README for iSerial Set Tool 
	Software utility for certain DNP Photo printers 

About USB iSerial
DNP has added iSerial USB functionality to newer versions of the printer firmware for current printer models.  This function will allow the computer OS to more easily identify and discriminate the DNP printers that are connected via USB.  This improves connectivity. 

Printer models supported by the iSerial Tool:
The iSerial Set Tool is available for DS620 and RX1HS. It is effective for models DS620 with firmware v1.21 and above as well as RX1HS with firmware v2.04 or greater.  

The iSerial tool is not required for DS820 and newer versions of the DS620 and RX1HS printer produced after 2016 as these models are set to have iSerial enabled at the factory. 
Note: The tool is not available for DS40, DS80 nor DS80DX.  

The iSerial Tool can be run to see and or change the current state of the setting.  Printers with updated firmware can use this software tool to view the current state, enable, or disable the iSerial functionality.  

This function when enabled will improve the way the PC operates under certain conditions, most notably these are: 
	For the Mac OS10.9.4 and above, it can now support multiple DNP printers (when iSerial enabled on all DNP printers connected to the Mac simultaneously). 
       For Windows, the OS will automatically reuse the existing Driver Icon. This will avoid the OS creating the Printer Copy 1, Printer Copy 2; whenever the printer is connected to a different USB port.  
Use Tip for Windows 7 / 8 / 8.1 /10 users: Always install DNP printer driver to the computer BEFORE connecting the printer to computer. Please refer “Printer Driver Instruction” in attached CD with printer for detail
