Pulse outputs
The pulse generator of the satellite controlled clock GPS164xHS containes three
independant channels and is able to generate a multitude of different pulses, which
are configured with the software GPSMON32. The active state of each channel is
invertible, the pulse duration settable between 10 msec and 10 sec in steps of 10
msec. In the default mode of operation the pulse outputs are disabled until the
receiver has synchronized after power-up. However, the system can be configured to
enable those outputs immediately after power-up. The pulse outputs are electrically
insulated by optocouplers (GPS164xHS) or PhotoMOS relays (GPS164/AQ/xHS)
and are available at the terminal block.
The following modes can be configured for each channel independently:
Timer mode: Three on- and off-times per day per channel programmable
Cyclic mode: Generation of periodically repeated pulses.
A cycle time of two seconds would generate a pulse at
0:00:00, 0:00:02, 0:00:04 etc.
DCF77-Simulation
mode:
The corresponding output simulates the DCF77 time telegram.
The time marks are representing the local time as configured by the user.
Single Shot Mode: A single pulse of programmable length is generated once a day at a
programmable point of time
Per Sec.
Per Min.
Per Hr. modes:
Pulses each second, minute or hour
Status: One of three status messages can be emitted:
‘position OK’: The output is switched on if the receiver was able to
compute its position
‘time sync’: The output is switched on if the internal timing is
synchronous to the GPS-system
‘all sync’: Logical AND of the above status messages.
The output is active if position is calculated AND the
timing is synchronized
Time code: The un-modulated IRIG or AFNOR signal of the built in time code generator
is made available at the respective output.
Time string: The time string of the serial port COM1 is made available at the respective
output.
Idle-mode: The output is inactive
