 System Confiuration Parameter 

To facilitate user’s developing, Module opens part system parameters for use. And the basic 

instructions are SetSysPara & ReadSysPara. Both instructions take Parameter Number as 

parameter. 

When upper computer sends command to modify parameter, Module first responses with original 

configurations, then performs the parameter modification and writes configuration record into Flash. 

At the next startup, system will run with the new configurations. 

  Baud rate control (Parameter Number: 4) 

    The Parameter controls the UART communication speed of the Modul. Its value is an integer N, 

N= [1, 12]. Cooresponding baud rate is 9600*N bps

 

  Security Level (Parameter Number: 5)   

The Parameter controls the matching threshold value of fingerprint searching and matching. 

Security level is divided into 5 grades, and cooresponding value is 1, 2, 3, 4, 5. At level 1, FAR is 

the highest and FRR is the lowest; however at level 5, FAR is the lowest and FRR is the highest. 

  Data package length (Parameter Number: 6) 

The parameter decides the max length of the transferring data package when communicating with 

upper computer. Its value is 0, 1, 2, 3, corresponding to 32 bytes, 64 bytes, 128 bytes, 256 bytes 

respectively. 

 System status register   

System status register indicates the current operation status of the Module. Its length is 1 word, and 

can be read via instruction

 ReadSysPara. 

Definition of the register is as follows: 

Bit Num 

15    4 

Description Reserved 

ImgBufStat 

PWD

Pass 

Busy 

Note: 

Busy

1 bit. 1: system is executing commands; 0: system is free; 

Pass

1 bit. 1: find the matching finger; 0: wrong finger; 

PWD

1 bit. 1: Verified device’s handshaking password. 

ImgBufStat

1 bit. 1: image buffer contains valid image. 

Module password 

At power-on reset, system first checks whether the handshaking password has been modified. If not, 

system deems upper computer has no requirement of verifying password and will enter into normal 

operation mode. That’s, when Module password remains the default, verifying process can be 

jumped. The password length is 4 bytes, and its default factory value is 0FFH, 0FFH, 0FFH, 0FFH.   

Should the password have be modified, 

refer to instruction SetPwd

, then Module (or device) 

handshaking password must be verified before the system enter into normal operation mode. Or 

else, system will refuse to execute and command.
