User manual

The following table illustrates how the opto-isolators are used, with examples using opto-isolators 4 to 10:
MSB Optos in between Path Type Optos in between LSB Path
Opto 4
(binary 4)
Opto 5
(binary 2)
Opto 6
(unary bit)
Opto 7
(binary 8)
Opto 8
(binary 4)
Opto 9
(binary 2)
Opto 10
(unary bit)
0 0 1 1 = Main 0010MAI3
0102=Aux1111AU16
0113=Ext0110EXT7
1 0 0 4 = Group 0011GRP4
1015=Cue0000CUE1
SLS SELECT VALID
This is used to execute routing of the path to the Studio Loudspeakers, as selected with SLS SELECT MSB and SLS
SELECT LSB.
HEADPHONE SELECT MSB and HEADPHONE SELECT LSB
These are used to specify a range of seven opto-isolators that represent a source for the Headphones in binary
form. The opto-isolators should not be used for anything else. The LSB opto-isolator number must be after the
MSB opto-isolator number.
The usage of the seven opto-isolators is identical to the format used for the Studio Loudspeakers.
HEADPHONE SELECT VALID
This is used to execute routing of the path to the Headphones, as selected with HEADPHONE SELECT MSB and
HEADPHONE SELECT LSB.
SNAPSHOT SELECT MSB and SNAPSHOT SELECT LSB
These are used to specify a range of opto-isolators that represent a Snapshot number in binary form. The
opto-isolators should not be used for anything else. The LSB opto-isolator number must be after the MSB
opto-isolator number (see example below).
The number of the Snapshot is as it is numbered in the current Snapshot file (see Filing, page :, and Snapshot,
page :).
The MSB (most significant bit) is the highest digit in the binary number and the LSB (least significant bit) is the
unary digit (i.e. the 'ones' column of the number). Each opto-isolator represents 1 when it is closed or 0 when it is
open.
The following table illustrates an example using four opto-isolators (13 to 16) for snapshot numbers:
MSB Optos in between LSB Snapshot
Number
Opto 13
(binary 8)
Opto 14
(binary 4)
Opto 15
(binary 2)
Opto 16
(unary bit)
110113(8+4+1)
01004
SNAPSHOT SELECT VALID
When the specified opto-isolator closes then the snapshot will be loaded, according to the number identified by
the opto-isolators in the SNAPSHOT SELECT MSB to SNAPSHOT SELECT LSB range. If relays are assigned to
show the selected Snapshot and if it is valid then they will close.
