Product details
MS-1002 is a RS-485 system designed to meet the requirements of complex electromagnetic field environments
And the designed RS-485 bus splitting hub (HUB). This product supports the highest transmission rate
Up to 115.2Kbps, RS-485 interface is used to ensure the safety and reliability of data communication
The end adopts optoelectronic isolation technology to prevent lightning surges from entering the converter and equipment. The built-in
Optoelectronic isolator and 600W surge protection circuit, capable of providing 2500V isolation power
Pressure can effectively suppress lightning and ESD,
At the same time, it can effectively prevent lightning strikes and common ground interference, and the power supply adopts an external switch power supply
Electricity, safe and reliable, very suitable for outdoor engineering applications.
In RS-485 working mode, the discrimination circuit used can automatically sense the direction of the data stream
To enable automatic switching of control circuits, easily solving RS-485 transceiver conversion
Delay issue. RS-485 interface transmission distance greater than 1200 meters, stable performance
Ding. Widely used in highway toll systems, road monitoring systems, and power collection systems
Zhong is a high-performance and cost-effective data interface conversion product.
MS-1002 RS-485 HUB provides star shaped RS-485 bus connection. All ports are
It has short-circuit and open circuit protection. Optoelectronic isolation 2500V, users can easily improve RS-
The 485 bus structure divides network segments to improve communication reliability. When lightning strikes or
When a device malfunction occurs, the problematic network segment will be isolated to ensure the safety of other networks
Normal operation of the segment. This performance greatly improves the reliability of existing RS-485 networks
Sex effectively shortens the maintenance time of the network. Reasonably utilize MS-1002 RS-485
HUB can help you design a unique and highly reliable RS-485 system

The front panel of MS-1002 has a total of five indicator lights, and the left and right ends are each connected with ten digit wiring
Column. The TXD RXD GND1 on the left end is an RS-232 signal input terminal, 485+485-
For the RS-485 signal input terminal, GND1 is grounded. The right end is a 485 signal output port
N/C、N/C、N/C、N/C、T/R1+、T/R1-、T/R2+、T/R2-、
GND2, GND2, please note that GND2 at the 485 output cannot match GND1 at the input
connected
The front panel indicator lights of MS-1002 have the following meanings:
PWR power indicator, normally red
TXD data transmission indicator, normally flashing green, indicating that the data is from INPUT
Send to OUTPUT ports 1 to 4
RXD data reception indicator, normally flashing yellow, indicating data from OUTPUT
Send from port 1 to port 4 to INPUT port
E1-E2 port 1-port 2 fault warning indicator light. When it is constantly on, it indicates that it corresponds to port 1-port 2
When the RS-485 interface device connected has a short circuit or signal reverse connection, the E1 light and
Corresponding to port 1, E2 light corresponds to port 2, and users can judge based on the fault warning indicator light
Disconnect the faulty port and its connected faulty equipment
Electrical interface and its definition
