ABOUT 3938
The Model 3938 is a single-width U-Port adapter providing an isolated bit-serial highway path when used with a Type L-2 serial crate controller (SCC) such as the Model 3952 or with a serial driver (SD) such as the Model 3992 or 3994.
Higher-performance byte-serial fiber optic highways and the 3939 U-Port Adapter are recommended for new design.
