2.2.1 Legacy Data Connector Jumpers
To reverse pins two and three of the
Power/Data Connector
=
remove the zero ohm resistors from the
symbol and place them on the jumpers labeled with the
X
symbol. This will allow you to transmit on pin two, and receive data on pin three instead of the default
Legacy Data Connector Jumpers, labeled with the
of receiving on pin two and transmitting on pin three of the
Power/Data Connector.

2.3 Protocol Select Jumpers
The
Protocol Select Jumpers, pictured below in
?gure 17
, provide the means necessary to toggle the
display module between RS-232, TTL and I2C protocols. As a default, the jumpers are set to RS-232 mode
with zero ohm resistors on the 232 jumpers. In order to place the display module in I2C mode you must
?rst remove the zero ohm resistors from the 232 jumpers and th
en solder the resistors on to the I2C jumpers.
The display will now be in I2C mode and have a default slave address of 0x50 unless it has been changed.
Similarly, in order to change the display to TTL mode, simply
remove the zero ohm resistors from the 232
or I2C jumpers and solder them to the TTL jumpers.
