Type TSP-Link accessible
Function Yes
Usage
digio.writeport(data)

Details
The binary representation of data indicates the output pattern to be written to the I/O port. For
example, a data value of 170 has a binary equivalent of 00000010101010. Lines 2, 4, 6, and 8 are
set high (1), and the other 10 lines are set low (0).
Write-protected lines are not changed.
The reset() function does not affect the present states of the digital I/O lines.
Use the digio.writebit() and digio.writeport() commands to control the output state of
the synchronization line when trigger operation is set to digio.TRIG_BYPASS.
Example
digio.writeport(255)
Sets digital I/O Lines 1 through 8 high (binary 00000011111111).
