Help!?

I'm trying to get a Tektronix 4692 to work with our Iris 4D/70G.
We purchased the parallel interface but we didn't get the cable, so
I'm trying to make one.  I called the Hotline and recieved the following:

IBM Pin (DB25)	Signal		Printer Pin (Centronics)
1		Strobe		1
2		Data0		2
3		Data1		3
4		Data2		4
5		Data3		5
6		Data4		6
7		Data5		7
8		Data6		8
9		Data7		9
10		/Acknowledge	10
11		Busy		11
12		Paper End	12
13		Select		13
15		/Fault		32
16		Initiate	31
18		Ground		34
19		Ground		19
20		Ground		21
21		Ground		23
22		Ground		25
23		Ground		27
24		Ground		29
25		Ground		30

After one day they fax-ed us the above.  We informed them that we
had a DB37 connector on the back of our IRIS labeled Parallel I/F and
what they gave use was for a DB25 connector.  After 3 more days we received
the same information again only with the following headers:

4D20/IBM(DB25)	Signal Name	Printer Pin(Cent36)

We informed them that we had a 4D70g with a DB37 (again).  The nice lady at
the other end said that the DB37 had the same connections.
I tried it, it didn't work!
Has anyone done this, if you have let me know.

I can be reached at slonaklw@asdcds.wpafb.af.mil or slonaker@thor.wright.edu
