*On the DB25 end, pins 4,5,6,8, and 20 are NOT connected in cables sold after
9/15/01. If you are using an older F34 cable and a serial extension cable longer than 80
ft, cut pins 4,5,6,8, and 20 at the DB25 end of the F34 cable to avoid system lockups in
Windows.

F45-1, Dual Port Serial Cable
If you want to install the Base between a serial terminal and a host computer,
(as with Unix, PICK, VM, etc.), you need the Dual Port Serial Port Cable,
F45-1. This cable has three connectors: 1) Host, 2) Terminal, and 3) Scanner.
This cable is configured so that the Terminal End connects directly into the
female main port of the Terminal; the female Host End connects into the
DB25 male cable end (a cable with pins 2 and 3 crossed is assumed to have
been connected between the host terminal).
