General Q&A

What is the difference between Contact Closure UPS and RS232 UPS?

Contact Closure UPS is a UPS which also named relay interface UPS or dry contact UPS. The common UPS DB9 connector types are (ref. Products-RUPS):


RS232 UPS which follows Megatec protocol is an intelligent UPS.



What is the difference between Bundled version & Standard version?

The Bundled versions are in plastic packing, without manual (can opt to add a manual with an additional cost) and they are primarily for UPS manufacturers to bundle the software with their UPS. And most importantly, they are not for resale.


The Standard versions are in box packing, with manuals and they can be sold separately from the UPS (buyer can opt to sell with UPS too). These are supplied to UPS manufacturers, dealers or importers.



What is the difference between RUPS 2000 & UPSilon 2000?

RUPS 2000 is used on contact closure UPS, while UPSilon 2000 is used on RS232 UPS follows our MEGATEC protocol.




RUPS2000 Q&A

When we use the RUPS 2000 on the Windows NT, is there anything we have to setup besides connects the M2501 cable on the COM port?

The M2501 cable is compatible with the specification for UPS connection from Microsoft. Connect the male connection of the cable to the UPS and the female connector to the computer? COM port, setup the UPS settings in the Control Panel and restart the UPS service.



When we close the UPS configuration in the Control Panel, the Windows NT will restart the UPS service, but the messages show that the UPS service cannot start normally.

1. Check if the COM port setting is correct.
2. Enable the Power Failure Signal, select Negative.
3. Enable the Low Battery Signal, select Negative.
4. Enable the Remote UPS Shutdown, select Positive.
Restart the UPS service after finished the configuration



What is the possible cause if the settings are correct but the UPS service cannot start?

Disconnect the M2501 cable from the UPS and restart again. If the service restarts normally, it means the UPS connection has problem. Please check this with the UPS manufacturer if the AC power is normal. If the UPS service cannot be started after UPS
cable disconnect, check if the RS232 port or replace the M2501 cable.



What is the possible cause that the UPS service setting and restart normally, but Windows NT restarted, UPS went abnormal or been switched to the Bypass Mode, which means the power will be turn-off when the AC failure happened.

When the Windows NT started, Windows OS will reset the COM port in the system, which will make the DTR signal active of the COM and send out the Turn-Off signal to the UPS.

For some UPS, this will make the UPS switch to the Bypass Mode and turn-off the power protection function.


Solutions are:

1. inform the UPS manufacturer to modify the UPS communication interface.

2. use the M2601 adapter to solve this problem, the M2601 will send the turn-off signal to the UPS only if the AC is failed.

3. Change the cable M2501 to M2601, the M2601 cable is the combine of the M2501 cable and the M2601 adapter.



What is the reason that the problem happened only in the Windows NT system but not the Novell Netware or the MS-DOS system?

In the Windows NT system, Windows OS will reset the COM port in the system, which will make the DTR signal active of the COM and send out the Turn-Off signal to the UPS. In the Netware or MS_DOS system, the device driver can drive the COM directly and avoid this problem



When the Power failure happened, Windows NT ignores it, but shutdown the system when battery low happened?

When the Battery Low signal enabled, Windows NT will ignore the power failure signal, the system will be turn-off when the battery low happened.



Is it possible to shutdown the Windows NT system when the AC failed for 5 minutes, but not after battery been exhausted.

Yes, please disable the battery low detection function and setup the time in the Expected battery life.



I already setup the Expected Battery Lift 10 minutes, but the Windows NT shut down when power failure?

In the Windows NT UPS configuration, there is a parameter named Battery recharge time per minute of run time, the default value is 100 minutes, which means the NT runs 100 minutes to make UPS supply system power for 1 minute. When the system power
failure, the Windows NT thinks the power is not enough for running, so the system been shutdown immediately. Change the parameter into 2 minutes if you want to test this function.



Could we set the schedule turn-on turn-off time in the Windows NT UPS service?

No, There is no this function in the Windows NT UPS service. Please select the RUPS II software and an Advanced Intelligent UPS for the schedule on/off function.



RUPS 2000 batch file to shutdown server.

Users could make their own shutdown batch file and save it in the'SYS:/SYSTEM' with the filename 'RUPSDOWN.NCF'.



