as UPS "SUA750i" is no longer available, we would like to switch to "*SMT750i*". There is no difference in size, but the RS232 connector is different.
In the old version "SUA750i" has a 9pin D-Sub connector which supports the RS232 signals as well as the status lines " UPS aktiv" and "UPS accu nearly empty".
My question now is: Are these two additional status lines "UPS aktiv" and "UPS accu nearly empty" already part of the RS232 connector ( 10pin RJ45) of "SMT750i.
The provided cable includes only signals for RS232 function.
Can somebody provide me the pinning of this 10pin RJ45 connector of *SMT750i*?
Thank you very much for any information.

yes i know. this can be provided if escalated via tech support as we cannot post it publically. you also could pursue the 940-0128 cable which is RJ-45 (RJ-50) to DB-9.

USB or RS232 interface is no problem.
My request is: are the two status lines "UPS avtive" and "accu nearly empty" which are connected to pin 4 and 5 of the 9pin D-Sub connector from APC S*U*A750i
are also available on 10 pin RJ45 connector of APC S*M*T750i? Therefore, I'd like to know the signal assignment of that connector.

i answered your other post. what software or interface are you using to read these signals? we offer USB or serial on this UPS and software that provides this same information.

The SMT750i utilizes a different language that the SUA model. It is based from MicroLink Language which means that in order for you to do those things that you previously had on our older UPSs (SUA,SU) you will need to install our AP9620 Legacy Communication Card.
Below is the link to the Compatibility of the Legacy Card

you're absolutely right: The only thing, which I need, is a cable or the pin assignment of the RJ-45 connector.
For better understanding, please notice the appendix.
