C.4.1 Preparing an RS-232C Cable
After obtaining an RS-232C cable, check that it is wired correctly, referring
to the table in RS-232C Signal Pin Assignment on page C-5 . If you have
an IBM communication adapter cable type 1502067, you will have to
resolder the wiring at the printer end of the cable. The procedure is as
follows.
1
Remove the plastic cover from the printer end of the cable.
2
Next to each of the wires inside the cable is a bare shield wire. Solder
all these shield wires together into a single bundle.
3
Using a section of flat wire about 3 mm wide and 15 mm long,
connect the bundle of shield wires to the metal facing of the
connector. Check that the solder connections are secure.
4
Desolder wires 2 and 3, then resolder them in crossed configuration.
Solder wire 2 to pin 3 and wire 3 to pin 2. Cover the solder joints with
thermofit tube.
5
Cut wires 4, 5, 6, and 20.
6
Solder wires 5 and 6 together and connect them to pin 20. Cover the
solder joints with thermofit tube. Leave wire 4 unconnected.
7
Tape all remaining loose ends, or seal them with thermofit tube.
8
Attach the plastic cover back on.
C.4.2 Connecting the RS-232C Cable
Check that the power of both the printer and the computer is switched off.
1
Discharge yourself of static electricity by touching a metal object
such as a doorknob.
2
Plug the printer end of the RS-232C interface cable into the printer's
RS-232C connector and attach it in place.
3
Plug the other end of the cable into the computer's RS-232C interface
connector.
4
Turn on the printer.
