GENERAL

The Wayside Access Gateway (A53457) converts Echelon® messages to Ethernet messages. This
lets Safetran (Siemens) equipment such as the HD/Link, use Ethernet Networks for
communications. The Wayside Access Gateway (WAG) can also convert Echelon received messages
to serial messages. This allows the system to use modems for communication between Safetran
equipment.
THE WAG IS A NON-VITAL PRODUCT. IF USED IN A VITAL APPLICATION,
EXTERNAL EQUIPMENT MUST PROVIDE VITALITY.
