Descriptions of the ASCII, ASCII Hex, and Binary Data Protocols

Last Update: 11/7/2018

Descriptions of the protocols are as follows:

  • ASCII Protocol: Each byte is a character. For example, if the byte sent was 0x35, it would be ASCII character 5.
  • ASCII Hex Protocol: Two bytes are used represent a single character. For example, if the device sent 0x33 and 0x35, they would be combined as 0x35 (or the ASCII character 5).
  • Binary Data Protocol: Each byte is the sum of the bits that are set within. For example, for the bits 00000101, the byte value would be 0x05. The decimal value would be 5.
