Serial commands

  • Communication parameters – 8 Data, 1 Stop, No Parity, Baud Rate – 9600 bps
  • Command for receiving the relays status:
    • Send “ask//”.
    • The answer is two bytes – byte 1 and byte 2. Byte 1 represents relays from 1 to 8. MSB of byte 1 is Relay 1 and LSB of byte 1 is Relay 8. Byte 2 represents relays from 9 to 16. MSB of byte 2 is Relay 10 and LSB of byte 2 is Relay 16.
    • Example:
      • answer 1: 00 -> relays from 1 to 16 are OFF.
      • answer 2: 255(dec) 255(dec) -> relays from 1 to 16 are ON.
      • answer 3: 81(dec) 81(dec) -> Relays 1,8,9,16 – ON, the rest are OFF.
  • Commands for single relay setting:
    • “01+//” – Relay 1 is switched ON
    • “01-//” – Relay 1 is switched OFF
    • “02+//” – Relay 2 is switched ON
    • “02-//” – Relay 2 is switched OFF
    • ……
    • ……
    • “16+//” – Relay 16 is switched ON
    • “16-//” – Relay 16 is switched OFF
  • Commands for all relays setting:
    • “on//” – All relays are switched ON
    • “off//” – All relays are switched OFF
  • Command for many relays setting
  • Send sequentially:
    “x” – as a char
    a – as HEX number. a[0;FF]. This number correspondence with relays from 1 to 8. The MSB is relay 1.
    b – as HEX number. b[0;FF]. This number correspondence with relays from 9 to 16. The MSB is relay 9.
    “/” – as a char. This is the first part of the delimiter
    “/” – as a char. This is the second part of the delimiter
    Example (a=1A(hex) and b= 05(hex) )
    “x” 1A 05 “/” “/”
    1A(hex)=00011010(bin)
    05(hex)=00000101(bin)
    Relays 1,2,3,6,8,9,10,11,12,13,15 – switched OFF
    Relays 4,5,7,14,16 – switched ON    Note that there must be minimum 5ms interval between each two commands !
