Download The Executable

TCD Clock Control is Windows® PC freeware that controls a TCD26, 46 or 86.

This program controls the display, settings and actions of the clock.
It has to run on a Windows PC (2000, XP, Vista, 7 Release Candidate) with a COM port.
This program is free, but for each clock two special adapters and a cable are required
which are not free. They can be purchased from Masterclock.



  • Control a TCD26/46/86 without using its switches.
  • Access all settings--more than those that the switches control.
  • Instantly choose clock, counter or timer display, and control the brightness.
  • Easily switch between date and time displays, and the format for each.
  • Set the time zone, and get the time and date from the clock.
  • Configure counter and timer limits and actions.
  • Get notification from the clock of when a counter or timer limit is hit.
