  • Page 5: Microtec Basic Pos Protocol

    MicroTec Basic POS Protocol Data format: ECU to POS The DC-707 ECU will send a variable length packet of data prior to dispensing a drink. This packet contains Start (STX) and End (ETX) of transmission bytes as well as a PLU number in ASCII, modifiers and trailers, and a Logical Redundancy Check byte (LRC).
  • Page 6 The same modifier and trailer sequence will be sent for all pours dispensed as price level X and portion size Y. For a DC-707 ECU that supports three price levels (A, B, C) and three sizes (S, R, L), this leads to 9 distinct Modifier and Trailer sequences.

  • Page 7: Data Format: Pos To Ecu

    Data format: POS to ECU With the MicroTec Basic driver installed, the DC-707 ECU will send the above packet of data and then wait for a response from the POS system. This response may be one of two things. Either an acknowledge byte (ACK) or a negative acknowledge (NAK).
  • Page 8 DC-707 POS INTERFACE MANUAL 8 If pour without release is set, the DC-707 ECU will pour as soon as the PLU packet has been sent regardless or the response from the POS. The packet will not be resent even if a NAK is received.
