System compatibility

GPIB-140A belongs to NI GPIB test platform.It pairs with another GPIB-140A to build fiber GPIB link,supported by NI-488.2 driver,used for long-distance shielding transmission of GPIB instruments in measurement and test systems.It is spare part for legacy test equipment overhaul.

Function

GPIB-140A is fiber-optic GPIB bus extender.It converts electrical GPIB signal into optical signal for long-distance transmission,isolates electrical noise and ground loop interference.Transparent to original GPIB program,no software modification required for test instrument control.

Installation

Mount GPIB-140A on panel or rack,tighten fixing screws.Connect GPIB instrument cable and duplex ST fiber cable,switch on AC power.Take ESD protection before installation.

Interface

‑IEEE488 GPIB connector

‑Duplex ST fiber optical port

‑AC power inlet

‑Power and link status LED indicators

Feature

GPIB-140A classic NI fiber GPIB extender.Typical faults:fiber port contamination,GPIB interface damage,power supply failure.Inspect optical port and communication before replacement.

Diagnostic

Fault phenomenon:no link,intermittent communication,low transfer speed.Check fiber cable and ST connector cleanliness,AC power supply,GPIB cable and device status LED.

Product Brief

GPIB-140A is NI fiber optic GPIB extender compliant with IEEE488.2,supporting up to 1km optical transmission,eliminating ground loop interference for long-distance GPIB instrument measurement and test systems.Mainly used for maintenance and replacement of old test equipment.ESD protection must be followed during handling.
