Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology 116 RS 485/232 Communication Protocol66.1. RS- 485/232 Communication Protocol: General DescriptionCommunication between the Local Site Controller LSC and the STAR READER is based on the master/slave approach. The LSC is the MASTER unit, the READERS are the SLAVE units.The LSC and the READERS communicate via a RS-485 multi drop or RS-232 connection. Each READER has its own address, enabling the LSC to approach each reader individually.6.2. Physical Layer6.2.1. Down-linkDown-link is the link from the LSC to the READERS. The link is RS-485 or RS-232 half duplex. Data rate can be one of the following: 2400, 4800, 9600, 19200, 38400 BPS. The default rate is set at 9600 BPS.6.2.2. Up-linkUp-link is the link from the READERS to the LSC. The link is RS-485 or RS-232 half duplex. Data rate can be one of the following: 2400, 4800, 9600, 19200, 38400 BPS. The default rate is set at 9600 BPS.6.3. Protocol Flow.Communication is initiated by a command sent by the LSC to the READER. The READER executes the command and responds accordingly. In a long command session, the session is concluded when the LSC acknowledges the READER within T = 50 msec.ACKIf the READERS are in sleep mode, the LSC must ensure they are awakened prior to the initialization of the session. In this case, the LSC should wait T = 50 msec before sending the main command.w
Hi-G-Tek Ltd. Microelectronics & Asset Tracking Technology 1176 RS 485/232 Communication ProtocolThere are 2 types of commands: SHORT COMMANDS and LONG COMMANDS.Short Commands: These are commands that are relevant to internal tasks at the reader level.Long Commands: These commands involve sessions with seals.The READER will respond to commands generated by the LSC within T seconds.RLSCFor short commands, response time should be: T = 50 msec.RLSCFor long commands, the LSC should return to retrieve the results after T with the appropriate GET RESULTS command.sessionT is a derivative of the type of command executed to the seals.session Acknowledge can be positive or negative. If the LSC detects a problem, Acknowledge will be negative. The READERS are designed to work in cycles. Following an internal or external trigger, a READER SESSION is generated. This is a full communication cycle going back and forth between a READER and the tags located in the READER's receiving zone. The LSC operates differently The READERs are scanned on a different time line, using the same frequency as that of the READER's cycles or greater.This protocol supports RS-485 and RS-232 communication fashions. When working with the LSC using RS-232 communication opposite only one device, address fields should be set to 0xFFFF. When using RS-485 communication in broadcast situations, the address field should be set to 0x0000.

CMND Field Structure.The command field is divided into several sections:DIR Denotes string direction. In case of a command from the LSC to the reader, it is equal to 0. PK Denotes whether the command transmitted is composed of packets or not. PK = 0 is for non-packet commands. PK = 1 is for packet commands.ERR this flag indicates an error. ERR = 0 no error. ERR = 1 Error. The first byte in the data field is the error code.CT Is the scenario command type.

DIR PKERRMTMC This field holds the same value as the Command Code of the related commands. This field makes it possible to link the response to the appropriate command.This code reflects the nature of the response. A regular response to a command has the same value as the CC (See paragraph 6.4.1.2). This flag indicates an error.ERR = 0 no error.ERR = 1 Error. The first byte in the data field stores the error code.Denotes whether the transmitted message is composed of packets. A response of 1 indicates that the message is composed of packets. If the response is 0, the message was transmitted without packets. (If PK=0 there must be 1 reserved data byte).

If the response indicates 0,the Reader uses its internal value for ADI. If not, this is the value which will be transmitted to the seals.Time&Date are the current Time and Date of the LSC.6.5.5.2.2. Execute RF Command ACK.This command involves a RF session with either the tags or seals. For that reason, the READER carries a Long Command.

SetThe Tamper command is intended solely for interrogation of tampered Seals. This command is identical to the Verify command except for the opcode which is 11h.In accordance to this, only Seals that have detected tamper status will respond. The aim of this command is to provide high priority totampered Seals in a crowded Seal environment.Set command is a command used when it is necessary to approach a large number of tags or seals. If the string becomes too large it will be split into packets. Each packet includes information for up to 8 tags or seals. This is a very critical command, as it uses internal CRC for each tag data.

Suspended set6.5.5.2.7. Soft setThe Suspended Set command is the command used when it is necessary to prepare a large number of Seals. The command functions in the same way as the SET command, the only difference being that the SET command is executed immediately,while the Seal executes the Suspended SET command automatically only after the Seal wire has been plugged into the Seal.The opcode for this command is 99h. The response is identical tothat of the SET response, but with 19h as the message type.This command has the same structure as the SET command. The difference between the two is at the seal level. The seal marks this command as an event, but doesn't reset the events memory. The opcode for this command is 9Ah. The response is identical to that of the SET response, but with 1Ah as the message type.
