Think of it this way -- a serial cable is like a composite television cable. You plug it in and it shows up on the TV, more or less. There's not a whole lot of fiddling.
A network cable is more like an antenna cable. If you plug it in and see nothing, maybe you're on the wrong channel, band, protocol.... It can carry lots of different things at the same time, you have to select what you want.
This is why you can't just 'cat /dev/ethernetdevice' and see the raw data from your data logger. You need to know what IP address and protocol you want to get data from, and have to have your computer configured correctly to read it.
Is there a way it's supposed to be used? Absolutely but we don't know what it is yet since all the information we need to know is missing. You've refused to answer all our questions.
You've been asked repeatedly for information about the device you're trying to log from. What is it? What model is it? Chances are the device will not log information until you make a TCP connection to it. It might use telnet or it might use http or it might use something else. The information may be in its manual.
When you tried to make a network, presumably to talk to this device on, we asked you repeatedly what information you had for the various things on your network. Several working, cooperating pieces all correctly configured are are required for a working network; knowing one computer's settings is less than half the story.

apcsmart
APCSMART(8) Network UPS Tools (NUT) APCSMART(8) NAME
apcsmart - Driver for American Power Conversion Smart Protocol UPS equipment NOTE
This man page only documents the hardware-specific features of the apcsmart driver. For information about the core driver, see nutups- drv(8). SUPPORTED HARDWARE
apcsmart should recognize all APC models that use a serial protocol at 2400 bps. This is primarily the Smart-UPS and Matrix-UPS lines, but some Back-UPS Pro models are also supported. Some older hardware may only report a handful of variables. This is usually not a bug - they just don't support anything else. CABLING
This driver expects to see a 940-0024C cable or a clone by default. You can switch to the 940-0095B dual-mode cable support with the cable= definition described below. If your 940-0024C cable is broken or missing, use this diagram to build a clone: http://www.exploits.org/nut/library/cables/940-0024C.jpg EXTRA ARGUMENTS
This driver supports the following optional settings in the ups.conf(5): cable=940-0095B Configure the serial port for the APC 940-0095B dual-mode cable. sdtype=num Use shutdown type num, according to this table: 0: soft shutdown or powerdown, depending on battery status 1: soft shutdown followed by powerdown 2: instant power off 3: power off with grace period Modes 0 and 1 will power up the load when power returns. Modes 2 and 3 will keep the load turned off when the power returns. BUGS
Some older APC UPS models return bogus data in the status register during a front panel test. This is usually detected and discarded, but some other unexpected values have occasionally slipped through. AUTHOR
