E363xA and E364xA: Compatibility With National GPIB I/F
Card
Question: Will the E363xA and E364xA series supplies work with National Instruments GPIB I/F card for PCs?
Answer: Yes, the National Instruments GPIB board is very configurable. However, this can cause some problems.
The National Instruments card comes set 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 IEEE488 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 in when using RS232, since RS232 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, bus mastering must be enabled on that slot. If you do not enable bus mastering,
the handshake will not work on GPIB communications.
