S2USB485 Interface

 

Overview

The S2USB485 is a USB to full-duplex RS-232 and half-duplex RS-485 serial converter integrated into a single device.  In essence the S2USB485 is a single USB serial port that has two electrical interfaces available to it (RS-232 and RS-485).  Either interface can be used without the need to set jumpers or change dip switch settings


The S2USB485 can be used as a replacement to the Johnson Controls MM-CVT101 (RS-232 to N2 Bus) / CVTPro100 converter for those computers or laptops that have a USB interface.  In addition to direct support for Johnson Controls software (Metasys, HVAC Pro, etc), the S2USB485 provides the following improved features and functionality:

  • USB interface and so is supported by the latest laptops and operating systems 
  • Does not require an external power supply.  The device is entirely USB interface powered
  • Incorporates both a RS-232C and N2 (RS-485) bus interface so that multiple converters are not necessary.
  • N2 Bus communication is supported under Windows 2000 and Windows XP directly. 
  • Transmit and Receive Indicators
  • N2 Bus flow control internally controlled (i.e. no jumpers or resistors to add/modify)
  • N2 Bus has end of line termination (EOL) enabled or disabled by an internal slide switch
  • Designed and Manufactured in Canada using Industrial grade components 
  • Note: ZoneBus support via the JCI CVTPro100 is not available at this time.
  • ROHS Compliant 
  • New Version (July 2008) now has enhanced overvoltage protection and internal auto reset-able thermal fuses in the event of high voltages present on the RS485 / N2 bus
  • New Version (July 2008) includes enhanced mechanical rigidity of the RS485/N2 bus connector 
  • New Version (July 2008) includes OBD (On-Board Diagnostics) of the RS485/N2 Bus.  OBD allows our S2N2Scan software to electrically  analyze (voltage measuring) the RS485/N2 bus and indicate electrical issues to the user.
  • As of July 2008, the anchored cable version of the S2USB485 (part number S2USB485-JC-C) has been reluctantly discontinued do to the quality issues with our anchored cable manufacturer.  Only the S2USB485-JC-B is now offered with or without the required USB cable (a Type A to Type B).  
  • New Version (July 2008) Pricing has been maintained for this enchanced S2USB485  version.  The included cable version is priced the same as the old anchored cable version 
  • Vista Tested and Compatible 
  • Tested and compatible with JCI's HVACPro and JCI's FX CommPro
  • Windows 7 Drivers will be available on 8/1/2010 at which time we will also be releasing a specific Windows 7 installation document, as Microsoft has changed its Driver installation procedure somewhat.
