From Friday, April 19th (11:00 PM CDT) through Saturday, April 20th (2:00 PM CDT), 2024, ni.com will undergo system upgrades that may result in temporary service interruption.
We appreciate your patience as we improve our online experience.
We are developing an instrument based on a proprietary cards and a single-board-computer (SBC) in a CompactPCI chassis. We're currently using an NI GPIB-PXI card in that chassis to make it into a GPIB device, but I want to know if we can use the SBC's built-in 10/100 port and NI's GPIB-ENET to do the same thing.
Note that I don't want to control other instruments from the SBC; I want the SBC (and therefore the entire box) to behave like an instrument, to be controlled from another computer.
Thanks!
p.s. the reason I would make the GPIB interface external to the box is to save a slot; the chassis we are using is 6 slots, and we would like to leave as many slots as possible for our cards.
Like any GPIB controller, you can develop a non-controller application using the ENET. There are several examples available on the Developer Zone (http://zone.ni.com) relating to "non-controller" applications. They are typically implemented by continually polling its status for TACS or LACS state and executes IBRD and IBWRT accordingly.
