Necessary tools:
NetLinx Studio 2 (NS2)
USB cable (if downloading via USB)
Network connection information (if downloading via ethernet)

Necessary files:
SW2261-02-KIT  (SW2261-02_NXD500i_v2.86.5.zip)

Procedure:
1) Extract the zip file
 	It should produce four kit files "SW2261-02_NXD500i_v2.3prep.kit", "SW2261-02_NXD500i_v2.4prep.kit",
   	"SW2261-02_NXD500i_v2.4.28.kit" and "SW2261-02_NXD500i_v2.86.5.kit"

   	Note: The file SW2261-02_NXD500i_v2.4.28.kit is not needed for this procedure but is included as a 
	convenience in case a downgrade is desired.


2) If the panel is currently loaded with version v2.4.28 or later then perform the following steps
	(a) Boot the NXD-500i and configure a connection to NS2
	(b) Ensure that the reboot device button is checked on the Send to NetLinx Device firmware transfer page
	(c) Verify that panel is loaded with v2.4.28 or later
	(d) Download SW2261-02_NXD500i_v2.86.5.kit
	(e) After the upgrade is complete and an NI-Controller connection is re-established verify that the panel is at version v2.86.5

3) If the panel is loaded with an earlier version than v.2.4.28 then perform the following steps
	(a) Boot the NXD-500i and configure a connection to NS2
	(b) Ensure that the reboot device button is checked on the Send to NetLinx Device firmware transfer page
	(c) Determine the firmware version of the NXD-500i.  If it is in the 2.2 series (such as 2.2.50) go to
   		step d.  If it is in the 2.3 series (such as 2.3.22) skip to step e
	(d) Begin the upgrade by downloading the "SW2261-02_NXD500i_v2.3prep.kit" to the panel.  It may be
   		necessary to wait up to 5 minutes after the panel reboots for the upgrade process to complete
	(e) After the upgrade is completed and a NI-Controller connection is re-established, download the    
		"SW2261-02_NXD500i_v2.4prep.kit" to the panel
	(f) After the upgrade is completed and a NI-Controller connection is re-established, download the
   		"SW2261-02_NXD500i_v2.86.5.kit" to the panel
	(g) After the upgrade is completed and a NI-Controllerconnection is re-established, verify that the panel
   reports a firmware version of 2.86.5
