Serial Port 4 Transmit Clock Configuration (J17)

In synchronous serial communications, you can configure Serial Port 4 on the MVME2603/2604 to use the clock signals provided by the TxC signal line. Header J17 configures port 4 to either drive or receive TxC. The factory configuration has port 4 set to receive TxC.

To complete the configuration of Serial Port 4, you must set the following configuration headers as well:

❏J16 (Serial Port 4 receive clock configuration)

❏J20 (Serial Port 4 transmit clock receiver buffer control)

❏J15 on the MVME712M transition module or J3 on the MVME761 transition module (Serial Port 4 clock configuration)

Figure 1-9and Figure 1-10(for the MVME712M) and Figure 1-14and Figure 1-15(for the MVME761) diagram the overall jumper settings required on the MVME2603/2604 and transition module for a Serial Port 4 DCE or DTE configuration.

For additional details on the configuration of those headers, refer to MVME712M Transition Module Preparation on page 1-14, MVME761 Transition Module Preparation on page 1-25, or to the respective user’s manuals for the transition modules (listed in Appendix D, Related Documentation) as necessary.
