Extend the USB port on the PC to a walk-through interface that is compatible with the RS-485/422 standard. The supported baud rate is up to 115200. RS-485 flow direction control is handled automatically by the onboard microcontroller without any software intervention. In addition, the module draws power from the USB port without any external power adapter. In order to prevent lightning and surge damage to converters and equipment, 600W surge protection circuit is installed on each signal line to ensure reliability and stability during long-term operation. It can be used in highway toll collection, surveillance video, building intercom, PLC, credit card access control, power collection and industrial data collection. The meaning of the front and back status indicators of U485 is as follows: RXLED: RS-485/422 signal input indication, flashing when there is data TXLED: RS-485/422 signal output indication, flashing when there is data The terminal end of U485 is defined as follows: 1.RX+: RS-422 signal input is positive 2.RX-: RS-422 signal input negative 3.GND: RS-485/422 terminal ground, connecting the earth and shield 4.TX+/D+: RS-485 signal input/output positive or RS-422 signal output is positive 5.TX-/D-: RS-485 signal input and output negative or RS-422 signal output negative Return Policy Shipping Informations Payment About us Return Policy WE PROMISE YOU CAN GET THE ITEMS YOU PAID OR REFUND.
