Start Here! Homelab Wiki HomelabSales ![]() It therefore could only support simplex (one-way) protocol, as it's missing RX! A null modem cable surely would not work at all! Specifically, the CyberPower UPS cable that they sold to me for their devices has only 5 pins connected: pin 1 (DCD), pin 3 (TX), pin 4 (DTR), pin 7 (RTS), and pin 8 (CTS). I don't know how I mixed that up! I'm going to try to get my earlier post edited by the admin or deleted, as I don't want to be spreading misinformation. Using USB connection, PowerPanel Personal Edition 2.2.0 works with this newer UPS (maybe it might work on serial port too if I had a regular serial cable?), and while there is a lot more information available about the UPS in the program, such as the ability to trigger self-test and see battery percentage, there still is no way in the software to configure the audible alarm!Ĭlick to expand.I re-tested today with better tools, and discovered the CyberPower UPS serial cable is indeed a straight extension cable like the OP originally said and has used successfully. I'd rather it beeped constantly like the older one, given that I prefer not to run software to know quickly that the power went out. I actually just got a slightly newer CP550, this one has both the serial and USB ports and it only beeps once every 10 seconds or so when power goes out. So I figured long ago, who needs on screen notification as well? Yes, once on battery it beeps constantly (until the battery runs out, power comes back on, or you switch it off) and there is no way to configure it to behave otherwise. are you sure it was a extension/straight-through and not a null modem? Maybe the device doesn't even use those crossed lines, it's pretty basic as far as the communication with PC is involved. ![]()
