A HPIB probe interface made as a quicky to debug HPIB trouble.
It uses the HP 01650-63203 isolation adapter which uses a 2x20 pin connector which is easier to put on a board, and it contains the termination network.
The device’s pin assignments are as follows:
The “ADDR” label is strange here, but it is required to exist for the inverse assembler to work. It just has a dummy assignment to an unused pod.
The STAT field has the following signal assignments:
Bit | Signal |
|---|---|
0 | ATN |
1 | EOI |
2 | REN |
3 | IFC |
4 | SRQ |
5 | NDAC |
6 | DAV |
7 | NRFD |
The combination of ATN and EOI comes out on a separate pin on the device.
