    5-38 Chapter 5: Programming RS-232 Prefix Byte RS-232 Prefix Byte Programming mode controls the use of prefix bytes. If you use an RS-232 Prefix Byte, it is the leading character in each message sent to the host terminal or PC. Following it is the message data.

  • Page 97: Rs-232 Terminator Byte

    Chapter 5: Programming 5-39 RS-232 Terminator Byte The RS-232 Terminator Byte Programming mode controls the use of terminator bytes. If you use an RS-232 Terminator Byte, it goes at the end of the message sent to the host terminal or PC. If you included a BCC (RS-232 Parameters - 2 Programming mode), it follows the Terminator Byte and includes the Terminator Byte in the calculation.

  • Page 98: Parameter Shortcuts

    5-40 Chapter 5: Programming Parameter Shortcuts The RS-232 Terminator Byte Programming mode contains 3 shortcuts: A, B and C. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag (Hex A, Hex B, or Hex C). This eliminates the need to enter all parameters when only one needs changing.
