OUTPINPDIO?
Syntax OUTPINPDIO?
Description When input/output port D of the 24-bit I/O port is set to an input port (by the execution of
the “DIN” command on page 297), 4-bit data is inputted into the 4294A through port D
(D0 to D3) and the data is read out to the external controller. If port D is set to an output
port, executing this command causes an error and the command is ignored. This command
has the same function as the READIO(16,3) command of Instrument BASIC.

OUTPINPEIO?
Syntax OUTPINPEIO?
Description When input/output port E (port C + port D) of the 24-bit I/O port is set to an input port (by
the execution of the “CIN” command on page 278 and “DIN” command on page 297),
8-bit data is inputted into the 4294A through port E (C0-D3) and the data is read out to the
external controller. If port E is set to an output port, executing this command causes an
error and the command is ignored. This command has the same function as the
READIO(16,4) command of Instrument BASIC.
