can't establish hyperterminal communication with apc smart ups 5000 rt

[Anonymous user]

Hello,

I have brand new APC Smart UPS 5000 RT and I am trying to connect to it with hyperterminal. I have used settings 2400 bps, N, 8, 1, no flow control. But after pressing enter I dont get any response from ups.
I tested on my windows notebook and another computer with linux minicom as well without success.
What could be the problem ?
There is network interface on the UPS as well, can I use it to connect to UPS ? What is the default IP address ?

Thank you !

can you please confirm the exact model number on the UPS?

SURT5000XLT/SURT5000XLI uses a DB-9 connector on the back of it for communication and you need the cable part number of 940-0024 or 940-1524 to establish the connection. it is a DB-9 to DB-9 cable. the port settings on that are those that you tried: 2400 bps, N, 8, 1, no flow control. it wont work though if you arent using the APC cable I mentioned.

if the unit is a SURTD5000XLT /SURTD5000XLI (notice the D in the part number), then the communication port you need to be plugging into is RJ-45 and I believe it is labeled "communication" or "serial." It is NOT the one located on the actual network management card (AP9617, AP9618, or AP9619). the cable required for this is a 940-1525A cable and is RJ-45 to DB9. The port settings for this unit are different and it uses a baud rate of 9600. the rest of the settings are the same: 9600 bps, N, 8, 1, no flow control.

you will want to make sure the status lights on the network management card are lit up too for status and link.

by default, the network management cards are set up for DHCP/BOOTP but also require option 43 (which is a vendor cookie) to be set up on the DHCP/BOOTP server before it will accept the address. this is an option you can disable once you gain access to the card if you'd like.

hope that helps!

My model is SURTD5000XL so I changed the speed to 9600 and the communication is working now.
I got user name prompt.
Thank you !
