THE C2-65 is a USB to serial converter RS422/RS485, designed for industrial application.
C2-65 is powered directly from the USB port of the computer to which it is connected , and has the USB and RS-422/485 sections galvanically isolated between them.
The device is compatible with USB 1.1 and 2.0 and the standard RS422 (full duplex) and RS485 (halph duplex).
In case of halph duplex operation, the time of change over is extremely low (1 bit time) also at the higher baud rates that thanks to the technology of optical isolation particularly fast can reach the speed of 900 kbit / sec.
C2-65 has been realized in a very compact size .The metal housing gives the product a shielding effect that ensures full compliance with CE regulations regarding both the emission and conduction even at RS485/422 line terminated.
User can set using dip switches :
1. line terminations,
2. the type of line (if RS422 or RS485)
3. The operation “loop mode “, with simple commands from PC (Iperterminal programs or equivalent ) you can test the device in field , directly from the PC and then eventually locate the malfunction.
C2 65 is the only device of its kind to have this feature.
The C2-65 is compatible with all windows operating systems.
The internal microprocessor on which it is based is the FDTI, leading in the world of on-chip USB drivers .
With the variant C2-75, you can get 2 RS485 drawn from a single USB interface, each standards-compliant RS485 transmission, with independent driver and terminations.
The use of this converter requires a verification of the specifications of the USB port to which is connected, which must guarantee 500 ma.as max of current delivered.
