GPIB-FL2-USB High Speed IEEE-488.2 I/F Micro Converter for USB2.0

Micro USB-to-GPIB converter that adds IEEE-488.1/488.2 communication to any PC USB port — no expansion slot required. Bus-powered with a 1.8m USB cable included, 1.5 Mbyte/sec transfer rate, configurable as controller or slave, and compatible with Windows and LabVIEW via drivers available from Contec.

A micro converter that turns any PC USB port into a fully functional GPIB interface — IEEE-488.1/488.2 compliant, bus-powered, and ready to connect directly to GPIB-equipped instruments using the included 1.8m USB cable. Configurable as controller or slave, with Windows and LabVIEW driver support available from Contec.

The GPIB-FL2-USB connects to any available USB port and immediately exposes a GPIB interface compliant with IEEE-488.1 and IEEE-488.2 standards. Transfer rates reach 1.5 Mbyte/sec, and the unit can be configured to operate as either a master controller or a slave — providing full flexibility for both instrument control and system integration roles.

The GPIB-FL2-USB includes dedicated buffer memory — 2KB for transmission and 2KB for reception — to reduce CPU overhead during data transfer. This allows the host PC to handle other tasks while the unit manages data queuing independently, improving overall system throughput in automated test and measurement applications.

• 2KB transmission buffer — offloads outgoing data queuing from the host CPU, enabling smoother data flow during continuous output operations.
• 2KB reception buffer — holds incoming data independently, reducing the risk of data loss during burst reception from instruments.
• SPAS event function — supports Serial Poll Automatic Status (SPAS) events when operating in slave mode, enabling flexible multi-device system architectures.
• Contec GPIB controller — self-developed controller with uPD7210 register compatibility ensures broad instrument compatibility and long-term availability.

• Windows driver library — downloadable from Contec website; enables application development in C, C++, C#, and VB.
• GPIB communication driver for LabVIEW — supports integration with LabVIEW-based test and measurement environments.
• Diagnostic program — confirms hardware operation and performs basic communication tests with connected GPIB instruments.
