Hi BobF,

Regarding your questions:

My company is using a handful of Devicemaser 32 port ethernet gateways. I was using a web browser and the device IP to log in to the Divicemaster and I was getting some different results from some of them.

A few prompted me with a username and password and when I loggedin, it showed it was running SocketServer 11.11. On a few others, it would not prompt for a password and it showed it was running NS-Link 6.12.

SocketServer indicates that the driver is not communicating to the DeviceMaster. Usually, this happens when using "Socket Mode" to communicate (IP Address and socket port number). Or, the driver may not be configured to work with that particular DeviceMaster.

I need to have all my devices the same and I really need to ensure they are all password protected. Because of the fact that one shows it running SocketServer and the other NS-Link, I did not want to blindly go and try to update anything in fear of locking it up. I looked through the Firmware revision history for SocketServer but I could not see if there was a time when the Software/Firmware name changed or why exactly I see two different GUI's when I connect to these Devicemasters via a web browser.

See above comment:

1. Do I need to update the device to a newer version of SocketServer to get the password logon feature I want, or is there a way to have this function with the NS-Link 6.12 currently running? I do not like how I can configure ports and other options without any security at all.

One way to set the password that is consistent across most firmware version is via Telnet. See this article for details:
http://downloads.comtrol.com/contribs/devicemaster/help_file s/password_protect_the_devicemaster_web_page_&_telnet_se ssions.pdf

Another way to set a password is through the web page for the DeviceMaster. For firmware versions 11.x and above do the following:
1. Open the web page of the DeviceMaster.
2. Go to the Network Tab -> Password
3. Leave the Old Password blank if you don't have one previously set. Enter the new password for the DeviceMaster in the "New Password" field and "Confirm New Password" field.
4. Click on the "Save" button.
5. To test, click on the home tab. Enter 'admin' for "Username" and your new password.
6. Please note that some special characters will be a problem with older versions of the firmware (pre 11.x)


2. Will updating the firmware give the more feature-rich GUI of what I see in SocketServer 11.11 that NS-Link 6.12 lacks?

Update Bootload as well as SocketServer. This can be found here:
http://downloads.comtrol.com/html/DM_PRO_RTS_SERIALHUB_firmw are.htm

3. Is it possible to update this firmware remotely over a telnet session, or will I need to do this in person directly connected to the device? I have these devices at several remote locations

Yes to both. Please see above comments.

I hope I answered your questions. Please let me know if anything else comes to mind.
If a password doesn't work and needs to be removed, please follow the following steps.
Note on the removing password. This will be done in "Console Mode". Ensure the bootloader timeout is
set to a minimum of 30 seconds to allow access to the "Redboot prompt" (bootloader mode).
