376 Trinix NXT — Installation and Service Manual
Section 18 — Analog Input Processing
Customizing Analog Video Processing Settings
When analog video signals are fed to the VI-33100 base board, each of the
16 inputs can be adjusted independently. The adjustments are made using
a terminal connection to the board.
Terminal Setup
1.
Connect a straight-through RS-232 serial cable from the VI-33100 card
front-edge 9-pin connector to the serial port of a PC with
HyperTerminal software (or equivalent).
Note An alternative to HyperTerminal is the freeware application Tera Term 3.1.3,
which can be set to a 160- column display. This allows a wide display mode
that will show the settings for all 16 inputs at once.
The location of the D connector is shown in Figure 110 on page 196 ; the
pinouts are shown in Table 97 .
CAUTION The Trinix system should not be operated with the front door open for
extended periods. Therefore the configuration cable should be disconnected
from the VI-33100 board when not in use and the door closed.
Table 97. VI-33100 Card-edge Connector Pinouts.
2.
Launch the terminal application (for example, HyperTerminal) on the
PC.
3. Set the terminal protocol to: 115200 baud, 8 data bits, 1 stop bit, no
parity bit, and no flow control.
A terminal window and a blinking cursor should appear.
4. Press ENTER.
