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).
