TD-1204 4-Port RS-485 Hub
4-Port RS-485 Hub
  
 
 
Model: TD-1204
Name: 4-Port RS-485 Hub

 

Description
TD-1204 4-Port RS-485 Hub is a professional design for star-shaped wire layout in complex electromagnetic environment, RS-485 bus, large-scale systems. The RS-485 bi-directional transparent hub transmission, can divide one-way RS-232 bus or RS-485 bus into 4-way RS-485 bus, or put 4-way RS-485 signals all together to one-way RS-232 bus or RS-485 bus. And each port has optical isolation, short circuit, open circuit protection. In the system failure time, the built-in controller can cut off a timely faulty port, to ensure that every port of RS-485 Hub can work independently. every port can connect up to 32 nodes, extend the 1200 meters RS-485 signal. it is good choice to change the simple structure of RS-485 bus.

 

Feature
  • Private input RS-232 and RS-485 2 port, 4 output RS-485 port.
  • Baud rate 300~115200bps auto adaptation, eliminating the trouble of manually set the baud rate.
  • Each RS-485 port has lightning protection and surge protection funcation.
  • Each RS-485 port work independently.
  • Support two kinds of external power supply.
  • More than 5 TD-1204 can be cascaded.
  • Each port can be accessed by 32 standard RS-485 devices(nodes).
  • Support zero-delay auto-conversion transmit and receive.
  • Unique auto-detection circuit.
  • Supports hot-swap function, plug and play.
  • Able to adapt to the user of any application software.
  • can be used as 4 units RS-232 to RS-485 converters.
