What PID's/ SID's/FID's are - Ralph L. Fullenwider - 02-06-2007 05:42
Hello everyone:
For those who are not familiar with codes, multiplexing or other forms of
reporting used in this day and age, I will attempt to bring to light a
little about these systems in the later Coaches.
The reporting codes and information are inputs and outputs much like on the
computer you are using for the Forum. And each code is simply an address of
where in a computer, the information is stored. So in order to get a
readout for that code, you have to have the input/output (I/O) schedule for
the addresses.
Though we see the codes reported in decimal (number) form, the actual
addresses are usually programmed in Hex or Octal or even machine coding,
then converted to binary and finally to numbers. In doing this, one wire
can be used to send a signal out on and to report back on several addresses
depending on the speed of the polling process.
The reason for the software, readers and so forth is to convert these
multiplexed addresses to a form that we can attach a number to and have a
readout of what code or instruction is in that address.
The codes are usually preset with a read out of what it is. Example: A
polling takes place sending out a question to a certain address, then if no
flags are set nothing comes back. But if an address, such as the DDEC
address for Low coolant is polled and a flag set, it sends back a number of
13. Then you look up the code on the map and it tells you, code 13 is
coolant level sensor low, add coolant and the flag goes off satisfied.
This is much simplified, to be sure, but the general idea comes across.
Easy huh? Hope this helps a little for those wondering what people are
talking about in some of the posts.
Safe travels,

Ralph, It may just be my nature but; I dont believe that all the
digital equipment is worth the worry. When I get a check engine
light; I check the engine. If the heat goes up; I back off the
demand. I have driven a good 400,000 on used class 8 diesel trucks
with as much as 700,000 miles on the clocks. Things do not often go
wrong and when they do:
1- it showes up in water/ oil heat and or performance
or
2-too late even while you watch a PC
digital stuff I see as more of a hobby.

Greg: You are 100% correct about the engine data program and the Hobby element,
and I personally don't need a cell phone, in motion satellite TV, remote control
HD flat screen, iPod, Two way radio, GPS, DVD, PSP, MP3, high speed cable
internet, Xbox, VMSpc, Bluetooth, PC wireless laptop, WiFi, Broadband, Federal
Income tax, State income tax, SUI, FUI, LUI, or even a Bluebird WB-40. That is a
lot of @#$%. Beer is good!
Except for the taxes, this day and age, the above make life a little more
comfortable wouldn't you say?

What PID's/ SID's/FID's are - Ralph L. Fullenwider - 02-06-2007 13:11
Greg:
I agree with the use of the KISS method and analog readouts.
I had a couple of back channel questions concerning some of the technical
talk lately and asked to shed a little light so more of an understanding
might be had. So I wrote a little blurb to do that.
The RV industry is behind the curve with technology but are starting to get
away from relay logic and going to multiplexing systems. Of course this
technology has been out for years in the industrial arena along with fiber
optics and 422 and 232 communications with up to 25 nodes on each single
conductor.
All the high line coaches are just now starting to pick up on some of this
stuff, The problem being, most of this technology was never meant to be
rolling down the road at 70MPH in a 40K plus motor coach.
Yep, give me the tried and true any day, but one has to keep up with on
going technology or get left behind.
blue tooth and how to program the VCR. lol

What PID's/ SID's/FID's are - Don Bradner - 02-06-2007 15:46
Ralph, I'm glad you posted your explanation - I'm not surprised that there were
questions.
As a 3-year user of VMSpc, I find the advantages to be several. First, my mind
processes digital data better. I see 65 MPH more readily than I do a needle
pointing at the corresponding spot on the analog gauge.
Second, I get data that is not otherwise available. I really like, for example,
to be able to see the cruise set speed, so I know when I hit resume what it is
going to take me to. Worked better on the last coach where that number was
retained between power-on sessions, but it still is good after spending 30
minutes passing through a town off the cruise.
The remaining thing is the ability to set yellow and red alarms at my own choice
of set points. I'm going to get a red light from coolant temperature well before
I'm in trouble, and I hope the same will be true for coolant level. My copilot
keeps an eye on the laptop, and alerts me the moment any status changes from
green to any other color, without her having to know what numbers are "bad"
ones.

Don, Input from the copilot is another thing I dont want in my bus.
T " its red"
G "whats red"
T "the thing you told me to watch"
G "...............what happened to yellow"
T "OK its yellow..........., now its red"
G "Whats Red"
T "Hold on, Its 4th and 3,.... RUN IT, DAM'IT RUN IT"
G " Run WHAT!, What the hell is 4th & 3 ?"
T " Florida vs WVU,.....I cant do two things at once,
you watch the PMS-pc thing your self"
G " Focus, we have a problem"
T " OK OK , it says Windshield fluid low"

That would have to come in while I was drinking coffee!!! Spfffft
My copilot enjoyed it as well.
