Important Notes

WARNING: Do not allow the underside of the SCSI2SD come into contact with any conductive surfaces. Doing so may result in damage to the SCSI2SD, damage to your computer's power supply, or fire.

Power

5V power can be supplied by a standard disk drive power connector, or via a micro-usb cable. It is safe to connect both sources of power simultaneuously.

Active Terminator

The terminator can be disabled by removing the 2 resistor packs. When re-inserting the resistor packs, be sure to align the printed dot on the resistors with the board markings.

Most SCSI host controllers provide the power required to run the terminators via the 50-pin cable. For those controllers that fail to provide termination power, the J3TERMPWR jumper may be closed to provide such power.

Providing termination power via J3 only works when powered via a standard disk drive power connector. A USB cable cannot provide sufficient current, and so the USB 5V line is not connected to J3.

Hot Swap

Requires firmware version 4.0 or above.

See Hot Swap for details on modifying old SCSI2SD boards to support hot swap.

Updating the firmware

  • Obtain the latest firmware file and scsi2sd-util utility from codesrc.com.
  • Disconnect or turn off ALL sources of power from the SCSI2SD. Any connected SCSI host controller or devices must be turned off.
  • Run the scsi2sd-util line utility.

Execute permissions are required on Mac OSX and Linux

sudo chmod a+x scsi2sd-util
  • Select "Upgrade Firmware" from the scsi2sd-util File menu, and select the firmware file. Click OK.
  • Connect the USB cable.

Setting the SCSI ID

The SCSI2SD is configured over the USB interface.

  • Obtain the scsi2sd-util utility from codesrc.com.
  • Execute permissions are required on Mac OSX and Linux
chmod a+x scsi2sd-util
  • Connect the SCSI2SD via the USB cable, and then run scsi2sd-util

Root priviledges may be required on Linux.

sudo scsi2sd-util
