Product details
MS-1004 is a specialized RS-485 system designed to solve complex electromagnetic field environments
Designed RS-485 bus division hub (HUB). This product supports transmission speed
The maximum rate is 115.2KBPS. In order to ensure the safety and reliability of data communication, RS-485 is connected
The port adopts optoelectronic isolation technology to prevent lightning surges from entering the converter and equipment
The photoelectric isolator and 600W surge protection circuit installed can provide a 2500V isolation
Off voltage can effectively suppress lightning and ESD, while also being effective
To prevent lightning strikes and common ground interference, the power supply adopts an external switch power supply, which is safe and reliable
Damn, it's 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 the control circuit, easily solving RS-485 transmission and reception conversion
Change the latency issue. The RS-485 interface has a transmission distance greater than 1200 meters and stable performance.
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-1004 RS-485 HUB provides star shaped RS-485 bus connection. Each port
All have short-circuit and open circuit protection. Optoelectronic isolation 2500V, users can easily improve it
RS-485 bus structure divides network segments to improve communication reliability. When struck by lightning or equipment
When a backup fault occurs, the problematic network segment will be isolated to ensure the safety of other network segments
Normal operation. This performance greatly improves the reliability of existing RS-485 networks,
Effectively shortened the maintenance time of the network. Reasonably utilize MS-1004 RS-485
HUB can help you design a unique and highly reliable RS-485 system

The front panel of MS-1004 has a total of seven indicator lights, and the left and right ends are each connected with ten digit wiring
Column. The TXD RXD GND on the left end is the RS-232 signal input terminal, 485+485-
For the RS-485 signal input terminal, GND is the ground. The right end is the 485 signal output port T/
R1+、T/R1-、T/R2+、T/R2-、T/R3+、T/R3-、T/R4+、T/R4-、
GND, GND. Note that the GND of the 485 output terminal cannot be connected to the GND of the input terminal.
The front panel indicator lights of MS-1004 have the following meaningsPWR 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 ports 1-4 send to INPUT ports E1-E4 ports 1-4
The fault warning indicator light, when constantly on, indicates that it is connected to ports 1 to 4
When the RS-485 interface device experiences a short circuit or signal reverse connection, the E1 light and
Port 1 corresponds to port 4, and E4 lights correspond to port 4. Users can issue a warning based on this fault
The indicator light identifies the faulty port and its connected faulty device.
