I want to build a RS485 network using Cat 5 cable. But since the RS485
specs don't specify connector types I'm at a loss to figure out what I
should use with (easily obtained) Cat5 cable.

Some of the remote nodes attach to equipment that is on wheels (ease
of moving for cleaning, maintainance etc). So I'm thinking that the
cables and connectors may get damaged over time. I would like to use
cables and connectors that are cheap and easily replaceable when
damaged. (Yes, I know the best thing is to ensure that they don't get
damaged in the 1st place, but this is the real world I'm talking
about).

This is half duplex RS485 communication, so it only requires 2 diff.
signal wires and ground. (A total of 3 wires).

I don't want to use a RJ45 connector on the Cat5 cable, as somebody
might think it's an Ethernet network cable and plug it into a laptop
or something.
I like RJ45 as it enables me to use standard patch cables - and easily
terminate all conductors when making custom stuff... The connectors are crap
when lying around (the tab dies) so if one needs a more sturdy construction
I'd opt for the XLR-style RJ45 or perhaps the Harwin (or similar) industrial
ones.

It occurred to me that RJ11 cable has 4 wires, and might be the
solution to my problem.

What I was thinking of is to run Cat5 as close to each machine as
possible and connect it to a plain old surface mount modular RJ11
telephone box (you know, like what your phone cord plugs into). Then I
could use a standard RJ11 telephone cable (like what connects your
modem to the phone line) to hook the machine up to the network. (The
machine would also have a modular RJ11 telephone box which would be
connected to the RS485 transceiver of the electronics that I'll
design).
Not a problem if it's short. And definitely not at 9600 baud. If it's a
noisy environment you might miss the shield though....

2. What about if I use a slew-limited RS485 driver on all nodes to
help ensure signal quality (minimise reflections etc). Will I be able
to do this RJ11 thing then?
Always use slew rate limited parts when possible!

3. Are there any other cheap connectors and cabling that I can use for
Cat5 to run it directly to each machine? What type of connector do you
guys use when you do RS485 networks and how do you handle the physical
wiring arrangement? (Digikey #s appreciated if possible).
I use micromatch and ribbon cable!

Thanks for any advice/suggestions.

Laptops routinely use USB as an internal interconnect, particularly for
WLAN cards and for built-in flash memory readers. They generally seem
to use 2mm pitch pin headers on the PCB and rather thin shielded cable
(similar to the type of cable used for off-the-shelf CD-ROM audio
cables).

Cambridge is IP-driven and, IMO, has seen very little off-shoring.
The
only exception I'm aware of is some digital IC verification which has
gone to Bangalore, but I would be surprised if this was more than 20
jobs. A bigger problem is, I think, offshoring to the US. Companies
get taken over, and the jobs eventually go with them.
If it's any consolation, once EU engineering jobs move here to the US
they are on a fast track back out to India. The process and thinking
appears to go like this:

1. We (US corporation) acquire company A in EU for some juicy nugget of
IP, slice of goodwill, or maybe just a customer list they own.
Marketing and distribution arms of the EU company are clearly deadwood,
not part of our global strategy, and they're offered internal
recruitment (maybe) or laid off.

2. We try to write translation firmware to integrate their products
with ours. During this process we need their engineers to be working
fulltime over there in sunny Europe. However, it quickly becomes
apparent that it is less trouble to redesign the EU subsidiary's 10
flash-micro-based products to be compatible with our 5,000-item
mask-ROM-and-ASIC product line than it is to build shims between our
protocols and theirs.

3. Management says "Well, these products were always being managed
non-domestically, so whether in Europe or India it will be no more
difficult to manage them. They all need major firmware rewrites. All
the US engineers are fully loaded already, and the EU engineers are
expensive and don't have experience with our protocols anyway. Let's
give the porting job to our Indian or Chinese subsidiaries".

Poppycock.

My wife relies on me for mechanical, cartographic and analytical

I forgot, or need, and supply it. And most important, she helps
me to be a human, to love and to appreciate others. In turn, she
relies on my love for her, and for my watching out for her needs.
Speaking of which, I'm off. :>)
Similar thing here. I fix the plumbing and in return have a never

I've no doubt it's got a web page. Have a look; don't rely too much on

We have an RS-485 network that uses CAT5 cables, and have yet to have
anyone plug a laptop into it (that I know of), and at 1000 plus networks
installed so far, that's pretty good. I think the most important thing
here is that I don't see that attaching an ethernet device to the net
would do anything other than not work and possibly drag down the RS-485
network. We use slew rate limited, failsafe, with short circuit
protection drivers and everything has been goin along great. I know it
is always a good idea to design the possibility of an idiot doing
something dumb out of a system, but in this case I really don't see it
as a problem. If you are REALLY worried about it have get some cable
tags and mark the CAT5's with RS-485 or maybe some scarely warning about
hooking to computers.

It shouldn't. From the moment of conception, when the two foreign

Complete nonsense. We only need you be concerned about a "life" after it
has first become *conscious*. Before something becomes conscious it is
no more then a carrot. What *makes* a life, that needs consideration for
its *own* sake, is a brain. Period.

Utter hogwash. Killing a live, growing organism which will eventually
become sentient for no other reason than to prevent it from becoming
sentient is murder, pure and simple.
---

I suppose this depends on the definition of "murder". Is it a legal one,
or one what we personally consider is murder. For me, certainly before
about 3 months there are simply no significant neuron connections in a
brain to make a conscious mind, so until that time, the foetus is no
more than a carrot.
---
While for me, it's important to let the carrot _become_ a carrot
before it's yanked out of the ground.
