The HUB device has 4 slave computer RS-485 serialports, and each port has reverse connect protection function, andcan work in shutdown mode. Any RS-485 port reverse connectionwill only affect its RS-485 BUS system, will not affect the normalwork of other interface connected with RS-485 system. Users canquickly determine fault port and other connected devicesaccording to the fault alarm light.Note: The connection of slave computer RS-485 serial ports of thesame HUB device is wrong connection.【LED Indicator】LED indictor light on the front panel of product, the function ofeach LED is described in the table as below.System Indication LEDLED Statue DescriptionPWRON Power is being supplied/working wellOFF Power is not being supplied/ notworking wellTXD Blinking Data is being transmittedOFF No data is being transmittedRXD Blinking Data is being receivedOFF No data is being received1~4ONPower is on the device, thecorresponding interface of D1~D4 is onthe state of data receive/transmitBlinking The corresponding interface of D1~D4is transmitting/receiving dataOFFFault alarm: Power is not on the deviceor power is on the device but thecorresponding interface of D1~D4 isreversed【Installation】
