Tekram Technology DC-315 Series manual Installing Device Drivers, Setting the Jumpers

2.2Setting the Jumpers

DC-315U:

JP1 (LED)

SCSI Device Activity LED Indicator (JP1)

JP1 is used to indicate activity of the SCSI devices controlled by the DC-315U adapter, and should be connected to the cable leading to the Hard Drive LED on the front panel of your computer case.

2.3Setting the SCSI IDs

Each SCSI device attached to the SCSI card, as well as the card itself, must be assigned a unique SCSI ID number. SCSI ID 7 is preset to the SCSI card, giving it the highest priority on the SCSI bus.

The SCSI IDs of your peripheral devices are usually set with jumpers or with a switch on the peripheral. Refer to the peripheral manufacturer’s manual to determine the ID of each device and how to change it.

2.4Checking the Terminators on the SCSI Bus

In order to stabilize the SCSI bus, only two sets of terminators can be installed - one at each end of the SCSI bus. The DC-315 series is equipped with Active Terminators that automatically switch from Enabled to Disabled or vice versa by scanning the devices connected on the SCSI bus. So, manual termination adjustment is not required. The following explains the terminator configuration of other devices on the SCSI bus:

Note: There are two types of termination available on SCSI devices, active and passive. Active termination is strongly recommended to ensure system integrity, particularly when devices with high transfer rates are being used. A SCSI CD-ROM drive usually comes with a passive terminator. For proper termination, it is recommended that you keep this terminator disabled, i.e. avoid connect the CD-ROM drive at the end of the SCSI bus

3. INSTALLING DEVICE DRIVERS

You need to install host adapter drivers and other software before you can use the device. For more information, see the readme file of the drivers and other software installation instructions.
