Grass Valley VM 3000 System Controllers v.7.4 - Manual (Page 720)

L−8 VM 3000 Installation and Operating Manual
Y LINE TABLE − VTR CONTROLLER/TRIBUTARY SELECTION
Note: These instructions assume that the installer has read “Data Matrix Installation” in Section 3 of the Venus
Routing Switcher System Technical Manual.
Some VTRs can act as controllers or tributaries. These can be connected with a “Y” cable to two Venus ports— one for use
when the VTR is a controller, the other when the VTR is used as a tributary (see Figure L−14). If the VTR is operated only as a
controller, or only as a tributary, then a “Y” cable will not be needed; the cable can instead be one of those shown on page L−4.
The following tables correspond to the system shown in Figure L−14. The basic rules for these tables have already been de-
scribed (starting on page L−3).

The Y Line table informs the matrix board (VM 3000 Control Processor) of a level, input, and output that have a Y line
installed. Notice that each Y line requires two entries, and that the “crossover” ports (the “M” ports) are listed as inputs on
the forward level and outputs on the reverse level:
