-All ASI Controllers(TG-1000/​Tiger, ​MS2000 ​and RM2000utilizes ​an RS-232 serial link to connect with any computer ​with an RS-232 ​serial ​port in order to utilize all of the controller’s abilities.+All ASI Controllers (TG-1000/​Tiger, ​MS-2000 ​and RM-2000have an RS-232 serial link.  While the controller can be used in stand-alone mode completely separate from a computer, having a connection so send serial ​commands is required ​to utilize all of the controller’s abilities.
  
-For controllers ​built since approximately 2008, the primary ​physical ​connection is most often a USB Type A to Type B cable. ​ The controller includes a chip that emulates a serial ​com port over the USB connection ​(i.e. the controller will appear to be on COM port).  USB with emulated RS-232 port is the only interface option ​on TG-1000 ​"Tiger" ​controllers, ​but MS2000 ​and RM2000 controllers will usually have a physical ​RS-232 ​serial port as well.  ​In case the operating system ​doesn'​t ​automatically install the drivers, they can be found at http://​www.silabs.com/​products/​mcu/​Pages/​USBtoUARTBridgeVCPDrivers.aspx. ​ As of early 2018 there was a bug affecting the "​Universal"​ version of the SiLabs driver when used with the ASI Console programs (depending on .NET) so use the Windows 7/8/10 version 6.x instead.+MS2000 and RM2000 ​controllers ​normally have a physical ​RS-232 ​serial port (a 9-pin D-sub connector).  ​There is a USB Type A connector on controllers built since ~2008 and on TG-1000/Tiger controllers, ​which is these days more common to use because USB ports are ubiquitous ​and more plentiful. ​ It does not make difference which physical ​connector is used.  For USB connection, the controller includes a chip that emulates a serial ​com port which requires drivers.  ​Sometimes ​the operating system ​will automatically install the drivers ​for this chipbut if not they can be found at http://​www.silabs.com/​products/​mcu/​Pages/​USBtoUARTBridgeVCPDrivers.aspx. ​ As of early 2018 there was a bug affecting the "​Universal"​ version of the SiLabs driver when used with the ASI Console programs (depending on .NET) so use the Windows 7/8/10 version 6.x instead.
