One exception is when the TK50Z-FA expansion box connects to the SCSI port
{expansion box without a SCSI ID switch on the back of the box, the TK50Z-
GA has the switch). The TK.'50Z-FA expansion box must be disconnected
and the RZ55 expansion box must be connected between the external SCSI
port and the TK50Z-FA expansion box. The TKSOZ-FA expansion box has
termination resistors installed inside its box. The TK50Z-FA expansion box
must
be
installed at the end of the daisy chain. The TK50Z-GA expansion box
does not have the resistors installed and can be anywhere in the daisy chain.
