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

Product Description

Overview: HC**2 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**2 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 1．connection characteristic: Connection compatible EIA/TIA RS***2C, RS**5 standard 2．electrical connection: RS***2 carries the DB9 pass coupling, RS***5 carries the DB9 needle coupling, matches the wiring column 3．the working: The asynchronous half-duplex difference transmits 4．the transmission medium: Twisted pair line or shielded wire 5．transmission speed: ******5.2KBPS 6．external dimensions: *3mmX*5mmX*7mm 7．use environment: **0℃ arrives *0℃, the relative humidity is 5% to *5% 8．the transmitting range: 1, **0 meters (RS***5 end) 5 meters (RS***2 end) 9．protection rank: RS***5 connection each **0W thunderstroke surge protection.
