Tripp Lite MODBUS Management Accessory Card for UPS Remote Monitoring and Control, RS-422/485 & RS-232 Communication Ports, SmartOnline UPS Compatible, 2-Year Warranty (MODBUSCARD)

After running multiple APC PDUs for decades I was getting tired of the slow web interface so I thought I'd give Tripp Lite a try to see if their interface was better. It seemed like the worst-case scenario was that this was just a sidegrade rather than an upgrade. Turns out, it was much, much worse. The networking card died after just a few years and Tripp Lite wouldn't stand by it, instead insisting that I spend $400 plus labor to replace it myself.

This item works as advertised. I replaced one of the older versions of the management cards with this one because it was getting increasingly difficult to get the java applet in the older version to work with newer browsers. This one works fine in every browser I tried, including the ones that come with IOS (iPhone and iPad).The interface itself is pretty basic and plain, but it does adequately communicate the information you need and allows you to configure the UPS, which is really all that's required.

The unit now works but there tech support folks need help unit took 3 days to get it working as the software gives no explanation of what it wrong. after 1 day they offered to take it back and I said no what good is sending it back just get it working. . . 2 days later they did it was a setting issue there was only 1 tech support person worth it the rest only read and spit back the manual well i did that.

This is a great card at a great price. We declined to purchase the earlier version because I didn't want to manage another java applet device. But this card is all HTML5. It installs while the UPS is powered on, and this hot-swappable feature is very convenient. Now I can monitor and control remotely without going onsite.Interestingly it seems to be running Ubuntu 16.04. I intend to do a firmware upgrade, and perhaps this will move it to Ubuntu 18.04.

Product came in on time and as described.

Solid product. Hard to navigate the user interface.

Worked great. Installed with no issues.

good

Mine stops communicating with the UPS every day. Contacted Tripp Lite support and they recommended me to configure a daily automatic reboot of the card... Updated the firmware to the latest version, without any improvement. Power goes out, but we don't receive any notification and our system doesn't shut down.After almost one year without any update, the latest firmware changelog announced only 5 fixes but 95 known issues... Is there any developer working for Tripp Lite?Their PowerAlert Network Shutdown Agent supports Fedora 8, a distribution released in 2007 and OpenSuse 11, released in 2009...
