Serial Communication with APC UPS 750

This was originally posted on APC forums on 8/2/2016


Hello,

I am trying to communicate with APC SMART UPS 750 using serial port to get the UPS status. But I am not getting any response from the UPS. Is there any C Code that does this work? 

Thank you in advance.

I'm looking for the same thing. If you got the C code, can you please provide me that code so that i can explore and implement it in my application.

Hi,

If the unit is model SUA750 then you can follow the instructions in Knowledge Base document FA276164 to run UPSLInk commands via Hyperterminal.  

If the model is SMT750 or SMX750 then you cannot access the UPS using the serial port without installing PowerChute.

I have installed PowerChute, but is it not possible to interact with ups via hyperterminal using C program?

I want to develop some code that reads the UPS status using rs232 serial port based on my command to the ups. Can you help me out in this regard?

Thank you for the reply.

Hi,

I apologize I was not clearer with my first post. You can us PowerChute to configure the UPS (set thresholds) but it is not possible to program the UPS through PowerChute. With a SMT or SMX750 we do not offer a way to program the units directly.

One option you do have is to install a conversion card (part number AP9620) that converts the unit to mimic a SUA750. Then you can use the UPSLink language discussed in the Kbase I referenced earlier to program the UPS. When installing the AP9620 the unit will then mimic a SUA750 so some features of the SMT or SMX750 will no longer be available. As an example those unit have switchable outlets and that feature will not be available once the AP9620 has been installed since UPSLink language does not support switchable outlets.

 Another option is SNMP. You can purchase a network management card (part numbers AP9630 or AP9631) and once the UPS is configured and on the network use SNMP to get and set.

Some of the SmartUPS support Modbus. See:
