standard

flat connector as shown in Figure

of the pin 1 and the
key.
There are a wide variety of 50-
pin flat connectors used

Follow the rules below when dealing with these
connectors.

Never force the connector in and out.
2.
Make sure that the connectors are aligned properly
before inserting
.
3.
Do not remove a connector from the socket by
pulling the connector out by the
cable.
Instead use a
small screwdriver to pry each of the sides
out,
a
little at a
time.
This connector is similar to the connector on the back of
the LS-10 scanner as shown in Figure
