The property lost flash memory can ensure that data are not lost under power-down conditions, the model MAX3232 of electrical level transferring chip, MCU be provided
5V voltage conversions are that 3.3V voltages use for serial port module, serial network controller.MCU data receiver port RXD, data hair
Sending end mouth TXD, grounding ports GND respectively the data sending terminal mouth TXD with serial network controller, data receiver port RXD, connect
Ground port GND is connected.MCU Data ports connection network data indicator lamp LED2, for indicating the transmission state of network data,
Link ports connect network connection status indicator lamp LED1, for indicating network connection situation.The MCU possesses initiative recognition company
Abnormal function is connect, after foundation is connected, is had with the KeepAlive keep-alive probe packets of about 15s interval transmission, if even
It situations such as being connected to abnormal interrupt, then can be immediately detected, and control the serial network controller to disconnect original connection simultaneously
Reconnection.The serial network controller output port connection network transformer, avoid outside netting twine directly with serial network control
Device processed is connected, and prevents magnetic induction or electrostatic etc. from causing to damage to controller.Output port RX+ (the reception signals of network transformer
+), RX- (reception signal -), TX+ (send signal+), TX- (sending signal -) be connected with RJ45 network interface sockets.
The utility model stable and reliable operation, the serial communication that case can be become to comprehensive control device are converted to ether Netcom
