Hi, Im programming an AMX controller that has 2 DELL5100MP Projectors connected on serial,
both on different ports, at 19200,n8,1
Now I have the document from AUG 2005 on the RS232 Protocol Pin Assignment

 

But i get responses that are not documented.

What I do is

SEND POWER ON TO PROJECTOR

GET OK

wait 61 sec for heating

SEND SET AUTO SOURCE ON (I Found that if AUTO SOURCE is off the INPUT is NOT CHANGING)

WAIT 0.5 SEC

SEND SET COMPOSITE

wait 0.5

SEND AUTOSOURCE OFF

 

Now the strange thing is the Projector sends data after 20sec from the pwr-on

BE EF 10 09 00 70 17 33 33 05 00 D1 41 31 30 30

This is NOT documented where to get more info on the RS232 Protocol

 

Below an DUMP of my log.
