21 1.0 INTRODUCTION This document defines the messages used by the Flashing Speed Sign (FSS) or Variable Speed Sign (VSS) to transfer information between the Central control system computer and the FSS controller. 1.1 ACRONYMS FSS DIS CRC16 Flashing Speed Sign Driver Information System 16-bit Cyclic Redundancy Check 1.2 DEFINITIONS 1.3 DATA TYPES To abstract the protocol specification from machine and operating system dependencies, the data types used within the FSS system are defined as shown in the table below. Data Type Element Size BYTE 1 8 bits of data Definition BCD 1 Binary Coded Decimal. Two decimal digits stored in 4- bit nibbles within a byte. WORD 2 A two byte unsigned integer transmitted MSB first. DOUBLE WORD 4 A four byte unsigned integer transmitted MSB first. ADDRESS 1 A byte used to identify a particular piece of communications equipment. FUNCTION 1 A byte used for describing the type of message. STRING n An array of size 'n' of a specific data type transmitted element by element starting from the element with the lowest index value. Can be ASCII coded or other binary data DATETIME 6 Date and Time stored in BCD. Contains in order of transmission: DAY (0x01 0x31) MONTH (0x01-0x12) YEAR (omit century, 0x90-0x89 = ) HOUR (0x00-0x23) MINUTE (0x00-0x59) SECOND (0x00-0x59) MAIN ROADS Western Australia Specification 709 Electronic Speed Limit Signs Page 21 of 58

22 2.0 FSS MESSAGE FORMAT There are two message formats for the FSS. A simple 9 byte packet is used for short transmissions and an extended data packet uses a variable length format as described below: 9-byte packet description. The majority of data packets between the control system and the FSS use the 9-byte format Address Function Code Data (6 bytes) Checksum (8-bit) The data field is always 6 bytes long. Where data is not used the data should be set to zero. Note that byte stuffing is NOT used for this message structure as packet length is ALWAYS 9 bytes long Variable length transmissions use a slightly different packet arrangement Address Function Code Data (variable length) CRC16 EOT Address: Function Code: Data: 1 byte binary address (0x01-0xFF) 1 byte message Function Code (0x01-0x7F) Data bytes transferred within this message. CRC16: EOT: 16-bit Cyclic-Redundancy-Check for detecting errors and validating the message. End of Transmission character (0x7E) The CRC16 is calculated on the Address, Function Code and all data bytes. Each message sent by the Control system is acknowledged with a Normal Response from the sign. In the case of an invalid message received by the sign, no response will be given to the control system. Any unimplemented function codes should NOT be used, except codes between 0xf0 and 0xff, which can be used for custom set-up functions, such as firmware uploads. These are specific to the sign manufacturer and not documented here. 2.1 CHECKSUM CALCULATION The fixed data packet requires a checksum placed at the end of the packet to make the data packet 9 bytes long. The checksum is calculated by adding the first 8 bytes and then performing a 1's complement. The result is used as the checksum. Any higher order bits above 8 bit result are discarded. The addition of ALL the bytes in the packet (including the checksum) should yield zero (for the lower 8 bits). 2.2 BYTE STUFFING PROTOCOL The variable length protocol uses a byte stuffing sequence to allow the EOT character to be used as ONLY the last character in the transmission. Fixed length packets do NOT use byte stuffing. MAIN ROADS Western Australia Specification 709 Electronic Speed Limit Signs Page 22 of 58

23 The byte stuffing will change the transmitted packet length as required by the number of occurrences of the EOT character in the original packet. In all instances within the packet, the EOT (0x7E) character is replaced with a 2-byte sequence of 0x7D and 0x5E. Further, all instances of 0x7D are replaced with 0x7D and 0x5D. Example: Original Packet E 24 7D 7E 84.. Transmitted as E 24 7D 5D 7D 5E E 2.3 CRC CALCULATION The CRC16 is calculated on all bytes within the packet, excluding the byte stuffed bytes and the EOT character (These are stripped before the calculation is done) The CRC is presented as 2 hex bytes and appears at the end of the packet before the EOT character. The CRC calculation is based on a polynomial of x 16 + x 12 + x An 8-bit character entered to the CRC generator will produce a 16-bit result. Some example results are shown: E 24 7D 7E 84 generates 0xF9E generates 0xDA58 For the purposes of clarity, the EOT character is ignored for all the following commands (where applicable), but must be included for communications to take place. Similarly the byte stuffing is not shown within the packet, but must take place to allow the EOT character to function correctly but only for variable length packets.
