Taking the Time to do the Firmware Right.


Welcome to our pages on Errata -- where we confess our Blunders and Mistakes we make on this Website, and the Corrections. We would like everything you see to be error-free, but we're only human. (Incidentally, if you find something wrong, drop us a line, and we'll credit you for the spot.)

  • E00001 : In the "How to set up the `Set Operating Parameters' feature", and "How to set up the "Small Corrections" feature" on Commanders. We said the "Use the old, old ARC 1000 communications protocol" Operator Option is on Line 1. It's not. It's on Line 3.
    Here are the expanded versions:

  • E00001 : In the "How to set up the `Set Operating Parameters' feature", and "How to set up the "Small Corrections" feature" on Commanders. We said the "Use the old, old ARC 1000 communications protocol" Operator Option is on Line 1. It's not. It's on Line 3.
    You can set up various Auto Register features, values, and operations by means of the "Set Operating Parameters" feature. To set up the "Operating Parameters," start out by simultaneously pressing and releasing the two middle keys of the Operator Station Keyboard on the third row from the top.

    The first (left-hand-most) parameter on line 1 was erroneously marked as "Use the old, old ARC 1000 communications protocol." It was never that. It was unused until nc_regis (i.e. the Registration Controller) Version 1.9, when we made it a flag to "Gong using an inverted signal."

    The first (left-hand-most) parameter on line 3 was NOT USED prior to nc_regis (i.e. the Registration Controller) Version 1.8. With Version 1.8, we recognize the option "Use the old, old ARC 1000 communications protocol," but as of the latest version (1.9e) it really doesn't do much. It's intent is to imitate a controller on an old ARC 1000 registraiton system, so you can intermix the old ARC 1000 register control with the new, to gradually up-grade an old Commander from the old ARC 1000 to the new Auto Register. But we've found limited enthusiasm for this, so it's incomplete.
