EXAMPLE
Input 1
Object
By default there is no offset and input 1 may be taken as the reference point beginning at channel
1 of the output stream. Channel 1 is therefore the FIRST CHANNEL. Since the desk used in the
example only has 256 channels, it can be assumed that channels 257 to 512 of the 512-channel
DMX signal will all be at level 0. Such information has no value, so we can set channel 256 as
LAST CHANNEL .
Method
Display shows 'run'.
Press button I1. Display shows 'in1'.
Press FIRST CHAN. Display shows '001'. If it shows any other channel no., use the ± buttons to
select channel '001'.
Press SAVE.
Press LAST CHAN. Display shows '512'.
Press '±' to change the channel number until '256' is displayed.
Press SAVE. Display shows 'Sto' and then reverts to 'run'.
Input 2
Object
We want the output from our 24-channel DMX desk to follow on after the 256-channel controller.
We therefore need to program an offset to begin output at channel 257. Since the desk gives 24
channels of meaningful output (and the rest of the 512 channels of the DMX signal will be output
as 0), we can truncate the output to 24 channels.
Method
Display shows 'run'.
Press button I2. Display shows 'in2'.
Press FIRST CHAN. Display shows '001'.
Press '±' to change the channel number until '257' is displayed.
Press SAVE.
Press LAST CHAN. Display shows '512'.
Press '±' to change the channel number until '280' is displayed.
Press SAVE. Display shows 'Sto' and then reverts to 'run'.
Analogue
Object
We want the output from the 12-channel analogue desk to follow on after the 24-channel DMX
desk. We therefore need to program an offset to begin output at channel 281 and finish at 292.
Method
Display shows 'run'.
Press button Ana. Display shows 'AnA'.
Press FIRST CHAN. Display shows '001'.
Press '±' to change the channel number until '281' is displayed.
Press SAVE.
Press LAST CHAN. Display shows '24'.
Press '±' to change the channel number until '292' is displayed.
Press SAVE. Display shows 'Sto' and then reverts to 'run'.
NOTE: The analogue FIRST CHANNEL and LAST CHANNEL must be no more than 24 channels
apart; any channels greater than analogue FIRST C 24 will contain unpredictable data.
