Protocole informations

Technical Description of K8056 Board serial protocol

  • Port RS232 is configure with this setting: 2400/8/n/1

  • To control the k8056 card, the correct sequence needs to be send like this:

    • Ascii code 13
    • Card address (1..255)
    • Instruction (see below), only supported now ‘S’|’C’|’T’ set/clear/toggle
    • Relay (‘1’..‘9’), 9 for all relay
    • Checkum, it is the 2-complement of the sum of the 4 previous bytes + 1.

  • Instructions:

    • ‘E’: Emergency stop all cards.
    • ‘D’: Display address of all cards in a binary fashion (LD1:MSB, LD8:LSB)
    • ‘S’: Set a relay, followed by relay # (‘1’..‘9’ in ASCII), 9 for all relay.
    • ‘C’: Clear a relay, followed by relay # (‘1’..‘9’ in ASCII), 9 for all relay.
    • ‘T’: Toggle a relay, followed by relay # (‘1’..‘8’ in ASCII).
    • ‘A’: Change the current address of a card, followed by the address (1..255)
    • ‘F’: Force all cards address to 1 (default)
    • ‘B’: Send a byte, Allows to control the 8 relays in 1 byte (LD1:MSB, LD8:LSB)
