Input parameter ：  hCom-- Handle  Addr － The first working parameter address needs to be configured, range from 2 to 255 ...
  • Page 9 Return results: the result is zero, which shows the action is correct, others are wrong. Explanation ： it’s only used for multi-ports reader(NFC-9812,NFC-9814 etc.). User can operate the designated antenna and do reading, writing, kill operating for specific tag. This function is not valid for single ports reader.
  • Page 10 12、SetWorkAntenna Function prototype ： short SetWorkAntenna (HANDLE hCom, unsigned char Antenna) Function explanation ： Configure the working antenna(channel) for multi-port reader Input parameter ：  hCom—Handle bit mask mode, If D0-D7 is ‘1’, which indicates antena1~8  Antenna—Configured antenna, can work. If it’s zero, the corresponding antenna doesn’t work. Return results: the result is zero, which shows the action is correct, others are wrong.
  • Page 11  Mark— Relay bit mask needs to be operated; D0 is for operating”relay 1”. If D0 value is”1”, it means the state value will affect the change of reply state. If the value is “0”, then there is no impact. The definition for D1-D3 is the same as D0. ...
