Dual GCX, single control switcher, ground control and disappointment

Post by Sconley666 » Thu Sep 20, 2018 8:09 am

Greetings

I’ve used a gcx and ground control forever with great success. I just bought another gcx and the control switcher to expand my rig. I am totally disappointed because it seems to me (and I could be wrong) that I cannot use the additional gear without a firmware upgrade to my ground control which is version 1.01. Help! I just spent a pile of money and now what? I am crafty with a soldering iron. Where do I get the upgraded ROM chips for my ground control?

Do you have the original 12 button Ground Control OR the 15 button Ground Control Pro?

I’m sorry it is the original 12 button

Do I need to also be concerned that my original gcx is different looking from my new one? My old one says ground control system and dmc instead of voodoo lab

OK, so your original Ground Control (I'd guess about 25 years old!) does need an update in order to control multiple GCXs. This ability was introduced with the v2 Firmware launched in the mid 90's.
Your older GCX may also need an update to be able to be used in a multi GCX setup. The way to know what version firmware a GCX has is to note the direction the LEDs light up when first powered up. Left to Right would be v1 Firmware and will need to be updated. Right to Left would be v2 Firmware and would not need an update.

Now for the best part... We still support these products! Please give us a call or write to info@voodoolab.com so we can get the necessary update chips ordered and sent out to you.

I hope that helps alleviate some disappointment ;)
