Serial Port 4 Clock Selection (J8/15/16)

1-20
The MVME1600-011 is shipped from the factory with Serial Port 4
configured for asynchronous communications (i.e., the internal clock is
used). Port 4 can be configured for synchronous communications as well.
It can either drive (using the internal clock) or receive (using an external
clock) the Receive and Transmit clock signals. To select synchronous
communications for the Serial Port 4 connection, install jumpers on
headers J8, J15, and J16 in one of the configurations shown below.
