Product introduction

 RS232 / RS485 converter between the two-way interface converter, used in the host computer, master

Between the machine and the microcontroller or peripherals constitute a point to point, multipoint remote multipoint communication network to achieve multi-machine

Answering communications and communications, widely used in industrial automation and control systems, card, access control system, stop

Car system, self-service banking system, bus charging system, canteen Shoufan system, staff attendance

Management system, highway toll station system and so on.

RS232 / RS485 converter, capable of converting the TXD and RXD signals of the RS-232 serial port into two scales

Half duplex RS-485 signal. No external power supply, can be directly from the RS-232 port 3 feet theft, with

Request to send by 7 feet (RTS), 4-pin data terminal ready (DTR) to RS232 / RS485

Auxiliary power supply, automatic flow control so you do not have to reset, the hardware and installation software is very simple to use.

Second, the performance parameters

1, serial port features: Interface compatible with EIA / TIA RS-232C, RS-485 standard.

2, Electrical Interface: RS-232 terminal DB9 hole side of the interface, RS-485 terminal DB9-pin connector, with

Line column.

 

3, work: asynchronous half-duplex.

4, transmission medium: ordinary line, twisted pair or shielded line.

5, the transfer rate: 300 ~ 115-21BDS.

6, transmission distance: 5 meters (RS-232 end) 1.200 meters (RS-485 end).

7, communication protocol: transparent.

8, the working environment: -10 ℃ to 85 ℃ relative humidity of 5% to 95%.

9, the signal: RS-232: TXD, RXD, RTS, CTS, DTR, DSR, DCD,

CND; RS-485: Date +, Date-, GND.
