Directly, as in one port? I need to monitor multiple alarms and need
multiple ports, as in 8 or more.

Translator adapters RS232/RS485 can be purchased for about $25.

serial port, you got two pins, and for a parallel, you got 8-10, IIRC.
Using direct IO. You read the port and see the logic state if the pins...
No buss involved..
Another option is a Dallas ds2490 (?) USB to one wire adapter buss
(~$25). Then, with ds2401's or DS2405's (~$2 each) you can sense a
bunch of spots, but the SW to do so is more complex. I've had my best
luck with the Linux version of the Dallas SW than the windows version...

WTF is a "buss"? (obviously you work in the electrical field)

Manufacturer of fuses, and probably a bunch of stuff I'm not aware of.
Also (and I don't know if this comes from the manufacturer, or some
alternate source), a "buss bar" is a power or ground bar in a circuit
breaker panel.
The name has leaked over to become an occasional alternate spelling of
"bus" -- it happens enough I'm not even sure I'd call it a mis-spelling.

Buss is an old word for kiss. A data bus (only one "S" here) is an interface
between a computer and another computer or some other device to exchange data.
It can also refer to a data connection between components within a computer.

How many feet can a USB cable be run before it ceases working even
at the slowest USB speed? If I need to run the cable to the front
door, back door, refrigerator, freezer, garage doors, every window,
some motion sensors, a couple of smoke alarms, and a keypad, that's
a lot of cable. On the other hand, polling each sensor 5 times a
second is probably way overkill.
Four USB-to-parallel-port devices, with the parallel-port devices
(with data and control lines, you may be able to sense 10 contact
closures each) spread around the house, might be sufficient.

Sorry, but you can't use those devices the way you mention. They
only work with print drivers.

You may want to look at using rs232 boards like below and use it
with a USB to serial adapter. Be aware that USB boards (like
bottom activewire) that do not apper as a serial port but instead
use dlls and such, can require significant programming
experiance.

This appears to be an ideal solution (or at least close to it) for a project
using a PC to monitor and control alarm sensors, sirens, etc. The gentleman
will also need a power supply to operate motion, smoke or glass break
detectors as well as for sirens or strobes.
I don't sell this device and I have not tested it so due diligence, please. I
do sell power supplies, alarm detectors and such in case the OP needs a source
for same.

Do you need/want to absolutely restrict access to a single computer? If not,
my preference would be for TCP/IP-based ( not usb, not RS-xxx, not bus).
WebControl is a $35 TCP/IP-based (web) device that I use and can recommend
that would give you 8 TTL in, 8 TTL out, 3 analog in, multiple 1-wire
temperature input, HIH-xxx humidity sensor input, etc:
Input
Digital Inputs 8
Analog Inputs 3
Maximum Digital Input Level TTL 5V
Maximum Analog Input Level 3V
Mnimum Input Level 0V
Output
Number of Output 8
Output Level TTL 5V
Output Current MAX 30 mA
Programmable Timer
Number of programmable timer events 20
Sensors
DS1822 Temperature Sensor 8
Honeywell Humidity Sensor 1
Power Consumtion
Without Load 5MA
With Full Load 240MA
Power Supply
DC (recommend) 6V to 7.5V
AC (when DC not avaliable) 12V

I have two boards of an earlier version (hardware 2.02) than what is now
shipping that was fussy about the exact 1-wire temperature sensor used. The
contact tech team was very responsive and had the firmware re-written by the
team in Britain.

My preference is also TCP/IP. I assumed that such a solution would be too
expensive. Thanks!!!

Yes. And one can create rules using Boolean AND/OR logic with the various
inputs including TTL-level logic, 0-10vdc analog, temperature, Relative
Humidity, and Date+Time and delay timers to control the TTL outputs. The Real
Time clock (RTC) can be kept accurate by Network Time Protocol (NTP).
I'm considering these as an integral part of multi-unit, open-loop geothermal
HVAC for our house. Hardware for RS-232 and RS-485 inputs are on the
WebControl PCB but are still unsupported by the firmware. I had a useful
conversation with the manufacturer about the potential to support BACnet.
They are up against memory constraints in the microcontroller.

At $35 including a steel case, IMO it's quite a bargain compared to some
other devices.

This type of device works. It allows for reading and controlling 16
TTL/CMOS lines:

And the drivers are a part of the OS.

with multiple take off points. There is and never was such a thing as a Buss
bar. "Buss" has always only been the name of a fuse company and is confused
by many electrical people. English words are usually only changed by
USanians.

I've seen too many references that are older than I am to buss bars to
categorically say the term is wrong. For all I know Buss used to make
Buss bars, and the former trademark has become generic.
(and just think how much easier this conversation would be to follow if
you'd continued in the steps of the previous posters properly trimmed

Buss makes fuses. The term is bus bar. It's a common mistake but that
doesn't make it an alternate spelling.

Oh, bullshit. Top post or bottom post as you like. I prefer to "mid-post"

I agree, but as long as we're going to be anal, it's "too anal" -- not "to

Sweet, just plug it into my LAN and go. Every room already has cat5
jack, plus wifi access and access from anywhere in the world.
I've slowly been switching everything over to TCP/IP, security
cameras, dumped all my home control software in favor of a little
universal devices Insteon box, Belden usb hubs that talk to tcp have
also let me plug my movie cameras and other usb peripherals in one
place but access them directly on the LAN as though plugged into local
usb, my music/movie library is networked with windows home server,
etc.
Yup TCP/IP is the way to go I just may use this unit with a relay to
remote boot up a computer I need to get to remotely occasionally
(since this gizmo has its own web server) the big box can stay off
till needed. I can just browse this little guy from the office and
tell it to boot the big machine. Now I no longer have to keep that
machine running simply because "I might" have to get to it from work
that day, nice. Glad I read this thread.

Yes I have seen the word used this way too, in fact in some old
electronic magazines.

A "bus" runs from one place to another on a line. "Buss" is a brand name.
People have seen this misuse so many times in the electrical field they all
start to believe it 'cause nobody ever corrected them.
If we allow this go on **till** (no such word in this context) a few months
pass the Americans will have to make a new entry in their dictionary. That
ain't (no such word at all) happening...LOL
