IntelliTouch PC-Bus Controller (E281{A}-4025)
Verify the controller’s switch settings are as follows:
(From Bottom)
12-Bit Mode SW1 - ON
Reserved SW2 - ON
Stream Mode SW3 - OFF
Reserved SW4 - ON
Z-axis enable SW5 - ON
Reserved SW6 - ON
Reserved SW7 - ON
Reserved SW8 - ON
Next, set the controller’s Base I/O Port address with the W2 and W3 jumpers. W3
selects the high-order address, and W2 the low-order address. The values of the
settings are shown in the following table:
W3 W2
Position Value Position Value
(from top) (in hex) (from top) (in hex)
4 300 8 E0
3 (recommended) 200 7 C0
2 100 6 A0
1 000 5 (recommended) 80
460
340
220
100
To calculate the Base I/O Port address, add the values of the jumpered positions of
W3 and W2. For example, the E281{A}-4025 is usually shipped jumpered for a
Base I/O Port address of 280 hexadecimal. W3 is jumpered in the third position
(200), and W2 is jumpered in the fifth position (80). The address is the sum of
200 + 80, which is 280.
