5. ID
Numeric characters are used to identify an individual Projector when two or more Projector units are
connected to a single control machine.
Setting separate identification numbers for each Projector allows independent control of each
Projector unit.
# Assignable ID numbers
‘0’(30H) ‘8’ (38H)
‘1’(31H) ‘9’ (39H)
‘2’(32H) ‘A’ (41H)
‘3’(33H) ‘B’ (42H)
‘4’(34H) ‘C’ (43H)
‘5’(35H) ‘D’ (44H)
‘6’(36H) ‘E’ (45H)
‘7’(37H) ‘F’ (46H)
* Factory set ID is ‘1’ (31H).
ID number ‘0’ (30H) should be used when assigning all connected Projector units for batch operations.
This means that when assigning independent ID numbers to multiple units, 15 of the 16 assignable
numbers (from ‘1’ through ‘F’) can actually be used for registration.
Please note that tally (response) data is not returned from the projector when the global ID assignment
function (0) is used.
