I/O MINI E9/E10 JUMPERS
There has been a change to the positioning of the E9 and E10
jumper blocks on the revision E (202039E) I/O Mini board. The
current I/O Mini User's Manual, part number 000173-001 B, does
not reflect the change in positioning. Pages 5-4 and 6-5
incorrectly position E9 and E10. The correct positioning of
these jumpers are:
----- -----
| | | |
| o | | o |
| | | |
| o | | o |
| | | |
----- -----
E9 E10
E9 controls IRQ 3 for serial port #2 (see page 5-4).
E10 controls IRQ 7 for the parallel printer port
(see page 6-5).
This information only applies to revision E I/O Mini boards. The
manual correctly positions these jumper blocks for I/O Mini
revision A thru D.
