Reference Notes:

Refer to the DBK Basics section of this manual in regard to calculating system power

requirements.

Chapter 2, System Connections and Pinouts, includes pinouts for P1, P2, P3, and P4

connectors.
Refer to the pinouts that are applicable to your system, as needed.

For a quick comparison of all DBK200 Series boards, refer to the DBK200 Series Matrix.

The matrix is located just before the DBK200 section of this manual.

Refer to the DaqBoard/2000 Series and cPCI DaqBoard/2000c Series User’s Manual

(p/n 1033-0901) or the DaqBook/2000 Series User’s Manual (p/n 1103-0901) for information
pertaining to those products, as needed.

Overview

DBK210 Carrier Board for Grayhill 70M-Series Mini-Modules

The information included in this section, when combined with that found in related DBK sections, should
enable you to set up your desired configuration.

It is important to note that the DaqBoard/2000 Series boards communicate [external from the host PC]
through a 100-pin P4 connector. The P1, P2, and P3 connectors discussed in association with these boards
are subset connectors of the 100-pin P4 connector. DaqBook/2000 Series devices have both a P4
connector and a set of P1, P2, and P3 connectors on the unit. The System Connections and Pinouts chapter
includes pinouts for both types of devices, i.e., DaqBoards and DaqBooks.

DBK210 is a four-bank carrier board for optically-isolated Grayhill 70M-Series mini-modules. Each bank
supports up to eight digital I/O modules. Each bank can be independently set to input or output. The
settings are made via micro-switches on S1 (see next two figures). The Grayhill 70M-Series I/O modules
are industry standard, 5-volt logic level modules.

WARNING

Ensure that hard-wire emergency over-ride circuitry exists for all applications that
make use of dangerous switch-loads. Do not operate such switch-loads unless
emergency over-ride circuitry is present.

Note 1: DBK210 is not used with DaqBoard/2003.
Note 2: DBK210 can be used with DaqBook/200 series and Daqboard/200 series devices;

but should not be used with DaqBook/100 series or DaqBoard/100 series devices.

S1 Detail

The S1 settings for the Banks and the Local Addresses must match the associated settings
in DaqView. This is explained in the Software Setup section, which begins on page 7.

Note: S1 functionality is explained in the following three sections : External Power Watchdog (pg. 5),

Setting Module Banks to Input or Output (pg. 5), and Setting the Local Addresses (pg. 6).

DBK210 boards are typically installed in NEMA-type panels; however, they can be installed on DIN rails.
Separate mounting instructions are included with Rack Mount Kit (part no. Rack-DBK-3) and with DIN­rail Mount Kit (part no. DIN-DBK-1).

DBK210 is controlled digitally from the Daq device (DaqBook or DaqBoard) as follows:

DaqBook/200 Series Devices – control is through the 37-pin P2 digital port of the DaqBook and one of
two DBK210 P2 connectors.

DaqBoard/200 Series boards [ISA-type] - control is through the 37-pin P2 digital port of the DaqBoard
and one of the DBK210 P2 connectors.

DaqBook/2000 Series Devices – control is achieved by either of the following two methods, but not both
at once:

• Connect a CA-37-x cable to the P2 connector on the DaqBook/2000 Series device; then

connect the free end of the cable to one of the two P2 connectors on the DBK210.

• Connect a CA-195 cable to the P4 connector on the DaqBook/2000 Series device; then

connect the free end of the cable to the P4 connector on the DBK210.

DaqBoard/2000 Series boards – control is through the board’s 100-pin P4 connector. Connection of
these boards to DBK210 can be made directly or indirectly as follows:

• Direct connection can be made from a /2000 Series board’s 100-pin P4 connector to a

DBK210’s P4 connector via a CA-195 cable.

• Indirect connection can be made using one of the DBK200 Series P4-adapters that includes a

37-pin P2 connector (DBK201, DBK202, DBK203, DBK204, DBK206, DBK209, or another
DBK210). CA-37 cables are used to connect from the P2 connector of the adapter device to
the P2 of the DBK210.

A single Daq-based data acquisition system can support up to 8 DBK210 boards, providing a total of 256
channels. The following figure represents a 64 channel digital I/O system using two DBK210s.

DBK210 boards contain three DB37 connectors, as follows: two P2 connectors for daisy-chaining to other
DBK210s or to other P2-supported devices; one P1 connector for convenient access to the analog input
channels of a 2000 Series DaqBook or a 2000 Series DaqBoard.

DBK210 System in a NEMA Enclosure

In the above figure, the upper DBK210 is connected to a DaqBoard/2000 Series board that has been
installed in an industrial PC. The connection is made from the P4 connector on the installed DaqBoard to
the P4 connector on one of the two DBK210 boards. A 100-conductor CA-195 ribbon cable is used. The
two DBK210s are daisy-chained from a P2 connector on one board to a P2 connector on the other. Each
board has a P1 connector making it possible for analog expansion.
