    You can connect up to fifteen 16-bit Differential Ultra Wide SCSI devices (internal or external) to the AHA-2944UW. If you want to combine wide and non- wide SCSI devices, you can connect up to seven 8-bit internal devices and up to eight 16-bit Wide SCSI devices (internal or external) to a single AHA-2944UW.
  • Page 5: Using The Led Connector

    Connect a DC power cable (from your computer’s power supply) to the power connector on the SCSI device. Connecting External SCSI Devices If you are connecting external SCSI devices to your host adapter, you must obtain an external SCSI cable for each external device you install.

    The default setting Default for the AHA-2944UW is Automatic. We recommend that you leave the AHA-2944UW set to its default set- ting of Automatic. If you want to manually set the Default termination setting, see Setting SCSI Termination on Yes (Enabled) page 2 for appropriate settings.
  • Page 7 The default setting is 20.0 MBytes/sec. The host adapter supports rates up to the UltraSCSI maximum of 20.0 MBytes/sec (the AHA-2944UW provides an effective maximum synchronous transfer rate of 40.0 MBytes/sec for UltraWide devices). If your device is an UltraSCSI device, you can use the maximum value of 20.0 MBytes/sec.
  • Page 8 1 GByte. To support disk drives larger than 1 GByte, the AHA-2944UW includes an extended translation scheme. This scheme supports disk drives as large as 8 GBytes under MS-DOS with a maximum partition size of 2 GBytes.
