V Communication Protocol

The protocol defines the data exchanging format when ZFM-70 series communicates with upper computer.

The protocol and instruction sets apples for both UART and USB communication mode. For PC, USB interface is

strongly recommended to improve the exchanging speed, especially in fingerprint scanning device.

5.1

Data package format

When communicating, the transferring and receiving of command/data/result are all wrapped in data package

format. for multi byte , High byte in the former low byte after. For example, 00 06 is means 0006.

2 bytes

Fixed value of 0xEF01; High byte transferred

first.

Adder

ADDER

4 bytes

Default value is 0xFFFFFFFF, which can be

modified by command. High byte transferred first and

at wrong adder value, module will reject to transfer.

End of Data packet.

Package

length

LENGT

2 bytes

Refers to the length of package content

(command packets and data packets) plus the length

of Checksum( 2 bytes). Unit is byte. Max length is

256 bytes. And high byte is transferred first.
