Parallel connector
Your computer has one parallel connector. This connector supports three standard
Institute of Electrical and Electronics Engineers (IEEE) 1284 modes of operation:
standard parallel port (SPP), enhanced parallel port (EPP), and extended capability
port (ECP).
Viewing or changing the connector assignments: Use the IBM Setup Utility
program to configure the parallel connector as bidirectional. With this configuration,
data can be read from and written to a device. In bidirectional mode, the computer
supports the ECP and EPP modes.
Do the following to view or change the parallel-connector assignment:
1. Restart the computer.
2. Press and hold the F1 key to launch the IBM Setup Utility program.
3. On the IBM Setup Utility menu, use the cursor keys on the keyboard to select

Note: When you configure the parallel connector as bidirectional, use an IEEE
1284-compliant cable. The cable must not exceed 3 meters (9.8 ft).
4. Follow the instructions on the screen to save your changes and exit from the IBM
Setup Utility menu.
Parallel connector pin-assignments: There is a 25-pin, female D-shell parallel
connector on the rear of your computer, see “Input/output connectors” on page 75 for
the location of this connector.
