2-6-4 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 Embedded 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) Embedded Scanner turns on LED illumination to decode. The LED illumination will be turned off if
either Scan standby duration expires or Embedded Scanner succeeds in decoding. A
STOP_DECODE command (0x16, 0x55, 0x0D) can end decode process.
