36 Appendix A - Configuring Your Controller
AccuTouch PC-Bus Controller (E271-141)
Verify the controller’s switch settings are as follows:
(From Top)
12-Bit Mode SW1 - ON
No calibration data on reset SW2 - ON
Stream Mode SW3 - OFF
Filtered Mode SW4 - 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
setting are shown in the following table:
W3 W2
Position Value Position Value
(from top) (in hex) (from top) (in hex)
1 000 1 00
2 100 2 20
3 (recommended) 200 3 40
4 300 4 60
5 (recommended) 80
6A0
7C0
8E0
To calculate the Base I/O Port address, add the values of the jumpered positions of
W3 and W2. For example, the E271-141 is usually shipped jumpered for a Base
I/O Port address of 280 hexadecimal. W3 is jumpered in the 3rd position (200),
and W2 is jumpered in the 5th position (80). The address is the sum of 200 + 80,
which is 280.
