Q: How do I calculate the total amount of power needed for all my DBK options?
A: You can calculate your power needs with the tables in Power Management, in the DBK Basics section
located near the front of this manual.
Q: The CA-134 cable does not work with my Daq PC-Card. Why not?
A: Daq PC-Cards Daq/112B and Daq/216B that have a serial number equal to or greater than S/N 151044
use cable CA-134. This cable’s latching connector does not work with the older PC-cards.
Daq PC-Cards Daq/112B and Daq/216B that have a serial number preceding 151044 require cable
CA-134Q.
Q: I cannot read signals with the DBK12 or DBK13. What could be wrong?
A: To measure single-ended signals with the DBK12 and DBK13:
1) the JP3 jumper on those boards must be set to SE (Single Ended)
2) the signal must be connected to the analog input High terminal and Common.
When measuring SE signals, the Low input is ignored.
To measure differential signals with the DBK12 and DBK13:
1) the JP3 jumper on those boards must be set to DIFF (Differential)
2) the signals must be connected to the High, Low, and Common input terminals.
If only 2 wires exist for your signal, connect them to the High and Low inputs and install a 1K ohm
resistor between the Low and Common [in the area between the terminal strips and the electronics] on
the DBK12 or DBK13. The place to install the resistor is labeled by channel number and is designated
by the letter "L." The letter "H" designates where to install a resistor between the high and common
terminals if balanced inputs are desired.
Note: Cards are presently manufactured with 100K ohm resistors installed in the "L" locations.
Q: My DIP switch settings appear to be giving my DBK card an incorrect address.
A: There have been a few instances in which a DBK modification included replacing one type of DIP
switch with another; for example, replacing a slide-type switch with a rocker-type switch or a toggle-
type switch. Although the actual setting of “0” and “1” values remains unchanged for configuring an
address, using a “toggle-Type” switch diagram for a “Slide-switch” results in what looks like an
opposite setting, i.e., 0-0-0-0 would look like 1-1-1-1 if the diagram was not replaced.
The following example may help you determine if you have a “0 / 1” DIP switch reversal:
Example:
If you have a 4 micro-switch DIP switch, an address of zero would require 0-0-0-0. Thus, regardless
of what your diagram may look like, the following holds true:
For a slide-type switch… the slides would all be toward “0.”
For a toggle-type switch… the depressed part of the switch would be at “0.”
For a rocker-type switch … the rocker-arm (like a standard light switch) would be toward the “0.”
Please contact the factory if you believe your DIP switch documentation is incorrect.
