UPS Lite Manager – control utility for UPS

A program for managing a UPS that supports the Megatec protocols (many UPS Ippon, Mustek, Sven, etc. use it) and MegaUPS (some UPS DEXP use it).

Main features UPS LM

Key features and differences from similar software:
• Consumes little RAM and minimal CPU time;
• Does not require installation or drivers;
• The situation with pulling out the USB/COM cable from the UPS is thought out and processed;
• It is possible to control several UPSs connected to one computer at once;
• Event processing: no voltage, charge reserve below specified, battery low, power restored, UPS lost, UPS faulty;
• Notifications by email (built-in SMTP client), VKontakte, Telegram;
• Launch files based on events, shutdown Windows;
• Terminal console for a USB/COM interface for manual control of the UPS – you can independently enter various engineering commands;
• From the commandline you can run some UPS commands (testing, sound, unloading, etc., more details in the help on ups_lm.exe /?)

This is a beta version – its stability is not guaranteed!

System requirements for the computer and UPS

System requirements – any version from WindowsXP SP3 to Windows11, 32 or 64 bit.
Similar server versions of Windows are also supported.

Connecting a UPS via USB-HID, RS232 (or USB-COM).
For USB-HID is expected to work with a UPS with the following PNP codes (equipment ID):
HID\VID_06DA&PID_0003
HID\VID_0665&PID_5161
HID\VID_05B8&PID_0000
HID\VID_0F03&PID_0001
HID\VID_0001&PID_0000
In addition, in the settings you can manually set any VID/PID codes.
As for support for other UPSs, please contact us by email, if there are no significant differences, they will probably be added…
The author has Ippon Smart Winner (old generation), the program is being tested on it, all other models may have some problems – they will be corrected as bug reports are received.
Ippon Smart Winner of the new generation (which has a display) is not supported.
The program works with any UPS that is defined as a standard USB-HID device (or COM/RS232) and responds to the Q1, QS or Q4 command, or similarly responds to index 0x03 requests.

Installing UPS LM

UPS_LM does not require installation and does not store settings in the registry (except for autorun). All settings are stored in the UPS_LM.ini file, which is created in the same place where UPS_LM.exe is located.
A file UPS_LM.db is also created in the folder with the program – statistics of minimum and maximum levels are kept there.
The program does not require administrative rights, but the folder with the program must be writable (therefore, this should not be placed in Program Files – in modern Windows, writing there is blocked via UAC, even for an administrator account).
Parallel work with several UPSs is possible – to do this, you just need to place several UPS_LM.exe in different folders.

Setting up alerts via the Internet

Since UPS_LM supports compatibility even with old Windows XP and Windows 7, to connect to modern servers (using TLS 1.2/1.3) we had to use a third-party component – OpenSSL. Even when using UPS LM on Windows 10/11 – currently using OpenSSL. If you are going to use the functionality of notifications by email/VKontakte/Telegram, then you need to install OpenSSL v3.3 (or newer) – you need the libcrypto-3.dll and libssl-3.dll files in the folder with UPS_LM or available in the system.
OpenSSL v.3.3 has at least two public builds:
• Variant 1: Win32 OpenSSL v3.3 Installer (slproweb.com) – require Visual C++ 2015-2022 Redistributable (microsoft.com) for WinVista+, for WinXP/Win2003 requires an older version of Microsoft Visual C++ 2015-2019 Redistributable 14.28.29213 (google);
• Variant 2: OpenSSL Binary Distributions for Windows (firedaemon.com) – without external dependencies (only UCRT), WinVista+.

Using the Command Line

There must be UPS_LM.exe running earlier, commands are sent for execution to the previously running process through a Pipe.
Command line control may be disabled in UPS LM settings.
Please note that communication with the UPS occurs through a queue, the command will actually be performed not immediately, but after a few seconds.
If there is no previously started UPS_LM, then it will be started and will remain working.
UPS Direct Commands:
/T – start a 10 second battery test (T command on UPS);
/TL – launch a battery test until it is completely discharged (TL command on UPS);
/CT – cancel battery test (CT command on UPS);
/Beep_On – turn on sound (check status and Q command on UPS);
/Beep_Off – turn off sound (check status and Q command on UPS);
/C – cancel shutdown commands (turn on the UPS immediately);
/Snn – UPS shutdown, nn – time in minutes (01-99) after which the UPS turns off;
/SnnRnnnn – turn the UPS off and on again, nn – time in minutes (01-99) after which the UPS turns off, nnnn – time in minutes (0001-9999) after which the UPS will turn on;
Many UPSs do not support some of these commands.
Please make sure your UPS supports these commands before use.
/exit – closes a running copy of UPS_LM.
/MsgTest – checking the command line with a running copy of UPS_LM.
You cannot specify multiple commands at once.

Reference information on the UPS protocols used

UPS LM version 2.0 supports 3 types of protocols:
• Megatec/Ippon/Voltronic-V – classic protocol, UPS-HID, usually Q1 text request and text response.
• MegaUSB/DEXP/UPSmart – responses are like in Megatec, text, but requests are not text, but index code via GetIndexedString.
• Voltronic-P/T – requests in text as in Megatec, but the answer is in binary form.
More detailed descriptions are given on the Russian version of this site, or Network UPS Tools.
