New install of Mesa 7i92 on TCL lathe

I'd just suggest keep going here as it can be built on as your build thread to sort out any issues.

The mesa firmware is all contained within this folder:
www.mesanet.com/software/parallel/7i92.zip

I won't post the firmware here as it's always best to just download the latest firmware folder from the Mesa site in case something changes or is updated

open up the zipped folder and navigate to (easiest to do it on a windows machine.... or you will be using the terminal to open the zipped file which unless you get used to linux and the terminal will be slower in my opinion):
7i92.zip\7i92\configs\hostmot2

If you look at the *.pin files with a text editor (such as notepad or notepad++) then it will show you the pin configurations for each of the ports at the bottom of the document.

Basically you have a few choices and options for the 5 axis chinese BOB.

I would suggest that you look at the 7i92_5ABOBx2D.pin file and you want to install the 7i92_5ABOBx2D.pin file as it will provide you with:
PWM on Pin 1 (don't think you will need it)
Step and Dir on pins 2,3,4,5,6,7,8.9
Input on pin 10,
Pin 11 as Encoder A
Pin 12 as Encoder B
Pin 13 as Encoder Index
Pin 14 as general Output
Pin 15 as general INPUT
pin 16 and 17 as the 5th Axis for the 5 axis card / Bob.

It does not matter if you plug the bob into P1 or P1 on the 7i92 as long as you set up the config correctly in the PNCCONF to use the right ports and pins for your needs.

IF your encoder only has 1 wire for A, 1 wire for B and 1 wire for the Index (I) it will be a single ended encoder.... just wire up to the pins 11, 12 and 13 as listed above.  (if it had 2 wires for each output it would be a differential encoder)
 

First things first.

Decide what Input & Output you need. Would you be requiring the same setup as you used for your Parallel Port Conversion ?

An example might be the following:
X & Z axis, Spindle Out, Spindle Encoder, Limit Switches, Home Switches, Manual Pulse Generator (one for each axis or one shared via a switch)

Or you just may want to use the 7I92 to have the same pins as 2 Parallel Ports. Which would more or less allow you to plug in any existing Breakout Boards without any changes to the wiring.

Once you have a list of the required I\O a suitable firmware can be suggested.

With regards to Differential or Single Ended encoders, Basically a Differential or Single Ended encoder can be used with an input that can operate with a Single Ended one.

Most users are willing to help if you are willing to put a little effort in. Saying it's too hard and throwing your hands up in the air is not the way to go. Age is no barrier to learning, listening to normies that say "Liniux is too hard" is a barrier. And be aware that most say "Linux is too hard" would have trouble doing some of the tasks that simple under Linux on Windows. And no, "Being a programmer" is not a prerequisite to using Linux.
Is anyone born knowing how to use Windows ? No, they have to learn.
Were you born knowing how to use a lathe ? No you had to learn that.
Were you born knowing how to use CAD or CAM ? No you had to learn.

Many years ago I was shown a  bunch of characters , a,b,c,d,e,  etc   and  I learned to use them to make words  which have been useful throughout my life, and have served me well.  I now know some big words like "condescending" and  "patronising"
You are right that many users are helpful and constructive  and most do not feel obliged to add the above type of comments to their contributions .
When I see such it turns me off, so that I place far less value on the the rest of the post .  If you are unable to refrain then dont  bother posting as i may not even bother to read it. 

Right so update :-
I discovered had included a misprint in the file so it was not being recognised .
That corrected I find that I now have communication and ping 192.168.1.121 is successful. Thanks to those who have guided me through this .
I still have a problem though in that I am now unable to connect this machine to the internet at all . I know I cant connect to both simultaneously, but even disconnecting the mesa and replacing with ethernet cable from my router I am just getting an error message from firefox ,
Is this a normal result of changing the ip on the host machine ??

It is quite a problem if i cant download stuff

No eBay APP ID and/or Cert ID defined in Kunena configuration

John you can get a usb wifi dongle for about £3


Then you can set up another connection for it.

I did reply to your PM

get a cheap usb WiFi dongle for internet connection. the ethernet is much more important for dedicated regular CNC communication
