● Controls a LAN instrument from the GPIB bus. Adapts LAN instruments for GPIB Test Systems. ● Runs from any GPIB system. Transparently passes all commands to the companion LAN instrument. ● AutoFind feature simplifies instrument linkage. Eliminates changing IP addresses. ● Internal VXI-11 client talks to any VXI-11.3 instrument. Works with most LAN instruments. ● Aids in replacing failed GPIB instruments. Saves instrument replacement costs and helps reuse existing test software. ● Add newer LAN instruments to GPIB systems. Extends the number of instruments that will work in a GPIB test system. ● Internal HTML server handles 4865 configuration. Easy configuration from any computer or web browser.
ICS's 4865 is a GPIB-to-LAN Instrument Interface that enables a VXI-11.3 compatible LAN instrument to be controlled from a GPIB Bus. Using the 4865, GPIB applications running on a computer can transparently interface to a LAN-based instrument just as if it were a GPIB Instrument. The 4865 converts 488.1 GPIB commands into the equivalent VXI-11 RPC and sends them to the instrument. Device messages are transparently sent to the instrument and instrument replies are returned to the GPIB Controller, just like a GPIB instrument.
The 4865 solves the problem of how to interface an instrument with an Ethernet interface to the GPIB bus. The 4865 adds a GPIB interface to VXI-11.3 compatible LAN or LXI instruments that do not have a GPIB interface. Applications include replacing obsolete or failed GPIB instruments with a newer instrument that may not have a GPIB interface or just adding a new LAN instrument to a GPIB bus system.
The 488-USB meets IEEE-STD-488.1 with the following capabilities
AH1, SH1, C1, C2, C3, C4, and C9

488 Bus Performance
Long term GPIB transfer rates are limited by the LAN data transfer rate, the Client-computer performance, the GPIB controller and the LAN instrument or device. Internal delays vary with the amount of data transferred and 4865's activity when the message was received.
Short term transfer rates
GPIB to 4865
>20 kbyte/s.

Companion Instrument
The 4865 supports single instrument that is VXI-11.3 and IEEE-488.2 compatible.
System Requirements
Computer with an IEEE-488.2 GPIB Controller. Device messages must be terminated with the IEEE-488.2 new line terminator (linefeed with EOI asserted) or with just EOI asserted if the LAN instrument does not require a terminator.
Computer with an IEEE 802.3 LAN interface and a web browser for configuring the 4865.
Internal WebServer
The internal WebServer provides HTML web pages for viewing and setting the 4865's network settings.
