4.1.7 Raw Pulse Output (RAWOUT)
The S600+ supports a single raw pulse output, typically used in prover
applications to mimic the turbine signals and send them to the prover
mezzanine card. Refer to Figure 4-16. A 1K ohm resistor is required if
the pulse rate on the prover bus exceeds 1 KHz, if there are more than
three S600+s, or if more than 20 m of cable is required.
Table 4-10 shows the RAWOUT pin connections.
