Viewing or changing the connector assignments You can use the built-in Configuration/Setup Utility program to configure the parallel connector as bidirectional that is, so that data can be both read from and written to a device. In bidirectional mode, the server supports the ECP and EPP modes. Complete the following steps to view or change the parallel-connector assignment: 1. Restart the server and watch the monitor screen. 2. When the message Press F1 for Configuration/Setup appears, press the F1 key. 3. When the Configuration/Setup Utility menu appears, select Devices & I/O Ports; then, press Enter. 4. Select the parallel connector; then, use the arrow keys to advance through the settings available. Note: When you configure the parallel connector as bidirectional, use an IEEE 1284-compliant cable. The cable must not exceed 3 meters (9.8 feet). 5. Press Esc twice to return to the Configuration/Setup main menu; then, select Save & Exit Setup to exit from the Configuration/Setup Utility main menu. Parallel connector There is a 25-pin, female D-shell parallel connector on the rear of your server. See "I/O connector locations" on page 51 for the location of this connector. The following table shows the pin-number assignments for the parallel connector. 13 1 25 14 Pin 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Table 4. Parallel connector pin-number assignments.
