(...) The RCX has a bridge rectifier inside, that converts the AC to DC. It also has a voltage regulator that allows it to take a fairly large input voltage range. You can safely power it with a DC supply, however I wouldn't recommend leaving it on (...) (20 years ago, 31-Mar-04, to lugnet.robotics.rcx, FTX)

I must also be blind. In tiny raised print just above the port on the RCX, it says "9-12V~". Had I seen that I would never have asked my original question in the first place. But I'm still curious about whether the RCX runs on AC or DC power. Does (...) (20 years ago, 31-Mar-04, to lugnet.robotics.rcx, FTX)

(...) Wait, are you saying the RCX runs on AC power? You are right that the 12V adapter I got puts out AC. I didn't notice that before -- I thought it was an AC to DC converter. Then I checked my train adapter, and it's identical to the one I just (...) (20 years ago, 31-Mar-04, to lugnet.robotics.rcx, FTX)

I bought an RCX with an AC adapter jack and an AC adapter from Pitsco. They arrived today. But when I opened the adapter I saw that it outputs 12V, not 9V. It's an old Dacta AC adapter from 1996 (copyright date on packaging). I already tried using (...) (20 years ago, 30-Mar-04, to lugnet.robotics, lugnet.robotics.rcx, FTX)

I'm a little surprised that the Spybot doesn't need to see the packet header byte - the byte containing the range/orientation bits preceding the 0x8n Ping byte. The header is deliberately generated with the stop bit cleared to force a framing error. (...)
