Figure 17: Optical outputs
The length of fiber-optic cables shall not exceed 2km. See Chapter 1 for optical outputs technical
information. 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 optical outputs, see Chapter
4.
2.13 Amplitude modulated outputs
RT430 has 1 amplitude-modulated output, shown in Figure 18. It always generates IRIG-B124 signal.
Figure 18: Amplitude modulated output
Use coaxial cables with an impedance of 50Ω and BNC on these outputs. See Chapter 1 for signal levels
description.
2.14 Serial port (RS232, RS422/485)
RT430 has 1 RS232 and RS422/485 serial port output with a DTE pin-layout, shown in Figure 19 to send
datagrams.
