UDP commands control(192.168.0.160, port number 5000) 

I/O Command

Format: (IOx,?)

Parameter: x values [1-8]

Function: Obtain channel x I/O input status

Example: Query the first IO status: (IO1,?), return: (IO1,z)

Explanation: I/O open circuit to ground z=0, I/O short circuit to ground z=1

*Remark: When there is a state change in the x-th I/O input port, feedback information will be actively sent to the serial port and UDP client (As a UDP server, the device only sends status feedback information when the UDP client first connects)

IOALL Command

Format: (IOALL,?)

Function: Obtain the digital quantity status of all eight channels

Example1: Query all eight I/O status: (IOALL,?), return: (IOALL,z)

Explanation: Z is a character, and the values of 1-8 bits correspond to the status of 1-8 I/O channels respectively; When the hexadecimal value of z is 01h, it indicates that the first I/O is short circuited to ground, and the remaining seven are open circuited to ground; When the hexadecimal value of z is 31h, it indicates that the first, fifth, and sixth I/O channels are short circuited to ground, while the rest are open circuited to ground

RELAY Command

Format: (RYx,z)

Parameter: X values [1~8]; Z values [0-1]

Function: Control the x-th relay [on/off]

Example1: Close the first relay: (RY1,1), return: OK

Example2: Disconnect the first relay: (RY1,0), return: OK

SIR Command

Format: (SIRx,z)

Parameter: X values [A~H]; Z values [1-40]

Function: Channel x sends the z-th infrared function

Example1: Channel A sends the first infrared function: (SIRA,1), returns: OK

IRCOM Command

Format: (IRCOMx,uvw,z)

Parameter: X values [A~H]; U values [A~H]; V values [A~B]; W values [A~C]

Function: Send the string z in UVW format to the x-th (infrared) unidirectional serial port U corresponds to baud rates [A: 1200, B: 2400, C: 4800, D: 9600, E: 19200, F: 38400, G: 57600, H: 115200]; V corresponds to data bits [A: 7BIT, B: 8BIT]; W corresponds to the checksum [A; NONE, B: ODD, C: EVEN]; Z sends the content of a string, with a total length not exceeding 64 bytes (note: Non visible characters can be sent in the form of \ xxx, and the last 2 digits of xx are the hexadecimal values of non visible characters. When three special characters such as' \ x ',' (',') 'appear in the string, they must be sent in an escaped manner When encountering the character '\ x', use '\ x5Cx' to represent it; When encountering the character '(', use \ x28; when encountering the character ')', use \ x29)

Example1: Channel A sends the string TEST in 9600N81 data format: (IRCOMA,DBA,TEST) and returns: OK

COM Send Command

Format: (COMx,tuvw,z)

Parameter: X values [A~H]; T values [A~C]; U values [A~H]; V values [A~B]; W values [A~C]

Function: Send the string z in tuvw format to the x-th composite serial port; Corresponding communication protocol [A: RS232, B: RS422, C: RS485]; U corresponds to baud rates [A: 1200, B: 2400, C: 4800, D: 9600, E: 19200, F: 38400, G: 57600, H: 115200]; V corresponds to data bits [A: 7BIT, B: 8BIT]; W corresponds to the checksum [A; NONE, B: ODD, C: EVEN]; Z sends the content of a string, with a total length not exceeding 1024 bytes (note: Non visible characters can be sent in the form of \ xxx, and the last two digits of xx are the hexadecimal values of non visible characters. When three special characters such as' \ x ',' (',') 'appear in the string, they must be sent by escape When encountering the character '\ x', use '\ x5Cx' to represent it; When encountering the character '(', use \ x28; when encountering the character ')', use \ x29)

Example1: Channel A sends the string TEST in RS232 9600N81 data format (COMA,ADBA,TEST) and returns: OK

COM Receive Data Format

Format: (COMx,z)

Parameter: x values [A~H];

Function: The instruction to return data to the outside after receiving it in a string; z receives the content of a string, with a total data length not exceeding 1024 bytes

Example1: If channel A receives data '0x54 0x45 0x53 0x54', the returned instruction is (COMA,TEST)

Example2: Channel B receives data '0x52 0x45 0x4C 0x41 0x59 0x20 0x4F 0x4E', then the returned instruction is (COMB,RELAY ON), with some non visible characters in the returned instruction
