Touch Panel Interface on September 12, 2015 | Marketing Team Limitimer can be controlled by popular touch panel systems. Use the Cat-5—DB-9 adapter (TP-2000X) to pass ASCII control codes between Limitimer and the touch panel centeral controller. The touch panels can access all timer functions including setting the time and starting and stopping the clock. Real-time Time Remaining, phase lights and other data from the timer may be displayed on the touch panels. In addition, when using our large digital displays (ASL4-ND3), the touch panel can change the display from a count-down clock to a 12-hour time clock and vice versa.
