[esekh_apc]

Try connect to  APC UPS  RM 750 (SMT750RMI2U) via serial interface and cable that was with device 940-625A. Used real COM1 port where OK work early old my UPS SMART 1000.

I try to use software:

• PowerChute Business 9.2.
• APCUPSD
• PLINK for direct connect to com1

But device not detected. COM Port not answer.

I have information that SMT750 should work with serial port in any case.

When i test to use with USB  connection  PowerChute  Business  9.2 detect ups OK .

I manual described that can work or serial or USB  connection in one time. May be need switch by some procedure ? 

Factory reset not help in my case.

Thanks for SerialTerm.exe. By this apps I detected wrong MB cable connector. They was with other order of pins.
And now I know that new SMART-UPS use SPEED 9600.8.n.1.n,  with old SMART-UPS used speed 2400.8.n.1.n

At image show order of pins.

But now other problem with start Agent.

After many reinstall of program agent 9.2, now not started service of PowerChute Business Edition Agent.

Hello,

What software are you trying to connect to the the UPS over serial comm? If anything other than PowerChute Business Edition it is not supported. If PowerChute Business Edition is failing to discover the UPS over serial comm what version of PowerChute are you installing?
