Connecting the Base with Serial Wedge
The 2020 uses TTL signal levels to wedge into an RS-232 serial network. Use
only 2020 serial wedge cables to prevent damage to the base. Refer to Con-
necting the Base with RS-232 Serial Port on page 2-8 to set the baud rate and
communications protocol.
1. Turn off power to the computer.
2. Disconnect the existing serial cable from the computer.
3. Connect the appropriate interface cable to the base. Make sure the cables
are secured in the wireways in the bottom of the base and that the base sits
flat on a horizontal surface.
Note: For the base to work properly, you must have the correct cable for your
type of computer.
4. Plug the serial connector into the serial port on your computer. Tighten the
two screws to secure the connector to the port.
