ETH 2 – ETH 6: Ethernet Communication Ports (RJ-45/ST Fiber Connector)
The Ethernet communication ports (ETH2 – ETH6), feature an RJ-45
connector that supports 10/100 Mbps, Auto MDI-X and Auto
Negotiate, or ST Fiber (100 Mbps) connectors (if Fiber option is
ordered). These ports include indicator LEDs which convey Link (LNK)
and Activity (ACT) status for the associated port.
Note:
ST Fiber Ethernet ports are not an orderable option for the NTS 03-G+ 4 port and 6 port
options with the advanced OCXO oscillator.
PRP: Parallel Redundancy Protocol
The NTS 03-G+ supports Parallel Redundancy Protocol (PRP) on ports ETH2 and ETH3, and when
fitted with the 6-port option, ETH5 and ETH6. When enabled via the Tekron Configuration Tool,
the ports ETH2 and ETH3, or ETH5 and ETH6, are paired and operate as a single redundant
interface. PRP support requires the purchase of a PRP license from Tekron.
PRP operation is compliant with IEC 62439-3 (2016) and supports PTP master or slave operation
in IEEE 1588-2008 default profiles or C37.238 power profile.
Note:
At no time will the NTS attempt to operate as an Ethernet router, switch or hub.
P6 – P9: Programmable Output (50 OHM BNC connector/ ST Fiber connector)
These ports can be ordered as either four BNCs (copper, 5 V, 150 mA) or as four ST Fiber
transmitters.

Figure 18 – ST Fiber Connector
These ports provide high drive, isolated TTL outputs. Each output can be uniquely programmed
through the Tekron Configuration Tool. All ports are electrically isolated from the main clock.
The outputs are paired P6 and P7 as one pair and P8 and P9 as the second pair. Each pair shares
a common reference and power supply.
