2.5 Protocol Select Jumpers
display module between RS-232, TTL and I
are set to RS-232 mode with zero ohm resistors on the 232 jumpers. In order to place the display module in

on to the I
default slave address of 0x50 unless the I
display to TTL mode, simply remove the zero ohm resistors from the 232 or I
to the TTL jumpers. Although RS-232, USB, TTL and I
Non-USB module. For the USB module operation the USB jumpers must be in place. There are three, one
is for power. If you wish to power it up from a non-USB source, you must remove one of the jumpers. The
jumper to remove is the rightmost USB jumper as seen if Figure 20.
