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.
Aurora Ingest switches:
• level 1, 2 and 3 for source-to-server port switching.
• level 1 (and 2) for VTR Ingest monitoring switching.
• level 4 for VTR to VTR Ingest Com Port switching.
