A1.1.4 Replacing SD Racks with DiGiRacks ................................
If you are connecting racks with Optocore and your session originally used SD Racks, you can replace these with Optocore connected
DiGiRacks or MiNiRacks as follows:
Note: Optocore V220 cannot run at 96Khz.
If you intend to use a 96Khz SD Rack (V221) session with DiGiRacks (V220) then the session should be Restruc-
tured at 48KHz and saved as a New File before attempting to downgrade the Optocore Firmware and proceeding.
1) Ensure that the SD Series console is running Optocore Firmware V220 (See Technical Note 252)
2) In SD software V370+, load the session and open the Snapshot panel.
3) Make a snapshot (to save all routing, input gains and other rack parameters) and ensure that the Recall Scope can recall all of this
information.
To do this both Global and Recall Scopes should have Input and Output channels and Input and Output Devices ticked for all relevant
input and output routes.
4) Open the Setup/Audio IO panel on the Master screen
5) Select the Opto ports (usually ports 5 and 6 which will be set as SD Racks) and set them to be DiGiRacks, and set Optocore ID if
required.
Note: In Optocore V220, racks can only have Optocore IDs in the range of 30 to 33 and therefore if your SD Racks had V221
Optocore IDs outside of the range from 17 to 20, they will need to be changed.
The Optocore IDs will the following equivalents:
V221 >> V220
ID 1.11 = ID 1.2A (Not valid in V220)
ID 1.12 = ID 1.2B (Not valid in V220)
ID 1.13 = ID 1.2C (Not valid in V220)
ID 1.14 = ID 1.2D (Not valid in V220)
ID 1.15 = ID 1.2E (Not valid in V220)
ID 1.16 = ID 1.2F (Not valid in V220)
ID 1.17 = ID 1.30
ID 1.18 = ID 1.31
ID 1.19 = ID 1.32
ID 1.20 = ID 1.33
ID 1.21 = ID 1.34 (Not valid in V220)
ID 1.22 = ID 1.35 (Not valid in V220)
ID 1.23 = ID 1.36 (Not valid in V220)
ID 1 24 = ID 1.37 (Not valid in V220)
6) Manually (or automatically if connected) conform the racks to match the previous hardware setup.
7) Recall the snapshot – this should reinstate all the routing lost when the SD Racks were converted to DiGiRacks.
8) Check sync is set to Optocore
9) Save session as a New File
