Serial Port 4 Transmit Clock Configuration (J17)

1-10
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 1-15 (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
