2-7-3 Example 3: Decode by commands

Case1: Decode after awakening scanner from Sleep Power state
① Host sends a <NUL> character (0x00).
② After 25 ms, Host sends a command (0x16, 0x4D, 0x0D, 0x30, 0x34, 0x30, 0x31, 0x44, 0x30, 0x35,
0x2E) to set Scan mode to Host.
③ Then scanner responses with received command and a <ACK> character (0x06), and then change
Scan mode to Host.
④ After receiving the <ACK> character, Host sends a START_DECODE command (0x16, 0x54, 0x0D).
⑤ Then scanner turns on LED illumination and decode. The LED illumination will be turned off if either
Standby duration expires or scanner succeeds in decoding. A STOP_DECODE command (0x16,
0x55, 0x0D) can end decode process.
