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)
