More information on controller configurations and BUSSTAT diagnostics for this controller.

The E281-4035 controller only uses four consecutive I/O ports, but it occupies 32 (0x20) consecutive I/O ports. The Base I/O address is selected by jumpers W3 and W2. In the example above, the Base I/O address is 280H (factory default).

  • (W3 value x 100) + (W2 value x 10)
  • (2 x 100) + (8 x 10) = 280H

Jumper W1 selects the IRQ. In the example above, IRQ 5 is selected.
