P2, P3: Programmable Outputs (2-pin [3.81 mm] / BNC or ST Fiber)
Electrical and Physical Configuration
Each output port may be fitted at the factory according to the following:
Electrical
Electrical Specification
Physical
TTL
CMOS/TTL (5 V) logic level driver output ports, 150 mA sink and
source. The port is fully floating and has independent electrical
isolation to 2.5 kV.
2-pin
or BNC
RS422
High Speed RS422/485 (5 V differential) output ports. The port
is fully floating and has independent electrical isolation rated
to 2.5 kV.
2-pin
HV MOSFET
Power MOSFET Switch, allowing switching of 300 VA, 100 mA
max. The port is fully floating and has independent electrical
isolation rated to 2.5 kV. Refer to Figure 11 for the suggested
wiring configurations for use with Power MOSFET switching.
2-pin
Fiber
ST fiber transmitters, compatible with ST-terminated multi-
mode fiber optic cabling. (λ=820 nm)
ST Fiber
Examples of the three connector types are given in (
Figure 6
) to (
Figure 8
);
Figure 6 – 2-pin connector
Figure 7 – BNC connector
Figure 8 – Fiber connector
If an output is not being used, it may be left unconnected. The dust cap should remain in place
on unused fiber connectors.
P2, P3 Programmable Output Options
The user may configure
P2
and
P3
to output in either inverted or non-inverted polarity:
A configurable number of pulses per second, minute, hour, or day with adjustable pulse
width and offset.
IRIG-B time code (unmodulated DCLS or modified Manchester) with optional IEEE
C37.118.1 or AFNOR NF S87-500 extensions.
Simulated DCF77 receiver time code.
Refer to the Tekron Configuration Tool Manual for further information.
