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:
Figures 1-8/1-9 (for the MVME712M) and Figures 1-14/1-15 (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
the MVME712M or MVME761 Transition Module sections or to the
userÕs manual for the transition module you are using (listed in the
Related Documentation appendix).