Mistakenly installed RUPS 2000 on WindowsNT

When using Windows NT with RUPS 2000, there's no need to install RUPS 2000 software, only the cable.


If WindowsNT already has it's own UPS monitoring utility and RUPS 2000 has been mistakenly installed, please remove using the following steps:


1. Go to MS-DOS box and type Set to look for the Windows NT directory

2. In Windows NT directory, still in MS-DOS, type Regedit, then click the following in order:







     LOAD, delete RUPS2000.exe

3. Then reboot & reinstall.

"HP-UX"  I can not reboot system normally after I installed RUPS 2000 for UNIX on my HP system and followed with error message "getty a tty fail".  This message show up repeatedly and I can not log into the system.

1. In order to modify, try on of the following methods to get into the system

    a. Press "Break" button.  You can get into the system if the process if interrupted.

    b. Get into the system with Telnet.  Kill Daemon process of RUPS 2000.

    c. Get into the system with management mode to modify.


2. Modify the file /etc/inittab.  Insert # in the top of the line rups (or rupsii) and then save file.


3. Modify the file Startup.

    a. In the system HP-UX 10.xx: Find the file S860rups in installed directory /tmp/rups (or /tmp/rups2) Copy S860rups to /etc/rc2.d

    b. In the system HP-UX 9.xx

        i. RUPS for UNIX: Insert one line "etc/rups/rupsd" before the line "}" of the process section "localrc( )"

           localrc( )





        ii. RUPS for UNIX or UPSilon for UNIX: Insert one line etc/rups/rupsd "(twelve spaces)" before the line "}" of the process section "localrc( )"

In UNIX system, the system server follows the shutdown process when the system still runs backup files

Insert the process below to the UNIX start-up or manually execute it.  In that way, the system will finish the backup program before the server shuts down.


at -f file -t mmddhhmm (month/date/hour/minute, **Note: do not input the "mmdd" for executing it everyday)



In RUPS 2000, some functions (e.g. Configuration, History Information, Shutdown Information) will not show up normally.

This problem caused by the older version file "bwcc.dll" located in windows\system. The resolution is copy the new version bwcc.dll file to windows\system, and the new version one could be found in the RUPS installed directory.  Before doing the
copy, rename the bwcc.dll in windows\system to bwcc.bak, this is to avoid the utilization of other application, just in case.



I installed RUPS 2000 at my client site and have problem with loading the service.

I install the software under administrator privilege and its work fine, then I tried to log on with my client user which is Power User and get the error service fail to load.  I change the user privilege to Administrator and its work fine.

I want to set back the user to power user privilege!  What is the problem?

Please make sure logon in administrator account if you are using Windows 2000 operating system or above.



After RUPS Installation, when I want to start RUPS Manager, there is a message, "RUPS Service is stopped" Start the service now? - YES or NO?  If I click YES, there is a message, "RUPS service failed."

Please upgrade the software to the latest version and make sure logon in administrator account if you are using windows 2000 operation system or above.




UPSilon 2000 Q&A

Could we use the UPS service from the Windows NT and the UPSilon 2000 in a system?

No, only one of them could be loaded into the system.



Do we have to login into the Windows NT to execute the UPSilon 2000?

"I have been trying to set a scheduled setting for turning on my computer at a scheduled time for my weekly virus scan. In trying to set a time for turning on, say TUESDAY at 19:00 hr. and turning off at 19:30 hr. The UPS will not turn on at the scheduled time. But if I turn on the UPS myself at 19:15 hr. the UPS will turn off the computer at the scheduled time of 19:30 hr. I have tried some special settings with the same results."

After setting whatever schedule, it is a must do shutdown from UPSilon 2000 first.  Goto "Control" then click "Shutdown"



"UPSilon 2000 does not try to save any program that is open, I've simulated a power outage, while Word97 is in used. The UPSilon 2000 shuts down the computer orderly, but it ends in the Windows shutting down screen "Please Wait For Win95 To Shut Down", and then it shuts off the computer without waiting for the next screen, "It is Safe To Shut Off Your Computer"

The problem lies in the time set for shutdown.  Different Operating System have different time range for shutdown. In this case, the shutdown time set is too short , that is why the PC was shut off before the safe screen displays.  Try to prolong the shutdown time.



UPSilon 2000 cannot work under Novell Netware 4.11 but it works perfectly with other operating system including Novell Netware 3.1
