GC-RT12 - BACnet Integration Device - BACnet Ethernet Router


GC-RT12 is a level consistent with BACnet B-ASC Ethernet router. It is a communication bridge between workstation and field controller. Therefore It has a 100M Bases-TX Ethernet port that can communication with operated workstation and global controller through BACnet Ethernet or BACnet/IP communication protocol. In addition it has two MS/TP ports can connect up to 64 sets DAC or DSC series controller and hundreds of expansion modules to form a BACnet network backbone.

GC-RT12 supports proportional, integral, differential, floating, logic, arithmetic calculation and subroutine functions. GC-RT12 in conformity with international BACnet network communication and fully compatible with any BACnet system. It is absolutely the best product for your building.  


  • In conformity with BACnet MS/TP, BACnet Ethernet ISO-8802-2, BACnet/IP protocol formulated by ASHRAE fully compatible with any BACnet system.
  • 32-bit high performance MCU.
  • An Ethernet communication interface can be either BACnet Ethernet(ISO-8802-2) or the BACnet/IP communication protocol.
  • Two MS/TP RS-485 communication interfaces, communication speed from 9.6 to 76.8 Kbps adjustable, transmission distance 1,200 meters, each MS/TP interface can connect up to 32 DAC or DSC controllers.
  • Each MS/TP port has 2500Vrms optical coupling isolator and TVS ARRAY surge protection that can effectively avoid network abnormality signal influences.
  • On-line edited, downloaded the logic program as well as real-time program debugging function.
  • Operation functions of proportional, integration, differential, floating, logic, mathematic, and subroutine functions. 
  • Possessed 150 analog value (AV) points, 150 binary value (BV) points. The BV points have the priority function.
  • Both BV and AV points have power failure memory. Data will be save in FRAM and keep for more than 10 years.
  • These AV points are doing floating point operation. It provides high accuracy and number size. It makes the ratio multiplication in a program or a display unnecessary.
