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. The SAE modules are the same as
the SA modules except that the SAE modules support additional protocols, for example, RS449,
X.21, and RS530.
