Grass Valley VM 3000 System Controllers v.7.4 - Manual (Page 87)

Hardware Installation
2−15 VM 3000 Installation and Operating Manual
Up to 20 chassis can be connected in one MIDI loop.
Note 1: some Triton switchers have front−panel controls. to be shown on Jupiter control panels. These controls
will operate normally when the router is connected to a Jupiter system but Jupiter 6.0 and after software is required
in order for Triton status to be indicated on Jupiter panels.
Note 2: all RS−232/422 connections should be complete and all MIDI bus loop connections should be made and
terminated at the originating device before applying power to the Triton router.
In order for a Triton analog video router to switch on Vertical Interval as set in the Switcher Description Table, rear−panel
DIP 7 must be DOWN and a sync reference signal must be connected to Input No. 1. The reference signal must be composite
video, 1 Vpp, 300 mV sync, 75 ohms. For more information, refer to the Triton manual.

Software Configuration
The VM connected to the Triton router must be configured using the Network Description table (page 5−22) and Serial Proto-
col table (page 5−25).
Triton configuration is similar to that for other routers, beginning with the Switcher Description table (page 5−31). From that
point, switcher inputs, outputs, a CP Level Set, and CP input/Output Sets must be defined.
