I purchased a [APC BACK-UPS 800VA 230V] yesterday. This UPS doesn’t come with a data cable for using the PowerChute PE application. Neither does the user manual state anything about this topic nor does the product description in the APC website state something about it. However, I can see a port labelled ‘Data Port’ on the right hand side of the UPS. It is an RJ45 port and I tried inserting one end of an ethernet cable, which fits in perfectly.Can anybody tell me what is the use of this port?
