This is the Cable Interface Card (Hiway 1) for the Basic Controller, Extended Controller, and Reserve Controller Directors. It works along with with the Hiway #2 card to provide the Hiway Interface for these devices.

This is the most recent version of the Hiway 1 card, prior to the introduction of the Universal Controller. This newer version of the card has enhancements for handling hardware failures and Hiway communication errors. Because of these improvements, we recommend choosing the -006 version of the Hiway 1 board when ordering a replacement.

This card has 2 BNC connectors on the card edge for connection of the Hiway A and Hiway B cables. The card contains no LEDs.
