Industrial short haul modems

When you need to extend RS-232 beyond the 15m limit
Westermo Short haul modem for extending RS-232 communication.

The Westermo range of industrial short haul modems ensures your serial RS-232 communications remain reliable up to 18 km / 11 miles. Our short haul modems act as point to point RS-232 line drivers and are designed to operate in harsh environments. Total galvanic isolation, transient protection and industrial level EMC immunity are standard features in Westermo modems in order to provide a rugged, robust solution for the most unforgiving environments.
