FAQ: Will the E363xA and E364xA series supplies work with National Instruments GPIB Interface card for PCs?

Yes, the National Instruments GPIB board is very configurable. However, this can cause some problems.

The National Instruments card comes up with EOI as the termination character. This can cause problems with instruments that use a line feed as the termination character. Commands sent to the instrument are fine; however, a timeout can occur during read-back of data. This can be fixed by changing the termination character to a line feed character, which is the IEEE-488 standard.

Another possible problem occurs with REN (Remote ENable). It does not send REN when it talks to an instrument. With some commands you may get an error that says the instrument must be in remote before you can send the command. This error will normally happen only when using RS-232 since RS-232 requires a command to put the instrument in remote. This problem can be fixed by using the National configuration software utility (ibconf), and placing a check in the box called "assert REN when SC". For more information about this issue, please contact National Instruments.

If you are using the pci-GPIB card, you must enable bus mastering on that slot for the handshake to work on GPIB communications.
