The P arallel I/O Mode A (Option 005 Only)
The E5100A/B Option 005 has an Input-4 Bit/Output-8 Bit I/O port. The following is a
description of how to use the Option 005 I/O port from a B ASIC program.
Data Output (4 Bit)
Y ou can use the following methods to output data:
F or Instrument B ASIC, use the WRITEIO statement.
WRITEIO 15,2; data
F or HP B ASIC use an GPIB command OUT8IO.
OUTPUT @E5100;"OUT8IO "; data
Data Input (8 Bit)
Y ou can use the following methods to read inputted data:
F or Instrument B ASIC, use the READIO statement.
Data=READIO(15,2)
F or HP B ASIC use the GPIB command INP8IO? or OUTPINP8IO?.
OUTPUT @E5100;"INP8IO?" Output data from the I/O port directly .
ENTER @E5100;Data The return value is 4 bit data.
Module 5-2. Reading Input Data
Or
OUTPUT @E5100;"INP8IO" R ead data from the I/O port to the memory and output it from the
memory .
OUTPUT @E5100;"OUTPINP8IO?"
ENTER @E5100;Data The return value is 8 bit data with 0s in its upper 4 bits .
