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 ana­log 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 (both large 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 telephone
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.

Radio Systems, Inc. CT-2002 Manual

Page 16

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 con­tinue 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” sec­tion 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

Radio Systems, Inc. CT-2002 Manual

Analog Clock Connection and Use

Up to 10 Radio Systems AC-12 analog clocks can be directly connected to any
CT-2002 Master or GPS driver board. If more than 10 clocks are to be utilized,
they may be connected via the AMD-1 analog clock driver. Analog clocks con­nected to the GPS Master driver will automatically be updated for Daylight
Savings Time and Standard Time. Clocks wire via a 3-wire cable, and can be con­nected in a “home-run” or “round-robin” wiring array to the driver.

To connect analog clocks to a CT-2002 Master unit, consult the “Connections to
the CT-2002 Clock/Timer” diagram for wiring instructions. To connect analog
clocks to a CT-2002 GPS unit directly or with an AMD-1 booster driver in-line,
consult “Connections to the CT-2002 GPS Driver” diagram on page 23.

Initial Time-of-Day setting

1. Set your CT-2002 Master or GPS unit to the correct time. Press Stop/Start till
display blinks. Then press mode button 12:00:00 is displayed. This is the
“Set” position.

2. Set digital clock to future time that all analog clocks are going to be set to.
Stop=Hours. Reset=Minutes. Do Not Start Clock At This Time.

3. Connect the analog clock and start it running (if it has not started on its own)
by pushing the STOP/START button on the rear of the analog clock.

4. Stop the second hand exactly as it rests on the “12” by pushing the
STOP/START button on the rear of the analog clock again.

5. Set the hour and minute hand for a time several minutes ahead. Save time set
on frozen digital clock.

6. Repeat this process for any additional clocks in the system, setting all clocks
for exactly the same time.
