Product Description

Product enclosure dimensions (excluding terminals): Length 88mm Width 37mm H 59mm.

Installation of industrial passive RS232 to RS485 guide rail.

Self powered, adaptive baud rate, industrial standard design, high-level protection.

 

I. Product Introduction

Our 232 / 485 CONVERTER is a converter of two-way interface between RS232 and RS485, applied between the master controller and point-to-point and remote multi-computer communication network, widely used in industrial automation control system, card, access control system, parking system, self-service banking system, bus charging system, dining hall meal sales system, company staff attendance management system, highway toll station system, etc.

Our 232 / 485 CONVERTER is able to convert the TXD and RXD signals from the RS232 serial port into two-line balanced half-duplex RS485 signals. Without external power supply, the signal pin directly from the RS232 port, hardware and installation use is very simple.

 

II. Performance parameters

1, serial port characteristics: compatible RS232C,RS485 standard of EIA/TIA;

 

2, working mode: asynchronous half-duplex;

 

3, transmission medium: normal wire, twisted pair wire or shielding wire;

 

4, transmission rate: ***-115,200 bps;

 

5, transmission distance: 5m (RS232 end) 1200m (RS485 end);

 

6, communication protocol: Transparency;

 

7, working environment: -20 ℃ to 70 ℃ relative humidity is 5% to 95%;

 

8, signal: RS***----TXD, RXD, GND;

 

RS***----Data +, Data-;


 

III. Wiring mode

1, device GND, RX, TX is connected to GND, TX, RX at RS232 end, namely, device GND is connected to RS232 end GND, device TX is connected to RS232 end RX, and device RX is connected to RS232 end TX.

 

2, devices D + and D-are connected to RS485-end A + and B-respectively.

 

IV. Failure analysis

 

The 1, Data Communication is not successful:

 

A, detects whether the RS232 interface connection is correct;

 

B, detects whether the RS485 interface connection is correct;

 

The C, detects whether the signal level difference of the RS232 interface is less than 5V;

 

2, data loss or confusion:

 

A, detects whether the data rate and format of the two segments of the data communication equipment are consistent;

 

The B, can add a matching resistance of 1 / 4W 120 Ω.
