I just bought a Wren VI SCSI hard drive ( model #94191-766) from Caber
Systems, they have provided absolutely no support. Does anyone out there
know the purposes of the nine jumpers on the back of the drive? In
particular, I need to set the SCSI id to 2. I assume most companies would
send at least a data sheet to explain the basics of installation ( not one
piece of paper from Caber Systems). Thanks to anyone who can help me.

It's a single sheet in small type with several diagrams. I won't try to reproduce the text and diagrams here, but I'll mail a photocopy to the first 3 people to ask. I have Revision C, Feb 1990. To set the SCSI logical address, set jumpers 3, 4 & 5 (counting from left where leftmost jumper is numbered 1) to the binary value of the address. Jumper installed = 1; not installed = 0. The jumpers are installed vertically. Incidentally, I've always seen the drive name spelled the way you spell it--Wren VI--but Seagate calls it the Wren 6.

In cases like this, I go to a friendly disti for data.

In > particular, I need to set the SCSI id to 2. From my manual, connector viewed from rear of drive: Terminator +- Motor start option (wait for Start Unit cmd) Power SCSI ID | +- enable parity | 4 2 1 | | ======================================= <- cct board | o o o o o o o o | | 1| 2 | | o---o o o o o o o | +---------------------------------+ pin 1 SCSI ID is binary, factory default is drive 1. If drive is not to be terminated, remove SIP resistor packs (3). If drive is terminated, insert a jumper in position 1 or 2 as shown near pin 1 above. 1 (vertical) means terminator power comes from drive. 2 (horiz.) means power comes from cable. Unmarked pin is reserved. Yes, I realize there are only 8 jumpers shown here. This is from the manual I have and it doesn't quite match the drive. I believe that one of the end pins is reserved. You'll have to orient yourself by way of knowing what the factory default jumpering is. bmw@isgtec.uucp [ ..uunet!utai!lsuc!isgtec!bmw ] Bruce Walker
