Installation & Operation Manual GM-TTTPage 282.5 Start Operating ModeFree-running counter operating mode: when this mode is initiated by the start button, the unitsimply switches to a free-running counter mode internally.Pressing this button during start operating mode and having the START function enabled (atsubmenu SET - ... - PARA): the time value which has last been chosen as a start value (menuSET - START) will be transferred to the time addresses of the LTC output, and the generatorkeeps on counting continuously from this start value on.LTC output frequency• 1 st preference: If the unit works within a television system, choose genlock to a black-burstor video signal (select genlock = bb at menu SET - ... - LOCK and press genlock button).• 2 nd preference: With a stable external LTC signal (not a VTR LTC) choose genlock to LTC(select genlock = LTC at menu SET - ... - LOCK and press genlock button).• 3 rd preference: Press intern button to select the internal reference.Internal clock, time/date handling• The internal clock get a pre-set from a built-in or external real time reference. The mode ofoperating with the reference time input is selected at menu REFER - MODE1 and MODE2.Time zone programming is done at submenu ZONE (select the offset and the DaylightSaving Times).• If any time and/or date applications should be kept during the start operating mode, theLTC output frequency should be locked to a stable reference, because this is the frequencyof the internal clock as well. The internal clock can be programmed to get a time and dateupdate every second (menu REFER - MODE 1), in that case the internal clock follows thereference time mostly independent from the LTC output frequency. The binary groups ofthe LTC output may contain time and/or date, as selected at menu SET - ... - USER MOD,for example the date (different formats) or the time and date of the LTC(MTD) format foruse in the MTD system.Time code information: time address• Free-running counter, starts with the values selected at menu SET - START (if enable atmenu SET - ... - PARA).Time code information: binary groups• As selected at menu SET - ... - USER MOD.
