Subjectproblems with MAX and tcp/ip
FromJeff Lieberman
DateTue, 28 Jan 2003 23:08:09 +0100


hi-

I recently bought a lanbox LCX, and am trying to get it to respond to commands issued from MAX through the tcp/ip demo program.

However, it is not working.

When i connect to demo.lanbox.com, everything apparently works fine- i get asked for a password, i respond, it says connected, and then it responds with '62' when i move around the sliders. So, I am assuming that things are moving over there.

However, when I move things and switch the address to 192.168.1.77, it's very different. I still get asked a password and it still responds   if i'm correct as 'connected'. So it's definitely communicating on some level. But it responds to every movement of a slider with '63', and I don't know why. The yellow light still flickers when i move a slider around, so the message is getting over there. Maybe the lcx is just a different protocol or something, or the firmware is newer than the max program? I really don't have enough of a background with this box to have a feel for what is wrong, and it's just getting frustrating.

Considering I do not plan on downloading programs to the box, and just want it for real time control of servos and lights based on sensor inputs, does anyone have the simplest patch possible that will work for the lcx box and max through tcp/ip, that i can later extend for my uses to multiple channels and things? i really don't have too much time to get all this set up, and it's not working!

[A side question- I read in some part of some letter from this list's archives, that the box will only output like around 10 frames of dmx data per second..  is that true? I am controlling movement of servos that need to react fast and i'm worried that if i for example want them to move from extreme to extreme in like one second, that the motion might be very jittery.]

Anyway, help in the tcp/ip matter would be most appreciated. Thanks.
