Analog Processing Control
The VI-33100 universal input module accepts analog as well as digital sig-
nals. Adjustments for analog sign
als include the following:
• Save/recall settings
• Mono mode
• Setup on/off
• Chroma kill
•Comb/trap filter
•AGC on/off
• Manual gain control
• ACC on/off
• Manual chroma
control
•Blank video (per
VBI line)
• Add setup (per VBI
line)
• Reserve VBI line for
data
• Horizontal timing
• Detail enhancement
• Display channel
status
• Insert Error Detec-
tion and Handling
(EDH) data
• Contrast / Y gain
• Saturation /
chroma gain
•Brightness / Y
offset
•Hue / chroma
phase
• Notch decode on/
off (VBI)
• Chroma kill (VBI)

Pre-wiring
All Trinix Routing switchers are pre-wired to the size of the frame. For
example, a 128-frame is pre-wired to 128 x 128 with all rear panels and
BNCs in place; the 256-frame is pre-wired to 256 x 256.
By convention, Routing switcher
sizes are shown as:
M x N (P x Q)
This indicates that the functional router
size is M x N and is pre-wired to (P
x Q). Symmetrical Trinix pre-wiring is only possible in multiples of 128 x
128, as that is the smallest frame size increment.
Connector Numbering
Late-model Trinix routers have video input/output connectors that begin
with “1” instead of “0.” An adhesive overlay set, which indicates connector
groups using a 0-based numbering scheme (for example, Inputs “0-31,”
Inputs “32-63,” etc.) is provided for customers who are using a 0-based
control system such as Jupiter.
