Abstract
An access control system and one or more remote user interfaces that communicate with one another via nine bit messages are able to wirelessly communicate with one another via conversion of such nine bit messages into multiple corresponding eight bit message. In a preferred approach, information from the original nine bit message that indicates a message type is segregated to one such eight bit message.
