MIM-2SAE/MIM-4SAE/MIM-8SAE stands for 2/4/8-port enhanced high-speed 
synchronous/asynchronous serial interface module. In terms of function, SAE 
modules are the same as SA modules except that SAE modules support more 
protocols, for example, RS449, X.21, and RS530.

The interface attributes of SAE modules are given in the following table:
