AccuTouch Serial Controller (E271-140)

Verify the controller's switch settings are as follows:
For:
9600 Baud
4800 Baud
2400 Baud (recommended)
300 Baud
8-bit Data
Binary Mode
Filtered
Stream Mode
2400 baud is recommended to limit the excessive amounts of data at higher baud
rates.
Next, verify the Touchscreen Type jumpers. The controller is shipped with a
jumper installed on the pins marked W1. This is the correct setting for E274 5-
wire touchscreens. If you are using an older E270 3-wire touchscreen, install the
jumper on W2 instead.
