The display is a 6860 model. On startup, there are built in diagnostic patterns, one of which is a count up timer. DIP switch 1 controls whether the display enters diagnostic mode or not. Once in diagnostic mode, the other DIP switches determine the diagnostic pattern to loop on.
Flip DIP switch 1 to the ON position and cycle power to exit diagnostic count up clock mode.
The 6860 does not contain a time-of-day standalone mode since the display does not know what time zone or time of day is current. The 6860 was designed to interface as a display of race results for several RaceAmerica timers or PC software. Download our free Display Utility software from our website (www.raceamerica.com) under SUPPORT then under DOWNLOADS click on UTILITY SOFTWARE and scroll down to Display Utility. There is a time-of-day function in the Display Utility program that will send the current time of day to the display, then disconnect the PC. If the display looses power, you will need to reconnect the Display Utility to set the time of day in the display. We actually utilize a time of day display in our manufacturing area setup this same way.
To connect the display to the PC, there are a number of cables on our Online Store (store.raceamerica.com) depending on if the PC has a 9-pin connector or USB port. In our Online Store, click on DATA COMMUNICATIONS, then RS232 SERIAL. 45232A is a USB to display cable or 6033A is a 9-pin to display cable. If the PC does not have a 9-pin port, your will need to purchase a USB-to-Serial adapter from a local computer store to use the 6033A cable.
If you wish to build the 6033A cable, go to our website to SUPPORT then under TECHNICAL SUPPORT click on APPLICATION NOTES. Select application notes AN-CBL002 and AN-CBL004.
Good luck whichever way you go. I think the end result will be what you are looking for.
