Product Related compatible with RS-232C and RS-485 standard.convert RS-232 signal to RS-485 signalIt uses a particular pump to gain power from RS-232 signals (RTS, DTR, TXD) without initializing the RS-232 series interface. An internal transceiver and particular circuit automatically controls the data stream direction instead of handshake signals (such as RTS, DTR, etc.). When works in RS-232 half-duplex mode, the software keeps the same function under RS-485 without any change. The transmission rate of 300-115200bps is capable of applying between host computers, host computer and its external equipments and forms point to point, point to multi-points network.It is widely used in industrial automation, door safe, all-in-one-card, car parking, ATM, bus charge, eatery sell out, staff attendance management, and highway toll gate, etc.Interface: Compatible with EIA/TIA RS-232C standard and RS-485 standard.Electronic interface: At the side of RS-232 is a DB9 female (hole-type) connector. At the side of RS-485 is a DB9 male (needle-type) connector, with connection board.Working mode: Asynchronous, half-duplex, differential transmission.Transmission media: Twisted-pair or shielded twisted pair (STP).Transmission rate: 300-115200bps.External dimension: 95mm*33mm*17mmWorking environments: -25 degC to 70 degC, relative humidity 5% to 95%.Shipping Our shipping cost includes the cost of the packaging box, the materials used to protect the product and/or all other materials used during the processing of the product, residential shipping fee, and handling fee.
