Next, install a jumper vertically at W1 to select the Interrupt (IRQ). A jumper is
supplied, but may be found in a horizontal, inactive position. See Choosing an
Interrupt (IRQ) for PC-Bus Controllers, page 25. The jumper block positions are
as follows:
Position Interrupt (IRQ)
(from left)
12
23
34
4 5 (factory set)
56
67
Remember the Base I/O Port address and IRQ values. You will need them when
updating your CONFIG.SYS file.
Next, verify the Touchscreen Type jumpers. The controller is shipped with a
jumper installed on the pins marked W4. This is the correct setting for E274 5-wire
touchscreens. If you are using an older E270 3-wire touchscreen, install the jumper
on W5 instead.
