Details
This function writes to the digital I/O port by setting the binary state of each digital line from an integer
equivalent value.
The binary representation of the value indicates the output pattern to be written to the I/O port. For
example, a value of 63 has a binary equivalent of 111111 (all lines are set high); a
data
value of 42
has a binary equivalent of 101010 (lines 2, 4, and 6 are set high, and the other 3 lines are set low).
An instrument reset does not affect the present states of the digital I/O lines.
All six lines must be configured as digital control lines. If not, this command generates an error.
Example
:DIG:WRIT 63
Sets digital I/O lines 1 through 6 high (binary
111111).
