GN RS 485 Interface Module


RS-485 network interface module is a programmable communication module with CPU, which adopts X86 series 80188. User can program as needed, fulfill communication and control with the communication software interface provided by Googol Technology. RS-485 network interface module has a RS-485 and RS-232 user interface, a PC104 standard bus interface connected with motion controller, which can be inserted into Googol motion controller and establish an economical network motion control system. At the same time, Googol Technology provides human-machine control interface module with RS-485 network function and Chinese display module to facilitate establishing network control system.
