2.10 TTL Electrical Outputs
RT430 has 4 electrical output, 2 screw connector, and 2 BNC connector. One output of each connector type
is insulated, as Figure 14 shows.
Figure 14: TTL level electrical outputs
See Chapter 1 for more description of signal levels and maximum charge.
The type of signal at each output can be configured through a Web Interface to generate IRIG-B004, DCF77,
1PPS, 1PPM, 100PPS, or any custom-defined low frequency, from 1 pulse-every-two-seconds to 1 pulse-
per-day. It is also possible to configure the outputs to generate daily set-time pulses. The polarity of the
signal can also be configured. For details on the configuration of TTL-Level electrical outputs, refert to
Chapter 4.
2.11 Open-collector electrical outputs
RT430 has 2 open-collector electrical outputs, shown in Figure 15.

See Chapter 1 for description of signal levels and maximum charge.
The type of signal at each output can be configured through a Web Interface to generate IRIG-B004, DCF77,
1PPS, 1PPM, 100PPS, or any custom-defined low frequency, from 1 pulse-every-two-seconds to 1 pulse-
per-day. It is also possible to configure the outputs to generate daily set-time pulses. The polarity of the
