Redpower 2 question

[JohnnyX]

So I just made a frame aircraft and put lots of computer monitors in to control it with one PC. Each time i open the pc only one monitor responds and is operatable. What can i do to make all of them work? Here are some pics that might give you a better image of the issue.

Each monitor should have a different Bus ID, and the program should be able to select which monitor it is talking to, but there's a bug in RP2 that prevents you from setting them. You should be able to right-click on the monitor with the screwdriver and set the dip switches. There's a patch mod called Redpower Tweaks that fixes this bug and a few others e.g. the canvas bag dupe bug and the muliple drops from breaking IO Expanders and RAM packs.

Thanks for the advice . With which command do i switch the id of a monitor without restarting the computer?

I think you write a value to TERMADDR (e.g. 10 TERMADDR !). So you'd have to somehow tell the CPU which monitor you want it to interact with, maybe a button by the monitor that sends a bundled cable signal to the CPU switching it over to that monitor.

Is it possible only with a command?

Yes, but how do you execute that command? You could use the currently-active terminal to tell the CPU to switch to the next terminal that you're about to go to, but that's not very useful if you just want to use this terminal right next to you right now without having to work out which terminal is active and go to that one to tell the CPU to switch to this one.

I dont mind . When i used the command nothing happened

So you managed to set the Bus IDs of the monitors to different values? I'm afraid that that puts you into unknown territory, as I've not used RedPower Tweaks. I tried it out briefly on an SSP test world but my main world is on a hosted server and I didn't want to mess with the server mods. It's entirely possible that there are other bugs that affect terminal address interaction, it's also possible that I'm wrong in saying that you set the monitor ID by just writing to the TERMADDR variable.

You should always try out these basic concepts in a simple test rig before building a complex frame machine that relies on unknown behaviour!
