  weight of 10g.

Product Usage:

1. Connect the module to the host device using the serial
   interface.

2. Configure the serial port check bit settings by referring to
   section 3.1.1 of the user manual.

3. Select the read mode: continuous mode (default) or induction
   mode (section 4).

4. Select the LED mode: breathing lamp or decoding successful
   prompt light (section 5).

5. Scan the bar code or QR code using the module’s light and
   viewing angle, ensuring that the code is within the specified depth
   of field and contrast levels.

6. The module will provide a green light flashing prompt when a
   code is successfully recognized.

2.1 Serial Port Instruction
Users can settle the module by sending instruction from mainframe. Please make sure communicate parameter complete matching between module and mainframe. Module default serial communicate parameter: Baud rate 9600bps; No check; 8 bit data; 1 bit stop bit; No flow control.

2.1.1 Read Zone Bit

Max 255 bytes/time for zone bit reading. Command Format: Input: {Head1} {Types} {Lens} {Address} {Datas} {CRC} PS: Head1: 0x7E 0x002 bytes
Types: 0x071 byte Lens: 0x011 byte Address : 0x0000~0x00FF2 bytes, address to start reading zone bit Datas: 0x00~0xFF1 byte, Numbers of zone bit for Sequential read CRC: CRC_CCITT check value (2 bytes). Suitable for TypesLensAddressDatas; Characteristic polynomial : X16+X12+X5+1, multinomial coefficient: 0x1021, original value:0 ; For single byte, the highest bit will be calculated at first, output will be without negation. The reference code of C is as follows:
unsigned int crc_cal_by_bit(unsigned char ptr, unsigned int len) { unsigned int crc = 0; while(len– != 0) { for(unsigned char i = 0x80; i != 0; i /= 2) { crc = 2; if((crc&0x10000) !=0) //Last CRC 2 if the first one is 1so divide 0x11021 crc ^= 0x11021; if((ptr&i) != 0) //If the standard is 1so CRC = last CRC + standard CRC_CCITT crc ^= 0x1021;

} ptr++; } return crc; }
Note: users can fill 0xAB 0xCD at CRC byte when CRC validation is not required. Output: {Head2} {Types} {Lens} {Datas} {CRC} 1) Read successfully and return data PS: Head2: 0x02 0x00
Types: 0x00read succeed Lens: numbers of upload bytes Datas: 0x00~0xFF means read data. CRC: CRC_CCITT check value. Suitable for TypesLensDatas; Characteristic polynomial : X16+X12+X5+1, multinomial coefficient: 0x1021, original value:0 ; For single byte, the highest bit will be calculated at first, output will be without negation. (The reference code is the same as above) 2) CRC failed No response command 3) Unknown command response No response command
E.G.: Read address 0x000A of Zone bit 1) Read successfully and return data is 0x3E. Input: 0x7E 0x00 0x07 0x01 0x00 0x0A 0x01 0xEE 0x8A Output: 0x02 0x00 0x00 0x01 0x3E 0xE4 0xAC 2) CRC wrong Input: 0x7E 0x00 0x07 0x01 0x00 0x0A 0x01 0x11 0x22 Output : None 3) When length of command to short or more than 400ms after 0x7e 0x00, treat as unknown command. Input: 0x7E 0x00 0x07 0x01 0x00 0x0A 0x01 Output: None

2.1.2 Write Zone Bit

Max 255 bytes/time for zone bit reading. The modified content of the zone bit will be lost after power failure. If the modified content is needed after power loss,You need to save the zone bit to internal Flash(2.1.3). Command Format: Input: {Head1} {Types} {Lens} {Address} {Datas} {CRC} PS: Head1: 0x7E 0x002 bytes
Types: 0x081 byte Lens: 0x00~0xFF1 byte, means numbers of bytes of this datas, times of continuous writing. Address: 0x0000~0xFFFF2 bytes, start location of write Datas: 0x00~0xFF 1~255 bytes , dates wrote in zone bit. When configuring multiple zone bit,must follow the order of address from low to high to fill the data domains. CRC: CRC_CCITT check value (2 bytes). Suitable for TypesLensAddressDatas; Characteristic polynomial : X16+X12+X5+1, multinomial coefficient: 0x1021, original value:0 ; For single byte, the highest bit will be calculated at first, output will be without negation. The reference code of C is as follows:
unsigned int crc_cal_by_bit(unsigned char ptr, unsigned int len) { unsigned int crc = 0; while(len– != 0) { for(unsigned char i = 0x80; i != 0; i /= 2) { crc = 2; if((crc&0x10000) !=0) //Last CRC 2 if the first one is 1so divide 0x11021 crc ^= 0x11021; if((ptr&i) != 0) //If the standard is 1so CRC = last CRC + standard CRC_CCITT crc ^= 0x1021; } ptr++; } return crc; }
Note: users can fill 0xAB 0xCD at CRC byte when CRC validation is not required. Output: {Head2} {Types} {Lens} {Datas} {CRC}

3 Communication interface
GM60-S can receive database, control module and set functional parameter by TTL – 232.
3.1 Series Communication Interface
It’s default and common to connect module and mainframe(such as PC, POS) by series communication interface. Make sure communication parameter for module and mainframe are same, then it will communicate smooth and correctly.

Series Output

TTL-232 is used for series interface which suitable for most system. Required change-over circuit for RS-232.

Default Parameter as Form 3-1. Only Baud Rate can be changed.

4.2 Induction Mode

After setting, module begins to monitor brightness immediately. When scene changed, module will begin to read until time of image stabilization over.
After first successful reading or single reading time out, module will monitor brightness again after some time (changeable)
Module will cycle working as above when follow happen: module can’t find code between single read time, then it will stop reading and jump to monitor brightness.

6.6 CRC Output
CRC output (4Byte) is the value obtained after all the previous data are checked together, and is output in ASCII format.
The reference code of C is as follows:
unsigned int crc_cal_by_bit(unsigned char ptr, unsigned int len) { unsigned int crc = 0; while(len– != 0) { for(unsigned char i = 0x80; i != 0; i /= 2) { crc = 2; if((crc&0x10000) !=0) //Last CRC 2 if the first one is 1so divide 0x11021 crc ^= 0x11021; if((ptr&i) != 0) //If the standard is 1so CRC = last CRC + standard CRC_CCITT crc ^= 0x1021; } ptr++; } return crc; }
Note: If the CRC gets data of “0x1D2E”, the output of 4 bytes is 0x31 0x44 0x32 0x45 CRC output can be set by the following code:

After reading the data code, you need to scan the “save” setting code to save the data which you read.If there is an error when reading the data code, you can cancel the error reading.
For example, read a set code,and read data “A”, “B”, “C” and “D” in turn. If you read “cancel the last read bit”, the last read digit “D” will be cancelled. If you read “cancel the previous read a string of data” will cancel the read data “ABCD”, If you read “cancel modification Settings”, you will cancel the data “ABCD” and exit the modification Settings.

Cancel the last read bit

Cancel the previous read a string of data
