UPDATING THE FIRMWARE
The N4865A's fi rmware can be updated in the fi eld without returning the unit
to the factory.
1. Connect the N4865A to a Windows PC as described in paragraph 2.5.1.
Connect the supplied USB power cable to the N4865A and to one of the
computer's powered USB ports. Do not connect the N4865A to a port on
the keyboard as they only have enough power for a mouse.
2. Locate the latest ICS_N4865A_Update fi le on ICS Electronics website at
http://www.icselect.com. Highlight the Download tab and select 'VXI-11
Support' to get to the correct page. Download the .zip fi le to an temporary
directory and unzip the fi le.
3. Disconnect the PC from your company network and change its Local Area
Network setting to the N4865A's AutoIP range as described in paragraph
2.5.1-3.
4. Run the N4865A Update Utility. If it will not run, download the Visual
Basic 6 runtime package from ICS's website or from the Support CD
supplied with the N4865A.
5. Turn the N4865A on. It will take about 25 seconds before the RDY LED
starts blinking and the N4865A is ready to communicate with the PC.
6. Enter the N4865A's default IP address, 169.254.48.65, in the IP Address
window of the Update Program, highlight it and link to it. If you are un-
able to link to the N4865A reset its LAN settings as described in Section
5.5. Retry the linking process when the RDY LED starts blinking.
7. Press the Prgm Flash button to start the update process. The three yellow
LEDs (TALK, LSTN and SRQ) will blink while the new program is be-
ing downloaded. Follow the directions on the screen and re-link to the
N4865A as required to complete the update process.
CAUTION
Do not exit the Update Program until told to do so. It will
ask you to re- link to the unit twice to fi nish the update.
8. After exiting the Update Program, connect the PC back to the company
network and restore the Local Area Network settings to their original
values.
