Protocol Select Jumpers
The Protocol Select Jumpers, pictured below in
figure 15
, provide the means necessary to toggle the
display module between USB power and external power. As a default, the jumpers are set to USB mode
with solder jumps on the USB jumpers. In order to place the display module in external power mode you
must first remove the leftmost solder jump from the USB jumpers, as shown in figure
15
. The display cannot
be used in RS232, TTL, or I2C mode.
