Clock synchronization (1PPS)
The Processing Unit has a 1PPS (one pulse per second) input for clock synchronization.
It can be selected in the operator software SIS wether the falling edge or the rising edge
of the 1PPS signal is used by the Processing Unit to synchronize the internal clock. The
1PPS signal must be minimum 1 microsecond long.
The 1PPS signal is connected to the coax connector on the CBMF board. This connection
is marked
1PPS
. If the Processing Unit has two CBMF boards the lower one must be
used for
1PPS
.
The CBMF board is equipped with an optocoupler at this input. The input series resistor
is tuned for a TTL signal (Low level<0.6 V, High level>3.2 V).
Optically isolated input signals
Note
The input signals must not be negative, that is no RS-232 signals can be used for these
inputs.
A
Input from external system
B
Processing Unit input
circuitry
The input current must be approximately 10 mA. Depending on your input signal
additional resistance must be applied to achieve the required input current.
Two examples are shown to clarify.
