TymMachine 7000 Microchip Programmable Time System

The Microchip / Datum TymMachine 7000 Programmable Time System is both a time code generator and a time code translator that can easily be switched to function as a synchronized time code generator. An integral serial RS-232 port allows control of many of the variables via the utility program. Optional capabilities, such as Video Time Insertion, Parallel Time Output, and Tape Search and Control are provided by means of plug-in modules that are easily installed in option slots in the rear of the chassis.

The Time Code Generator outputs IRIG B120 (with Control Functions and Straight Binary Seconds) via a BNC connector, and also outputs a selected code (either IRIG A132, B122, G142, NASA 36, 2137, XR3 or ANG &Q53 (250 Hz) [BCD TIME ONLY] via another BNC connector. The generator can be set to operate independently, even while the translator is processing a time code input. The Time Code Translator reads any of 14 different time codes at various speeds (tape speed-up and slow-down) and both forward and reverse directions. The time code input is conditioned by both a lowpass filter and a phase-locked tracking filter to provide the ultimate in performance when translating time codes that are contaminated by noise and distortion.

Most operating parameters are stored in non-volatile memory, making initialization after a power loss unnecessary. A rechargeable battery prevents time loss after an external power failure. The unit runs automatic self-test diagnostics each time power is turned on. Any abnormal test result is displayed on the front panel to aid in determining the proper corrective action.
