Elizabeth is quite right. It's easy to get collisions on the IR "bus" if two devices are sending (or replying) simultaneously. What I've done in the past with two RCXs is define one RCX as primary that is periodically (every 100 to 250 milliseconds (...) (18 years ago, 2-Apr-07, to lugnet.robotics.rcx)

RCX IR does not require direct line of sight. All sorts of reflections will work. Especially if you're in a "smallish" (bedroom, home office) room. The RCX firmware always has the IR turned off. "Wait for mail" and "send mail" is just a higher (...) (18 years ago, 2-Apr-07, to lugnet.robotics.rcx)

IR communication is no where near the reliability like a tcp/ip. You can easily lose a message ... so program must be either extremely simple one way communication. The sender should be programmed to handle message loss. What I had the kids done was (...) (18 years ago, 2-Apr-07, to lugnet.robotics.rcx)

(...) Thanks for your reply. I had to return the 1.0 RCX and motor back to school today. Those things are like gold. The 1.0 faces the 2.0 and is not in direct line of sight of the tower. The 1.0 is just to the side of the tower. I think my problem (...) (18 years ago, 2-Apr-07, to lugnet.robotics.rcx)

Are you sure your problem isn't interference? How did you "lock out" the RCS 1.0 from receiving (and responding) to the direct commands? You have two RCXs turned on and sending direct commands from the PC. They will both try to respond to the (...) (18 years ago, 2-Apr-07, to lugnet.robotics.rcx)

I have been running RoboLab 2.54 B on a Dell Inspiron 1100 with little problem until of late. I am using direct mode, tower set to high and the 2.0 RCX and tower are 3” from each other with the 2.0 RCX raised up 1” to better line up with the tower. (...)

Has anyone had success in installing RoboLab on a server? After installing on a windows based server the message "visa32.dll is missing" occurs. Assuming RoboLab 2.9 can be run from a server are there any maximum user limitations? (18 years ago, 15-Mar-07, to lugnet.robotics.rcx.robolab)

But then it reports the error I provided earlier. (...) (18 years ago, 13-Mar-07, to lugnet.robotics.rcx, FTX)
