Subject: "show scene" permanently overwrites DMX channel
From: Philipp Gysin
Date: Wed, 30 Oct 2002 11:09:12 +0100

Hi there

I noticed a behavior of the Lanbox which is not consistent with my
understanding of the priority of the engines.

Let's explain it in a simple way ;-)

i)  I start to show a scene in engine C with some channels set to some
values.
ii)  From now on I continuously set channel values in the same engine via
TCP/IP with *C9 03 ch# val [..] #
       (I hope 03 means engine C)
iii) If I get a specified value on the I/O port, I jump to another cuelist
in engine B which sets DMX channel 5 to 000 until the trigger on the I/O
disappears
iv) As soon as the script returns to engine C (go s#.st# in engine C), step
ii) is valid again, that is, the values are set via TCP/IP

What I don't understand is that if I have some value in channel 5 step iii)
correctly overwrites it (engine B has higher priority) but when it returns
it doesn't restore the previous value. (?) I thought the channel would just
temporarily be overwritten....


Here the full scripts:

ENGINE C (list 5)
========
show d01 for 1.0s
002:
hold for 2.0s
show d03 for 1.0s
go 001 if input 8 within 0-512
go 002
001:
go 10.1 in engine B

:d01
1[255] 2[000] 3[000] 4[000] 5[255] 7[000]
:d03
1[255]

ENGINE B (list 10)
========
show d01 for 2.0s
002:
go 001 if input 8 within 1000-1024
go 002
001:
go 5.2 in engine C

:d01
5[000]


Any clue what it could be ?

Thank you very much for your help

Philipp
