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
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 Machines 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
RS232 Set-Up Data Included With Our Tested RS232 Cable Kits.
If you have Never Set-Up a RS-232 Download to a Strippit
HECC80 Control, We Strongly Recommend that You Use Our Kit!
