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.
