Specifications

NAME: Four RS-485 intelligent data converters
MODEL: UT-2204
DETAIL:       UT-2204 is an environment designed to address the complex requirements of RS-485 systems designed to separate RS-485 bus hub (HUB). It supports transfer rates up to 115.2KBPS, built-in data cache and the microprocessor, power supply using an external switching power supply, safe and reliable, ideal for engineering applications.
      In RS-485 mode, the circuit used to automatically determine the direction of data flow-aware and automatically switch to enable the control circuit, easy to convert RS-485 transceiver to solve the delay problem. RS-485 interface transmission distance greater than 1200 meters, and stable performance. Widely used in video surveillance systems, is a good performance data interface conversion products.
      UT-2204 RS-485HUB provide star RS-485 bus connection. Users can easily improve the RS-485 bus structure, split segments, improve communications reliability. This performance has greatly enhanced the existing RS-485 network reliability, effectively reduces network maintenance time. Reasonable use of UT-2204 RS-485HUB can help you design a unique highly reliable RS-485 systems.
