2.8 Serial Communication Ports
The 5 serial ports of the VM162/VM172 are based on the 4 SCCs and 1 SMCs of the 68EN360. These
multiprotocol serial ports can be physically translated to the different standards due to application spe-
cific demands. A view of the range of front panels available for the VM162/VM172 can be found in Fi-
gure 1.1 of this manual.
Figure 2.2 MC68EN360 Channel Assignment
This translation between the ‘raw’ 68EN360 signals and ready configured port on the front panel is very
flexible on the VM162/VM172 by using SI and SC piggybacks or even CXMs. 5 configured serial ports
are available on the front panel connectors.
The Table on the following page shows the availability of the various logical serial ports on the internal
interfaces for physical configuration.
