Disconnect power to your board.
Set the jumper between the X4 and X5 servo to Vdd (+5 V) as shown in Figure
4-13. The jumper should cover the two pins closest to Vdd, and the third pin
next to Vin should be visible.
Plug one end of the extension cable into Port 14 of the X4 header, making sure
that the "Red" and "Black" labels along the right side of the X5 port line up with
the cable's red and black wires.
Verify that your cable is plugged in correctly by checking to make sure the white
wire is closest to the 14 label and the black wire is closest to the X4 label.
Connect the other end of the cable so that the black wire is connected to the
Parallax Serial LCD's GND pin, the red wire is connected to the 5 V pin, and the
white wire is connected to the RX pin.
Double-check all your connections and make sure they are correct.
Vdd vs. Vin jumper settings determine which power supply is connected to the X4 and X5
ports. When the jumper is set to Vdd, these ports receive regulated 5 V from the Board of
Education's voltage regulator. If the jumper is set to Vin, the port receives power directly
from the battery or power supply. WARNING!! MAKE SURE YOUR JUMPER IS SET
CORRECTLY TO Vdd OR YOU WILL PERMANENTLY DAMAGE YOUR LCD!!
WARNING!
Do not reconnect power to your board until you are positive the connections are
correct. If you make a mistake with the LCD connections, the Parallax Serial LCD will
be permanently damaged.
