CT-2002 Manual Page 6 Slaved Displays To Utilize as a Slaved Clock Display (CT-2002 Display units only): 1. Consult page 10 for setup functions to select either RS or SMPTE sync format. 2. Provide serial data to the unit. Choices of serial data are SMPTE time code and Radio Systems Time-of-Day data from CT-2002 GPS or CT-2002 Master units. In addition a CT-2002 display unit can be used to provide Time-of-Day and Timer data in the Radio Systems format. To connect to slave Time-of- Day displays only, wire only the serial data input terminals in parallel (use either the terminal strip or RJ-45 connectors—see the connections diagram on page 22). 3. The “SYNC” front panel LED will light and the time-of-day will immediately synchronize to the master unit readout. 4. Time-of-Day setting is now no longer available on this slave display. Time-of- Day setting must be made to the unit providing the serial Time-of-Day data. 5. If the data link is lost, the clock will revert to stand-alone local operation and the sync LED will extinguish. 6. Local timer functions continue to be available as described on the preceding page. 7. The minutes and seconds may be offset from the top of hour input closure. See manual section “Time-of-Day Offset on page 8 and “IR Remote control” section. 8. The hour, minutes and seconds may be offset from the upstream time-of-day serial data via the infra-red remote control. See manual section “Time-of-Day Offset on page 8 and “IR Remote control” section. Note: software/hardware kit is available (Radio Systems part # CT-SYNC) to update Windows PC clocks from your CT-2002 serial data stream

CT-2002 Manual Page 14 GPS Driver Additional Operating Instructions Setup Programming Refer to the dip-switch setting diagram on page 23 to program the hour offset from GMT for your time zone, to enable the automatic daylight savings time setting, and to enable 12 or 24 hour operation. Note that the unit is shipped with the factory default setting of Eastern Time Zone (5 hours behind GMT), auto daylight savings time switch-over and 12-hour operation. The analog clock dip-switch (switch #1) causes the display to flash after recovery from a satellite signal loss as an operator indication that your analog clocks have lost time and must be reset. (Digital clocks connected to the GPS Master driver will automatically update.) After adjusting the time on the analog clock (see ana- log clock operation), push the start button to cease flashing and resume normal display. Factory default for this feature is “off”. Top-of-Hour Closure GPS Master driver units (on 2”, 4” and desktop) provide a top-of-hour closure available as a C-form relay closure for 250 ms, occurring at the top of each hour. The C-form contacts are available on the rear remote control barrier strip . connector on pins 15 and 16 (last two terminals on the strip). See Remote Connection diagram p19 of this manual for connections. Connections and Installation 1. Mount the antenna on a roof or window ledge with a clear view of the sky. Avoid areas directly under microwave antenna paths, or near dense foliage. 2. The antenna plugs into the clock/receiver via a pre-installed RJ-45 Ethernet style connector. Up to 150’ of four conductor shielded cable may installed between the antenna and the receiver. This cable may be user provided, or a pre-assembled 150’ or 250’ extension cable is available from Radio Systems. Please note that for any cable run in excess of 150’, in-line balancing RS-485 convertor amplifiers, available from Radio Systems, must be installed. For wiring specifications, see the attached antenna wiring detail on page 23.

CT-2002 Manual Page 15 Operation 1. After all connections are made, apply power. The unit will take from 1 to 15 minutes to acquire the satellite data. During this initial acquisition period, and during any subsequent periods of satellite data loss, the GPS Master unit will display one of 5 error codes. These codes and their meanings are listed below. 2. After acquisition, the true time will display and will be serially relayed to any digital display units “downstream”. If data is lost at any time in the future, downstream display “data” lamps will extinguish, but these clocks will con- tinue to run on their internal time base. On satellite reacquisition, the time will be updated, and the “data” lamps re-illuminated. 3. Front panel master GPS controls cannot be used to set or change the digitally displayed time-of-day, but the time mode may be used to adjust the time on any analog clocks connected, and the START, STOP and RESET switches may be used in the timer mode. See the “Analog Clock Connection and Use” sec- tion for operating details. GPS Error Codes These two digit error codes will display in the GPS Master readout in the center two digits on unit turn-on (pre-satellite acquisition) and during any data outage. Error Code 1-Pulse Per Second Serial Data Data 01 (1 PPS line broken) not present present okay 02 (satellite acquisition lost) present present bad 03 (fire-up status - first 1 to 15 minutes) not present present bad 04 (corrupted serial data output) present not present bad 05 (no antenna connection) not present not present bad

Repeat up to 35 displays. Note: final display serial line must be terminated with a 150Ω resisitor (use terminator DIP switch on large clock.) Use a crossover RJ-45 patch cable to slave Time-of-Day and/or timer displays to downstream units. Via the IR remote control enter the program mode and select option 3 for serial time-of-day format. Select “rs1” for time-of-day only re-display from the master clock. 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 the master (first clock) in the serial chain or, if you want downstream clockcs to display remote timer as well as Time-of-Day PC Clock Input Sync Note: Software/hardware kit available (Radio Systems part # CT-SYNC) to update Windows PC clocks via USB from the CT-2002 serial data stream Radio Systems, Inc.
