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.
Claims25
A method for use with an access control system and a remote user interface comprising:
- receiving a message from the access control system consisting of nine bits of information;
- wirelessly transmitting a message to the remote user interface that corresponds to the nine bits of information to provide a wirelessly transmitted message;
- receiving the wirelessly transmitted message;
- processing the wirelessly transmitted message to provide to the remote user interface a message consisting of the nine bits of information;
- wherein a ninth bit of information specifies a message type.
A method for use with an access control system and a remote user interface comprising:
- receiving a message from the access control system consisting of nine bits of information;
- wirelessly transmitting a message to the remote user interface that corresponds to the nine bits of information to provide a wirelessly transmitted message by converting the message consisting of nine bits of information into multiple message packets and wirelessly transmitting the multiple message packets to the remote user interface;
- receiving the wirelessly transmitted message;
- processing the wirelessly transmitted message to provide to the remote user interface a message consisting of the nine bits of information.
An apparatus for use with at least one of an access control system and a remote user interface comprising:
- an RS-485 interface to facilitate reception of nine bit messages;
- a radio frequency transmitter that is operably coupled to the RS-485 interface to facilitate transmission of messages that correspond to the nine bit messages;
- wherein the nine bit messages are either of only two types of message;
- means for converting the nine bit messages into corresponding eight bit packets to be transmitted by the radio frequency transmitter;
- wherein the means for converting is further for converting each of the nine bit messages into two corresponding eight bit packets to be transmitted by the radio frequency transmitter;
- and
- wherein the two types of message comprise a polling query type and a data transfer type of message.
An apparatus for use with at least one of an access control system and a remote user interface comprising:
- an RS-485 interface to facilitate reception of nine bit messages;
- a radio frequency transmitter that is operably coupled to the RS-485 interface to facilitate transmission of messages that correspond to the nine bit messages;
- wherein the nine bit messages are either of only two types of message;
- wherein the two types of message comprise a polling query type and a data transfer type of message;
- and
- wherein only one bit of each nine bit message identifies the type of message of that corresponding nine bit message.
A method for use with a platform comprising at least one of an access control system and a remote user interface, the method comprising:
- upon receiving a message from the platform consisting of nine bits of information:
- wirelessly transmitting a message that corresponds to the nine bits of information to provide a wirelessly transmitted message and parsing the nine bits of information to provide a group of bits that comprise a message payload and a single bit that comprises a message type identifier;
- upon receiving a wirelessly transmitted message, which wirelessly transmitted message corresponds to an original nine bits of information;
- processing the wirelessly transmitted message to provide a message consisting of the original nine bits of information.
