4. room and oriented towards Frankfurt Main where the time signal transmitter is located The direction is specified on the antenna housing The antenna is connected using BNC socket X7 on the front panel The second signal is the audible IRIG B signal which is transmitted via cable This signal is especially used in USA and Canada but can also be used in other regions when special generators are used In this case high precision clocks can be used as time transmitter however the accuracy can be somewhat less than for the DCF 77 radio signal Socket X6 is provided on the front panel for connecting the IRIG B signal cable The time is indicated on a 7 segment LED displays on the front panel They are mounted horizontally The following is displayed from the top to the bottom Date day of the month and month and time hours minutes and seconds A flashing display indicates that the time might be incorrect e g after switch on The time can also be manually set Two buttons are used on the front panel The cursor is moved with the upper key identified by a flashing display A one is added to the value at the cursor position with the lower key for seconds the value is set to zero Siemens AG Dk Nr 251341 Edition 05 95 3 SIMADYN D Hardware User Manual Notes 1 For the DCF 77 signal the time telegram lasts one minute thus the display can flash for up to two minutes even for perfect receptions until the complete telegram has be
