Parameters: 1.EIA RS-485 standard 2.RS-485 signals: A +, B- 3.Operating mode: asynchronous transfer, point-to-point, point-to-multipoint, two-wire half-duplex 4.Transmission media: common wire, twisted pair or shielded cable, suggest shielded twisted pair wire or private communication cable. 5.Baud rate: 300 ~ 115200bps, automatically detecte the serial signal baud rate. 6.Direction control: automatically determine direction, control data transmission direction. 7.Transmission distance: 1500 m 8.Communication protocol: transparent transmission 9.Interface protection:1500W surge protection, 15KV static protection, 2500V communication isolation, against lightning 10.Working environment: 0 ℃ ~ 60 ℃, relative humidity 5% to 95% 11.Cascade: RS485 terminal can cascade up to 256 enhanced RS485 devices. (Number of devices can be cascaded in practical application depends on 485 chip type of other equipments, general 485 chips can cascaded to 32 communication nodes, enhanced chips can cascade up to 256 communication nodes. Of course, the number of nodes in practical application related to wire, communication environment, communication distance, communication speed). 12.Power supply: DC9 ~ 24V wide range DC input voltage 13.Power consumption: static about 40mA, dynamic 60mA 14.Dimensions:82*50*32mm
