By Definition, When Downloading, You are Wiring your HECC80 Control and It's CPU Circuit Board to an Outside Device. The CPU Board is Quite Susceptible to Voltage and Ground-Loops which can Easily Burn-Out this Board.
To Minimize this Problem, Follow My Recommendations. Or, if you wish to do it Your Way, I will be Happy to Repair your CPU Board as Many Times as you Wish.
1 -- Locate the Downloading P.C. Computer Right Next to HECC80 Control as a Local
File-Server Dedicated to This Machine Only. Do Not Run Cable to your Office!
2 -- Use a Short, 8-Foot Long RS232 Cable. Do NOT Use A Long Cable! Do Not Run
a Long RS232 Cable from a Remote P.C. Directly to your HECC80 Control!
3 -- Plug Both P.C. Computer And The CRT-Monitor Power-Plugs into
A.C. Power-Strip Inside the Strippit Houdaille HECC80 Control !!!
4 -- Do NOT get Power from a Wall-Outlet! Do NOT use an Extension Cord!
5 -- Obviously, Outside the North American Market, you Can Not Do This as Your
P.C. Computers will Require A.C. Power with Different Voltages & Frequency.
So you Will Have to Make a Ground-Strap to make sure Grounds are Equalized!
You will Still Locate your P.C. Computer Right Next to your HECC80 Control.
Take a 8-Foot Long piece of 14 or 16 Gage Wire and Solder a Ring-Terminal on
Both Ends. Attach 1 End to a Metal-Screw on the Back of your P.C., Attach the
other End to a Good Electrical Ground-Point inside your HECC80 Control.
Make Sure you have Good Solid Electrical Ground Connections on Both Ends!
6 -- Do Not "Share" Downloading P.C. Computer with Another Machine!
7 -- Do NOT use a RS232 "Switch Box" to "Share" Downloads to another Machine!
8 -- Make sure a 8-Foot Ground-Rod is Installed at the Back of Each CNC Machine!
9 -- Locate Welders, and Especially Hi-Frequency TIG Welders and Plasma Cutters
as Far from all CNC as Possible!!! At Least 60 - 100 Feet away,
and Farther is Better! Nearby Welders Do Cause Many CNC Control Problems!
10 -- This Would Seem Obvious, But
Never Plug-In or Un-Plug a Cable or Circuit Board when the Power is On!
This Risks Damaging Both your P.C. Computer and your CNC Control!
Always Turn-Off your P.C. Computer And your Strippit's CNC Control First!
11 -- ILLegal Characters;
For The HECC80/1 Types of Controls;
--- All Characters Must be Capital-Letters Only, No Lower Case!
--- The Complete Alphabet is Not Supported.
Only the Characters 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, D, F, G, I, J, L, M, N, T, X, Y, /, ., +, -, and the "Hidden-Characters" for "Carriage-Return", "Line-Feed", and "Null" are supported. All Other Characters will Generate a "Illegal Character" Fault Message!
For The HECC80/3 Types of Controls;
There are Different Versions of HECC80/3 Software, and some of them Handle Characters & Filenames Differently. These Different Software Versions are Poorly Documented, and it is Hard to say which one does what.
--- In General, the HECC80/3 Controls will Automatically Convert Lower Case to
Upper Case Characters with No Errors.
--- The Full Alphabet Is Supported.
--- Unlike the HECC80/1, HECC80/3 Controls Support and Need Transmitted
File-Names. But, Do Not let Your File-Sending Computer's Software Send
Directory and Sub-Directories Preceding the File-Name!
--- Keep File Names Short, Simple 8-Characters Names are Best, like XYZPART3
--- File Extensions are usually permitted, like XYZPART3.CAD
But, I would NOT use them. Apply the KISS Principle, Keep it Simple Stupid!
There Are Many Other Notes, Recommendations, and HECC80
