About the Board
This product is a PCI Express bus-compatible interface board with support for bus master operation and
which complies with IEEE-488.1 and IEEE-488.2. This product can be used in a PC to control
communications with devices that support the GPIB interface and read GPIB bus line data.
The GPIB-F-LPE can also analyze the signal on the GPIB bus using the built-in memory
(GPIB bus analyzer function).
This product supports a low-profile size slot and, if replaced with the supplied bracket, supports a
standard size slot, too.
You can use the supplied driver library to develop application software using any programming
language that supports the Win32 API routines (such as Visual Basic or Visual C++), or using
LabVIEW.
Features
Complies with the IEEE-488.2 standard
- As the board complies with the IEEE-488.2 standard, you can control any external device that supports
this standard.
Data transfer speed 1.5Mbyte/sec max.
- The maximum data transfer speed for communications is 1.5Mbyte/sec.
Supports bus master operation
- The bus master data transfer function enables large quantities of data to be transferred between the
board and PC without loading the CPU.
Internal 2Kbyte FIFO buffers for send and receive
- The board has separate 2Kbyte FIFO buffers for sending and receiving data, allowing both small
and large volumes of data to be transferred at high speed.
- Interface messages also use a FIFO to enable high-speed transmission.
Built-in GPIB bus analyzer function [only GPIB-F-LPE]
- The board features a bus analyzer function.
This not only allows the signals on the GPIB bus to analyzed, but also permits signal analysis to be
performed while this product is performing GPIB communications
Built-in SPAS event function
- In addition to the functions of the earlier GPIB controller (
µ
PD7210), the board also supports the
SPAS event generated when a serial poll occurs. This gives you a high level of flexibility in
constructing your system.
Internal high-precision timer
- The board includes a high-precision application timer to allow accurate time monitoring to be
performed under Windows.
Long term availability
- As the board uses a high-speed GPIB controller developed by CONTEC (compatible with the
µ
PD7210 register), reliable long term availability is ensured.
Diagnosi
s
program
- A diagnosis program is supplied to support system development. The diagnostic program can be
used to check hardware operation (interrupts and I/O addresses) and to perform simple
communication tests with connected devices.
Other
- You can read the data from the application using all control lines (with the latch function) and data
lines. [Data lines are only supported on the GPIB-F-LPE.]
