Product Description
This is our newest cable, we have came up with a all in one communication cable, USB to RS485 or USB to RS422 included is a breakout board
See the user manual here http://www.plccables.com/USB-RS485-RS422.pdf
This product is designed according to industrial-grade standards, as with all of our cables that we manufacture it comes with a 30day money back and a lifetime replacement guarantee.
1. The USB cable is selected from high frequency shielded pure copper wire.
2. The RS422 / RS485 interface chip is selected from TI's original industrial-grade chip VP3082. The communication distance can reach 1.2KM. Anti-jamming performance;
3. CH340/CH341 Chipset, the communication rate can reach 2M; 4. The RS422 / RS485 output interface adopts simple isolation circuit and 600W lightning protection to further enhance anti-interference; industrial standard design, very suitable for industrial use;
The pins are arranged as follows: (the product label is marked)
2 ---------- T + (A) Positive end of RS422 / D + (A) of RS485
3 ---------- T- (B) Negative end of RS422 transmission / D- (B) of RS485
7 ---------- R + RS422 positive terminal
8 ---------- R- RS422 negative terminal
5 ---------- GND
