•
Ethernet cable length up to 100 m (standard Ethernet). Can be increased to up to 2 km by using
fiber optic Ethernet and media converters.
•
Automatic cable length compensation compensates errors due to propagation delays on the
network.
•
Automated configuration. The possibility to upload configuration files enables easy exchange and
configuration of the hardware.
•
OTMC 100 enables redundant configurations as defined in IEEE 1588-2008. The best master
clock algorithm (BMCA) guarantees that the best clock in the system is used as the master clock.
An automatic changeover to another clock is performed if the active master clock no longer
provides sufficient time accuracy.
•
Due to its integrated NTP server functionality, OTMC 100 can also be used in networks containing
devices that are not yet ready for PTP. OTMC 100 is able to simultaneously operate as NTP
server and PTP grandmaster clock.
The following features are supported by the OTMC 100 software:
•
Time:
•
IEEE 1588-2008 version 2 support:
- Default E2E (end-to-end) and Default P2P (peer-to-peer) profile
- Power profile acc. to IEEE C37.238-2011 (OTMC 100p only)
- Power profile acc. to IEEE C37.238-2017 (OTMC 100p only)
- Power utility profile acc. to IEC/IEEE 61850-9-3:2016 (OTMC 100p only)
- One step and two step operation
- Multicast transport
- IPv4, IPv6 and layer 2
- PTP management interface
- High performance (up to 512 messages per second)
