RS-232 and RS-485 bi-directional interface converter

Product Description

HC**1 is a RS***2 and RS***5 bi-directional interface between the converter. Simple second-line communications can be RS**5 multi-point framework for communications networks. Has been widely used in point-to-point, point-to-multipoint interface of RS**5 communication equipment such as: 1. Industrial Automation System. 2.PLC and PLD. 3. Intelligent surveillance system. 4.POS credit card machines, POS systems. 5. Data acquisition, control system and so on. HC**1 to RS***2 serial port to send the TXD and RXD receive balanced signals into RS***5 signals. No external power supply, RS**2 port directly from the power supply of 3 feet, 7 feet at the same time with a request to send (RTS), *-pin data terminal ready (DTR) to the HC**1 auxiliary power supply, automatic flow control so that you do not have to re - installation of hardware and software settings, use very simple. Performance parameters: Serial interface Interface compatible with EIA / TIA of RS**2C, RS**5 standard Transmission medium Ordinary twisted-pair Transmission distance **5Km (*****0 - ***0bps) Which 1.2Km (up to *7.6Kpbs) Power Requirements Without Joint approach RS***2: DB9F RS***5: DB9M DB9F (with five terminals) Signal RS***2: TxD, RxD, RTS, CTS, DTR, DSR, DCD, GND Work RS***5: Asynchronous half-duplex Communication protocol Transparent Operating temperature －*0℃～*0℃ Relative humidity 5%～*5%
