USR-WIFI232 series wifi module serial port data package description, serial port data is disordered, send it one byte by one byte, network data packet sent one packet by one packet, so now how to do data package? USR-WIFI232 series wifi module have three options for packed, satisfy with one of these request will reach this
1. The loopback test is using 1 PC to test the USR Product.You can send the data with ethernet and receive with serial port. And you also can send data with serial port and receive with ethernet. 2. Please link your Ethernet cable, 5V adapter and serial wire to your TCP M4 series module
1. Open Telnet Timeout function and description. Modules program parameter in webpage as below: Telnet timeout figure mean the time for no data timeout, 0 is not open, Max figure is 255, unit is seconds. If network side and serial port no data, the continuous time exceed Telnet Timeout set figure, after than module disconnect
As for RS232 pin ( draw forth IO port) to measure level GND reference TXD -4.92V RXD -10.21V RTS +5.36V CTS +10.65V RS232 is negative logic, TXD and RXD idle state logic is 1, voltage at 3~-15V, conform to definition. RTS: Request send, module output pin, valid mean can received CTS: Clear send, module received
