Synchronization Of Data Acquisition; Busy List Execution Status - Scanlab RTC6 PCIe Board Installation And Operation Manual

Synchronization of Data Acquisition

If several bits are simultaneously transferred as data
words (and not independently from each other) by
the 16-bit digital output port or the 16-bit digital
input port, then the LATCH OUT signal or SYNC OUT
signal should be used for synchronization of data
acquisition.
The LATCH OUT signal (a 5 µs pulse, active-HIGH) is
outputted at pin (33) as a trigger signal for acquiring
the output values of the 16-bit digital output port.
The RTC6 PCIe Board automatically generates the
LATCH OUT signal when the output value at the
16-bit digital output is written. The output value
should be read out with the rising edge of the
LATCH OUT signal. The rising edge occurs 5 µs after
the value has been outputted at the 16-bit digital
output, see Figure 23.
To synchronize data acquisition at the 16-bit digital
input port, a SYNC OUT signal (a square wave with
5 µs pulse length and 10 µs period) at pin (34) is
continuously outputted. Value changes at the 16-bit
digital input port should be made with a falling edge
of the SYNC OUT signal. The
RTC6 PCIe Board always accepts the currently
provided value with the rising edge of the SYNC OUT
signal, see Figure 23.
The synchronization signals LATCH OUT and
SYNC OUT are referenced to GND
current load is 10 mA.
