RS-485 is a kind of devices (up to 32) to communicate at half-duplex on a TXD+,TXD-, plus a ground wire (more on that later), at distances up to 1200 meters (4000 feet)

DB9 RS485 cable Converts RS-485 to RS-232 to let laptop or computer which mounted RS232 port to communicate with remote devices

RS-485 standard is only a physical layer standard. It defines the electrical characteristics of the transmitter and the receiver.

We use FTDI chips FT232RL plus SP485E together to achieve the function that can fit the different requirement from the customers.

If your devices need different voltage such as 5.5V 3.3V, also we can relayout

The pcb board to customized for you.

The cable length can be chose usually 1M to 3M.

We use pure copper and PVC coat for this (D sub)DB9 RS485 cable .
