4. Command String Development Information
4.1- To assist with developing command strings, the table below shows a Hex character
conversion chart
Table 4.1.1 Hex Character Conversion Chart
4.2 - An example of the proper coding technique is demonstrated below for the ìPower Onî
Command.
Hex Character Set: 6E: Power Function
00: Write Function (Note- A ì01î would indicate a read function)
00: 3

(Lower byte- Data
Hex Coded Data: 364530303030303030303031
Note- an STX (02-Hex) would be added at the start of the string and ETX (03-Hex) would be
added at the end of the string to create a complete command.
4.3- Figure 6 shows the 14 byte string formatted in Hex Characters for the ìPower On Functionî.
