74CHAPTER 3: MULTIFUNCTIONAL INTERFACE MODULES

MIM-2SAE/MIM-4SAE/

MIM-8SAE Module

Introduction 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.

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