Power Through DB9
Jumper
In order to provide power through pin 9 of the DB-9 Connector you must connect the Power Through
DB-9 Jumper labelled R17, as illustrated below. This connection can be made using a zero ohm resistor,
recommended size 0603, or a solder bridge. The
LVK204-25
allows all voltage models to use the power
through DB-9 option, see
the electrical specifications in Table 43
for voltage requirements.
Power Through DB9 Jumper
Protocol Select Jumpers
The Protocol Select Jumpers
provide the means necessary to toggle the standard LVK204-25
model
between RS-232, TTL and I2C protocols. As a default, the jumpers are set to RS-232 mode with solder
jumps on the 232 jumpers. In order to place the display module in I2C mode you must first remove the
solder jumps from the 232 jumpers and then place them on 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. Protocol tables are shown below where an `X` designates a connected
jump while an ‘O’ signifies an open connection.
