  • Page 93 • ACK/NAK ACK/NAK Control Codes are an RS-232C communication protocol for confirming communication. When data is received, an ACK (Hex:06) response is sent to the device that sent the data. When data is not successfully received, a NAK (Hex:15) response is sent to the device that sent the data.

    8.1.4. Setting Data to be Output after Reading a Code [Serial (RS-232C)] The code reader can be configured so that after a Read is executed, its read results are automatically output using Serial (RS-232C) communications. Additional information such as print quality grade and code position coordinates can be appended to the Read result output and the format of that output can be modified.
