console Switch between Tester View, Map View, and Console View.
Current Show or hide the current physical connection layer. Current connections appear as blue square markers and remain displayed when changing between File and Tester reference sources, as long as Current is enabled.
Learned / Documented Show or hide the reference connection layer. The label changes depending on whether the reference comes from the tester or from a CSV file.
Load Connection from File Load a documented connection CSV file. The file becomes the reference connection until you switch back to Tester or manually disconnect the device.
Load Connection from Tester Use the learned connection stored inside the connected CCT-01 tester as the reference connection.
Save Save the learned connection from the tester to a CCT CSV connection file.
Download Test Report Generate an A4 portrait report preview, including date/time, cable serial number, barcode, tester display, terminal names, and result messages.

Connection Files

The reference connection is the expected cable wiring used for comparison.
Learned Connection comes from the CCT-01 tester. Documented Connection comes from a CSV file loaded by the user. When a documented file is loaded, it becomes the reference connection for testing. Changing between File and Tester changes only the reference layer; the Current Connection layer stays visible if it is enabled. The Connection box uses the same color cue as the selected reference: light blue for Tester and light purple for File.

Save Learned Connection

The Save button creates a CCT CSV connection file from the learned connection stored in the tester.

The file starts with CCT-FORMAT-2026-06, includes the date and cable name, then lists terminal definitions and connection rows.

Load Documented Connection

Choose File under Load Connection from to load a documented connection CSV. The app uses the file connection data as the reference layer.

If the file contains connector names and pin numbers, the tooltips and report show the user-defined names below the CCT-01 terminal IDs.

The Connection box shows the loaded cable name and file name using the documented connection color.

CSV File Format

The documented connection file is a simple text CSV file.
Row Type Meaning
CCT-FORMAT-2026-06 Identifies the file as a CCT-01 cable connection record.
Date: Date the file was created, using YYYY-MM-DD format.
Cable Name: User-defined cable name shown in the software and report.
define: Maps a CCT-01 terminal ID to a connector ID and pin number, for example A1, RJ45, 1.
connect: Lists terminals that are electrically connected. Terminals in the same row are treated as connected together.

Test Report

Reports are prepared as a one-page A4 portrait document for printing or saving as PDF.
  1. Run a test.
    Click the Start TEST area on the tester image or press Spacebar.
  2. Check the report area.
    The report appears when both the Current layer and the Learned or Documented layer are displayed.
  3. Click Download Test Report or press F12.
    The software first asks for the Cable Serial Number or report title.
  4. Review the A4 preview.
    The preview includes the tester display, pass/fail status, barcode, terminal names, and wrong or missing connection messages.
  5. Print or save as PDF.
    Use the browser print dialog to print to paper or choose Save as PDF.

Demonstration Mode

Demo mode lets users explore the software without a physical tester.

Pass Demo

Open ?demo=pass to see a passing test with fake connection data.

Fail Demo

Open ?demo=fail to see wrong and missing connections, highlighted cells, tooltips, and report messages.

Demo mode supports the same shortcut keys as the real app. The Sound and Auto Start controls simulate the tester indicator lights only; they do not change the computer system sound setting.

Troubleshooting

Common issues and quick checks.

Cannot Connect

Use Chrome or Edge. Plug in the CCT-01, click Disconnected, then select the CCT-01 serial port. The app no longer auto-connects.

No Device Response

Disconnect and reconnect the CCT-01. Check the USB cable and confirm the device is powered.

No Report Appears

Show both layers: Current plus Learned or Documented. The report is hidden when one of the two comparison layers is turned off.

Port Still Looks Paired

Click Connected to manually disconnect. The app closes the serial port and asks the browser to forget the port authorization before the next connection.
