Initial start-up
9.1
Basis
After switching on, ibaClock boots and the internal PLL synchronizes the system time of
the device to the GPS signal. Thereby, a precision of better than 150 ns is reached.
During the synchronization to the time source, the green LED of the particular time dis-
play is on. The LED is statically on when the synchronization has been finished and the
source is ok. This process usually takes approx. 3 minutes.
If the device is ready for operation and the GPS is stable, it sends the time signal to the
connected ibaPDA system via the FO output. ibaClock always sends the UTC time.
If the GPS signal fails, the internal clock of the device continues to set the time signal. In
this process ibaClock provides a stability of < 0.150 ppm for temporary signal failures. If
the GPS signal fails for a longer time (days), deviations of approx. 30 ms are possible
per day between two systems which are synchronized with ibaClock.
The device can be configured via a web interface.
The following functions are available:
Diagnosis of device status and GPS signal reception
Network settings
Creating passwords
Firmware update
For the access to the device by ibaPDA, a bidirectional FO connection from the ibaPDA
computer to the device is required.
The access to the web interface of the device can also be carried out via the bidirectional
FO connection or via an Ethernet or USB connection.

Ethernet interface
The access to the web interface of the device can be carried out via the Ethernet con-
nection.
Each ibaClock device has a unique MAC address for the network identification.
Tip
You can find the MAC address on the type label on the backside of the device.
