Hardware Setup
DBK11A Connections
The DBK11A connects to a P1, P2, or P3 DB37 connector via a CA-37-x cable. The card has screw-
terminal blocks for easy access to analog inputs and outputs. Each screw-terminal has a number
that corresponds to a pin number on the DB37 connector.
The DBK11A prototyping area, see figure, contains standard 0.1” hole spacing for the optional installation
of
user-customized circuitry.
BNC connectors can be soldered to the board at footprints labeled: CN0, CN1, CN2, and CN3. These will
have connectivity to J6 and J12, as indicated in the figure. The J6 and J12 terminals can be wired to the
other screw terminals to provide BNC connection for designated P1 pins.
DBK11A Board Layout
Reference Notes :
Refer to chapter 2, System Connections and Pinouts, to verify the pin designations for P1, P2, or P3,
as applicable. The DBK11A screw-terminals are labeled 1 through 37. These numbers correspond
one-to-one with specific DB37 pins for P1, P2, and P3.
To make wire connections to the card’s terminal blocks :
1. Refer to the applicable pinout (P1, P2, or P3) in chapter 2, System Connections and Pinouts .
2. Using 14 to 26 gage signal wire, make the appropriate connections to the DBK11A terminal blocks.
The screw-terminal numbers 1 through 37 correspond directly with the P1, P2, or P3 pins, depending
on which DB37 connector applies.
3. Once all connections have been made, secure all wires at the end of the DBK11A board. Nylon tie
wraps (not included) work well for this purpose.
