## Description

Description: Absolute using imported chips, industrial design, anti-interference ability, while using more effective mine design can be used in the industrial field and harsh field environments, the working temperature of -40 ℃ to + 85 ℃ transmission distance up to 1 kilometer (made with 850 meters of cable F1.5 tests recommended in the 800 meters, more than 800 m, please add repeaters). The module is fully considered mine design, long-distance transmission signal 485 in the wild, the module "Connected to the ground" terminal is connected to the earth, can play a very good anti-jamming and anti-lightning effect, more secure; it can not connect with the ground when the indoor short-distance transmission. Has a 120 ohm termination resistors, shorted R0to enable the termination resistor. Package included: 5* TTL to RS485 485 to Serial UART Adapter
