A Ddressing Of M Ultiple B Oxes (Rs485) - RayTek MI3 Operating Instructions Manual

ASCII Programming
Examples for the head command "Emissivity":
?2E requests the emissivity for sensing head at address 2
2E=0.975 sets the emissivity to 0.975 for sensing head at address 2
!2E0.975 sensing head at address 2 confirms the emissivity setting
18.8 Addressing of Multiple Boxes (RS485)
Up to 32 communication boxes can be connected within an RS485 network. To direct a command to
one box among the 32 possible, it is necessary to „address" a command. Therefore, a 3-digit number is
set prior the box command. The 3-digit number is determined between 001 and 032.
XA=024 will set address to 24 (box must not be in multidrop mode)
Changing an address:
(e.g. the address is changed from 17 to 24)
command answer
„017?E" „017E0.950"
„017XA=024" "017XA024" setting of a new address
„024?E" „024E0.950"
Note: A box with the address 000 is a single box and not in multidrop mode.
If a command is transferred, starting with the 3-digit number 000, all boxes (with addresses from 001
to 032) connected will get this command – without to send an answer.
command answer
"024?E" "024E0.950"
"000E=0.5" will be executed from all units, no answer
"024?E" "024E0.500"
"012?E" "012E0.500"
