Connect to the UPS/device serial port using the correct APC configuration cable. Part numbers are below for common devices. Please refer to the user's manual if you are not sure or your device is not listed.!WARNING! - Connecting a non-APC serial cable to your device can cause unwanted, erratic device behavior. I have an APC UPS 620 and a Windows Server 2012 R2 (non virtual) server. The server and the UPS are connected with genuine APC serial signaling cable. Without installing any software the APC is not.
Is this the NIC card you have installed in your UPS? Game maker studio 2 free. download full.
If so, have you tried using the 'Network Management Device IP Configuration Wizard' to configure it? If you don't have that application, you can download it from here:
Apc Ups Network Setup
Rs232 Serial Connection
Connect your UPS to the same network as the computer you are using to configure it. You can install the configuration wizard and follow the step-by-step instructions that you can find on that same page. I haven't done it in a while but from what I remeber it is very straight forward with that software.
