Section 11 — 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 114.

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 114. 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.
