Grass Valley Aurora Ingest v.6.5.2 - Manual (Page 46)

About RS-422 switching
If RS-422 switching is not enabled, you do not have to select the levels because Aurora
Ingest switches all levels when switching the router for server port switching and VTR
Ingest monitoring switching. Conversely, if RS-422 switching is enabled, Aurora
Ingest switches the router differently.
• Each VTR source has four levels.
• Feed sources have two (if they use VITC) or three (if they use LTC) levels.
• K2 destinations have the HD-SDI, AES and LTC levels (we know for certain VTRs
use LTC).
• VTR Ingest video capture destinations have the HD-SDI level (and AES if speakers
are connected).
• VTR Ingest com ports destinations have the RS-422 level.
