The SCSI connector inside the computer will be a 50-pin flat connector as shown in Figure 3.10. Note the position of the pin 1 and the key . There are a wide variety of 50- pin flat connectors used . They are similar yet some may have keys while others do not. Some may have Pin 1 clearly marked while others will not; and some may have mechanical levers to assist in inserting and removing connectors.

Care must be exercised when inserting and removing these 50-pin connectors . These connectors are rather fragile . Follow the rules below when dealing with these connectors.

1.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 3.9.
