This transmission module realises the interchange of TTL signals and RS485 signals, but you must know that 485 is a half-duplex communication, this communication method can achieve two-way communication, but not in both directions at the same time, must take turns alternately; that is to say, each end of the communication channel can be the transmitting end or the receiving end, but at the same time, the information can only have One direction of transmission. _x000D_ 2. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x000D_ 3. Please allow 1-2cm measuring deviation due to manual measurement. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ 1 xSignal Converter _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
