The 50-pin flat SCSI connector inside the PC on the SCSI controller card.
The standard PC internal SCSI connector (the male connector) has mechanical
side levers to assist in inserting and removing the mating connector. Note that this con­
nector is similar to the one on the back of Coolscan, as shown in Figure 2.2. If for some
reason you choose not to use the internal SCSI cable provided with your Coolscan, note
that there is a wide variety of 50-pin flat SCSI connectors and SCSI cables. They are all
functionally the same, yet vary in some important ways;
1. Some cables might not have a safety key. In this case, take extra precautions to
ensure that the mating cables’ connectors are properly aligned prior to insertion.
2. Some connectors may not have Pin 1 clearly marked on the connector.
3. Some cables may have Pin 1 on the cable indicated in red.
4. Some connectors will not have mechanical side levers to assist in plugging and
unplugging the cable.
Care must be exercised when inserting and removing these 50-pin connectors,
shown in Figure 3.9, as they are rather fragile. Observe the following guidelines when
handling these connectors:
