Accurate time will be read by allserially connected displays. Time may be offset by one or more hours- use IR remote control progam option 4 consult manual page 10 formore information.Use a straight thru RJ-45 patch cable (from either RJ-45 connector) ifthis clock is being fed with remote master time sync and if downstreamdisplays are not required to display remote timer information.Repeat up to 35 displays.Note: final display serial line must be terminated with a150Ω resisitor (use terminator DIP switch on large clock.)Use a crossover RJ-45 patch cable to slave Time-of-Dayand/or timer displays to downstream units.Via the IR remote control enter the program mode and select option 3 for serialtime-of-day format. Select “rs1” for time-of-day only re-display from the masterclock. Select “rs2” for time-of-day and timer re-display from the master clock.You must use a crossover RJ-45 patch cable if this display is themaster (first clock) in the serial chain or, if you want downstreamclockcs to display remote timer as well as Time-of-DayPC Clock Input SyncNote: Software/hardwarekit available (Radio Systemspart # CT-SYNC) to updateWindows PC clocks via USBfrom the CT-2002serial data streamRadio Systems, Inc.
