Decode By Commands - Mindeo ES4600 User Manual

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 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.
