PC/II+p Board Technical Reference Manual 87
MT002615 ©1999-2001, Megatel Computer Corporation
The QTB/dxp also contains an active termination circuit for the SCSI bus, using Dallas
Semiconductor DS2107 active terminators. Jumper JMP1 on the circuit board can be installed to remove the
active terminator from the host end of the SCSI bus. This would be used to insert the host into the middle of
the SCSI bus. Without the jumper installed, the host termination is active.
The following table summarizes the connectors and headers available on a QTB/dxp transition
board. To obtain detailed information concerning the QTB/dxp board, please refer to the megatel QTB/dxp
Technical Reference documentation.
