Description
The frequency locking of the master oscillator to the GPS-system enables the module GPS180SV to generate fixed and
optionally programmable standard frequencies with high accuracy and stability. Various oscillator options allow the cost
efficient implementation of different requirements concerning the accurracy of the outputs.
The pulse generator of GPS180SV generates pulses per second and per minute. As an option three programmable
outputs are available. The pulses are synchronised to UTC-second.
Up to four serial interfaces are available for sending timestrings. These ASCII-telegrams include information regarding
time, date and status of the GPS-receiver.
The module provides two inputs for measurement of asynchronous time events. These capture events can be read via a
serial interface.
The parameter setting of the module is done by a monitor software.

Switch outputs Optional:
Four TTL outputs can configured independently for the following modes:
- free programmable cyclic or fixed impulses
- timecode
- timer mode; three 'ON'- and three 'OFF'-states can be setup per day
The switch states can be inverted for all three outputs, the impulse lengths are
configurable in 10msec steps in a range from 10msec to 10sec.
The impulse output can be configured for all channels together to 'always' or 'ifsync'.
