• Send_BinaryDescription:Send out the command string by fix length, which is controlled by the parameter “iLen”.The difference between this function and Send_cmd is that Send_Binary terminates thesending process by the string length “iLen” instead of the character "CR"(Carry return).Therefore, this function can send out command string with or without null character underthe consideration of the command length. Besides, because of this function without anyerror checking mechanism (Checksum, CRC, LRC... etc.), users have to add the errorchecking information to the raw data by themselves if communication checking system isrequired. Note that this function is usually applied to communicate with the other device,but not for ICP DAS DCON (I-7000/8000/87K) series modules.Syntax:[ C ]WORD Send_Binary (char port, char szCmd[ ], int iLen)Parameter:port :szCmd :iLen :: [Input] 1=COM1, 2=COM2, 3=COM3..., 255=COM255.[Input] Sending command string[Input] The length of command string.Return Value:NoneExample:int m_length=4;char m_port=3, char m_szSend[40];DWORD m_baudrate=115200;m_szSend[0] = '0';m_szSend[1] = '1';m_szSend[2] = '2';m_szSend[3] = '3';Open_Com(m_port, m_baudrate, Data8Bit, NonParity, OneStopBit);Send _Binary(m_port, m_szSend, m_length);Close_Com (m_port);Remark:LinPAC-8x4x SDK:48
