I just purchased 3 APC BACK-UPS ES's and I noticed they all have RJ45 serial connections for the data port to connect to a PC to use PowerChute software...well my question is...I can't find any to purchase one...nor can i find information on how to make one which id much rather do because it would probably be 10x cheaper.  If anyone could give me info on how to make a cable it would be much appreciated...I assume its a simple serial interface and all i would have to do is find the pinout of a RJ45 serial cable to DB9 serial to connect to my PC.  Thanks in advance!

I actually found that site about 10mins ago and bookmarked it for future reference...but i found a DB9 to RJ45 adapter to plug into my PC then i could run a cat5 cable to the UPS...do you think that would work?

Should be a serial cable there. I have a 700XL sitting next to me less than a year old came with cable only has a com port. Is this what you mean by RJ45 ? Ethernet.

I think it will work, but why ? :)
It'll only need to send kB of data not MB :) and it doesn't matter whether you change serial to rj45 because at the end the data transfer capacity of serial port is the limitation.

Matt are you sure. I have never known UPSes to come with only ethernet RJ45. There is a plug on back for extra battery packs that looks similar to ethernet. Do you have a model #

Ok I see those are the small ones. Are you sure the RJ45 connector is for Power Chute it is usually for surge protection of the ethernet connection coming in your Home/business. Only ones I know that work with Power Chute Have com Port connectors I could be wrong mabye they changed it but you might want to double check.

My last 3 APC UPS's have come with USB to RJ45 connectors.
I have a 350 ES that I just looked at and yes the data port is RJ45 and I have plenty of USB ports and they work great.
Yours may have come with the RJ45 to USB.

The adapter you are taking about should work very nicely, but i haven't tested it.
I use them to connect to my routers.

What APC UPS model is it. If you give that info it might be easier to give the correct solution.

I don't think it's a cat5 connection - my APC units have a serial-to-serial connection, so I would guess it's more like a serial cable with an RJ-45 on the end.

According to the user manual:

(6)Connect USB Cable and Install Software (optional)
Note: The Back-UPS software CD-ROM provides
data reporting and unattended shutdown of the
computer connected to the device. The User’s
Guide contains additional information about the
Back-UPS software. The User’s Guide is
contained in the main folder contained in the CDROM.
Attention: USB Hubs
The Back-UPS should be plugged into the USB
port of the computer, not into a USB hub.
The computer must be powered On before
connecting the USB cable. Connect the USB cable
end (USB symbol facing down) to the USB data
port located on the side of the Back-UPS. Connect
the other end of the USB cable to the USB port on
the rear panel of the computer.
Windows 98® and Windows Me® Users
The APC Power Management Extensions
software has been designed specifically to work
with Windows 98 build number 4.10.1998,
Windows 98 SE (Second Edition) 4.10.2222A,
and Windows Me (Millennium Edition).
To ascertain the build number, go to the Control
Panel, open the System dialog and view the
System information under the General tab of the
dialog. To install the software, perform the
following steps:
1. Please skip to step 4 if running Windows Me.
For Windows 98, after connecting the USB
cable, the “Add New Hardware Wizard” dialog
box is displayed. Insert a Windows 98
operating system CD into the computer CDROM
drive before proceeding.
2. Follow the installation instructions on the
computer screen.
During installation, Windows will need to
search for new drivers. When prompted, make
sure the CD-ROM drive box is checked.
3. After installation of the drivers is complete, a
“Windows 98 CD-ROM” dialog box may
appear. If this happens, just close the box.
4. Insert the APC Installation CD-ROM into the
computer’s drive. The software user
documentation is a file on the main folder of
the CD. The filename is Users Guide.pdf.
5. Follow the installation instructions on the
computer screen.
If the software does not automatically install,
the Windows autorun feature may have been
disabled. In this case: Choose “Start” in the
taskbar and then the “Run” option. Type the
following: <CD-ROM drive letter>:\setup.exe.
Click “OK”.
6. After the installation is complete, the APC plug
icon will appear in the taskbar (near the clock).
To view the Power Management user interface,
double-click on the APC plug taskbar icon or,
alternatively, choose: Start > Settings >
Control Panel > Power Management.
Note: Windows 98 and Windows Me categorize a
UPS as an HID (Human Interface Device). The
Back-UPS is listed in: Control Panel > System >
Device Manager > HID category > HID
Compliant Device.
Windows 2000® Users
The CD-ROM included with this package
contains a “wizard” that optimizes a computer
system’s power settings for operation with the
Back-UPS. It does this by changing various
settings in Power Options Properties in the
Control Panel. APC strongly advises that the
computer system be reconfigured by running this
wizard.
1. Insert the APC Power Management CD-ROM
into the computer’s drive.
2. Choose “Start” and then the “Run” option.
Type: <CD-ROM drive letter>:\setup.exe.
Click “OK” and follow the instructions.

That is the 230v model. There is a 120v but that can't be yours because it uses the serial port on the back of the UPS not a RJ45 or a USB

I figured you knew the software but the key words in my post was this " Connect the USB cable
end (USB symbol facing down) to the USB data
port located on the side of the Back-UPS. Connect
the other end of the USB cable to the USB port on
the rear panel of the computer."

Which states you should have a usb to usb cable and your backup unit has a usb connection on it. So buy a usb cable at any computer store and hook it up and you should be good to go without having to make any cable. I didn't find anywhere in the manual stating a RJ45 connection, only 2 RJ11 connections for a phone cord surge protector.

this unit has 2 RJ11 connections for phone surge protection and an RJ45 jack for the data interface...not a USB connection...i just got in touch with the guy i bought them off and he is going to see if they have any of the cables...so i might not have to make one at all!

Yep I have never heard of a small APC UPS having an RJ45 for Power chute. I have 11 UPSes all APC 500VA and up they all use com ports for the power chute software. Why would they use an RJ 45 when most people use there RJ45 connectors for surge protection on there incoming LAN cable. Like I said could be wrong but just does not make sense to me. My newest on 700XL still uses com ports.
