RS-232 to RS-485 Converter

User Manual

Product introduction

HXSP-2108A converter is the communication converter

which change RS-232 signal to RS-485 signal completely

isolate. It has the strong drive capability which can drive

max to 64 devices on the bus. The communication

distance max up to 1000 meters. It is designed elegantly,

easy to connect wire, convenient to use. It is widely use d

in industrial monitoring, civilian PTZ monitoring, and

industrial control equipment, and other field s

There are two connection methods:

Two HXSP-485 converters connect:

HXSP-485 …………………………………HXSP-485

Data (＋) …………………………………Data (＋)

Data (－) …………………………………Data (－)

GND …………………………………GND

HXSP-485 connect with RS-485 equipment

HXSP-485………………………………… RS-485 equipment

Data (＋)………………………………… …T+/R+ or 485+

Data (－)………………………………… …T-/R- or 485-

Problem analysis：

1. Data communication unsuccessful

A. Check RS-232 interfaces whether to be correct;

B. Check RS-485 interfaces whether to be correct;

C. Check whether RS-232 signal level（TXD、DTR、RTS）lower than＋5V, if that,

it can get through power from 6 th pin of DB9 Male.

2. Data missing or messy code

A. Check whether the baud rate and format of both sides of data communication

equipment are same.

B. If possible, add the matched resistance on the terminal circuit (120 Ω,1/4 w)
