HMIM-4SAE/HMIM-8SAE
Introduction
The 4-port SAE module (HMIM-4SAE) and 8-port SAE module (HMIM-8SAE) are enhanced high-speed
synchronous/asynchronous serial interface modules. 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.
