Digital outputs
Alarm
Semiconductor relay output, switching current up to 200 mA, open in de-energized
state.
If GPS is configured as time source and the connection to the GPS antenna is inter-
rupted for > 3 minutes, the alarm output will be closed.
Pulse
Reserved for future functions.
7.3.4
GPS input X44
The GPS interface serves to connect the “Trimble
®
Acutime™ GG” or “Trimble
®
Acutime™ 360” smart antenna with the pre-assembled cable. ibaClock only supports this
antenna type. The antenna must be connected with a point-to-point connection to the
device.
It is recommended to only use the cable which is assembled by iba. When placing the
order the required cable length must be indicated (max. 400 m). Due to the technical
specification, the use of standard antenna cables is not possible.
No separate power supply is needed for the antenna. The power supply is made via
ibaClock.
The GPS antenna receives the time signal and position data of the GPS satellites which
are in their viewing range. The GPS universal time (GPS-UTC, Universal Time Coordi-
nated) is calculated from the time signal and the runtimes. The world time UTC is calcu-
lated from the GPS-UTC by subtraction of the switching seconds.
A configuration of the GPS input is not required.
7.3.5
IRIG-B input X45
Time sources using IRIG-B time code formats can be connected via the IRIG interface
X45.
The following IRIG-B telegrams are supported by ibaClock:
IEEE C37.118
AFNOR NF S87-500
IEEE 1344
B004 + B124, B005 + B125
B006 + B126, B007 + B127
Hinweis
If the IRIG-B time code format sent by your time source is not listed above, please contact
our support team. Usually all IRIG-B time code formats transmitting the date in years are
supported.
7.3.6
Ethernet interface
The device can be connected to a computer or to a network via the Ethernet interface
X22. The web interface of the device can be accessed via the Ethernet connection.
For more information, please refer to chapter 9.2.1.
