Protocol

DIY Ant8 probe cable

The Ant8 cable shipped with the device doesn't have the best quality probes/hooks, but you can easily make your own cable where you can attach the better-quality E-Z Hooks.

Requirements:

  • 10-pin colored ribbon cable, such as this one.
    • The colors match the one shipped with the Ant8 (white, gray, purple, blue, green, yellow, orange, red, brown) if you remove the 10th (black) lead. The brown lead is GND.
  • A "SUB-D" connector where you can attach the ribbon cable, such as this one.
  • 5 female-female jumper wires, such as these ones, which we'll cut into two halves to get 10 female connectors (only 9 needed).
  • 9 short pieces of heat-shrink tubing.
  • 9 E-Z Hook grippers/hooks to attach to the cable.

Photos:

  • Sub-D connector

  • Ribbon cable (black lead removed)

  • Connected cable

  • Jumper wires

  • Cut jumper wires

  • Heat-shrink tubing

  • Prepared heat-shrink tubing

  • Soldered jumper-wires

  • Heated up

  • Finished cable with E-Z Hooks
