Digio.writeport() - Keithley 708B Reference Manual

Models 707B and 708B Switching Matrix Reference Manual
Details
If the output line is write-protected using the digio.writeprotect attribute, the command is ignored.
The reset() function does not affect the present state 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.
The data must be zero (0) to clear the bit. Any value other than zero (0) sets the bit.
Example
digio.writebit(4, 0)

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)
