Connecting the Printer to the Computer

After you procure an RS-232C cable, check its wiring against the pin assignments shown in
page section B.1.2 Interface Signals on page
adapter cable type 1502067, use the procedure below to solder the wiring at the end (printer
side) of the cable:
1 1 1 1
Unscrew the plastic cover at the end (printer side) of the cable.
2 2 2 2
A bare shield wire is provided for each wire in the cable. Solder all shield wires
together into a single bundle.
3 3 3 3
Connect the bundled shield wires to the connector metal face using a piece of flat
cable about 3 mm wide and 15 mm long,. Make sure that the soldered connections
are secure.
4 4 4 4
Unsolder wires 2 and 3, then resolder them in a crossover configuration. In other
words, solder wire 2 to pin 3 and wire 3 to pin 2. Cover the solder joints with a
thermofit tube.
5 5 5 5
Cut wires 4, 5, 6, and 20.
6 6 6 6
Solder wires 5 and 6 together and connect them to pin 20. Cover the solder joints
with a thermofit tube. Leave wire 4 unconnected.
7 7 7 7
Tape all remaining loose ends together, or seal them with a thermofit tube.
8 8 8 8
Screw the plastic cover back on the cable end.
Make sure that both computer and printer are powered off.
1 1 1 1
Discharge static electricity from your body by touching a metal object such as a
doorknob.
2 2 2 2
Plug the end (printer side) of the RS-232C cable into the printer's serial interface
connector and screw it on securely.
3 3 3 3
Plug the other end of the cable into the computer's serial interface connector.
4 4 4 4
Power on the printer.
5 5 5 5
The printer's parameters are set at the factory as follows:
Baud rate = 9600 bps, data bits (character length) = 8, stop bits = 1, parity = none
The two RS-232C protocols are XON/XOFF and DTR. The printer executes both of
these protocols simultaneously, using positive logic for DTR.
