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 (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.
