Well, it may be proprietary (in the sense of it being a non standard pinout), but you can find pinout diagrams if you know what you are looking for, and if you have a few inexpensive tools, you can also make one. | NOTE: Solder a wire to the metal shell for use as a FRAME-GND |Īnd instead of using a PC with a serial port, I would advise simply getting one of the PL2303-based USB-to-serial adapter cables - they work well for managing serial console stuff with nearly every OS released within the last 10 years. | automatic or PNP cable identification by UPS software.

OTOH, getting this APC cable would also mean I would have to find an antiquated computer that also has a serial port.

However, I have here in hand a Cisco YC Cable that looks like it could work, but I am having hard time trying to find the wire configuration to see if they would match up.

Because we inhereted the UPS unit, this smart-signalling cable is nowhere to be found. I don't have any way of telling if the card is just wnt bad, or if I really have to attempt the serial as these instructions. The only thing that seperates me from the UPS unit is 48p switch, so there shouldn't be any network filtering within the same subnet.

Ran WireShark while attempting previous steps to see if the NIC's MAC or IP appeared anywhere for ARP requests.

Hit the reset button, and the reattempted the previous step.

I did manual arp entry to reach out to as per these instructions.

Ever since, any attempt trying to make contact with the NIC fails.

All was good.įor whatever reason, when we reboot our machine that we had configured for auto-shutdown with our UPS unit, the NIC on the UPS seemingly just dropped it's IP configuration (still trying to figure that one out). First select the tuner, and then the channel lineup for that tuner is shown. Channels are shown separately for each tuner: DTV, TV, Cable DTV, or Cable TV. Long story short, I was able to configure network adapter using telnet. Press the SMART button on the remote control and select Settings > CHANNEL,on the TV menu. The UPS unit uses an AP9606 network card, but also has what looks to be a serial port for terminal use (putty is awesome). We have a UPS unit for which we recently configured to work on our network. First, not sure if this question belongs here or SU, so please advice accordingly before wildly down-voting or blasting me.
