As described in other sections, a complete configuration of serial port 4
requires that you set additional jumper headers on the MVME2700 or the
transition module.
Serial port configurations for the MVME712M are illustrated in figures
1-5 through 1-10.
Serial port configurations for the MVME761 are illustrated in figures 1-12
through 1-29.
Serial Port 3 Transmit Clock Configuration (J18)
On MVME761-compatible versions only of the base board, this header
configures port 3 to either drive or receive TxC. The factory configuration
has serial port 3 set to receive TxC. On MVME761-compatible versions,
you must set J2 on the transition module to complete the configuration of
serial port 3.
Serial port configurations for the MVME712M are illustrated in figures
1-5 through 1-10.
Serial port configurations for the MVME761 are illustrated in figures 1-12
through 1-29.
