5-4 Decode by commands
①
Host sends a command (0x16, 0x4D, 0x0D, 0x30, 0x34, 0x30, 0x31, 0x44, 0x30, 0x35, 0x2E) to
set Scan mode to Host.
②
Then scanner responses with the received command and a <ACK>(0x06) character, and then
change Scan mode to Host.
③
After receiving the <ACK> character, host sends a START_DECODE command(0x16, 0x54,
0x0D).
④
Scanner turns on LED illumination to decode. The LED illumination will be turned off if either scan
standby duration expires or scanner succeeds in decoding. A STOP_DECODE command(0x16,
0x55, 0x0D) can end decode process.
