Pull-up/down configuration (P3 jumpers)

Use the P3 jumpers to set the digital bits for pull-up (+5 V) or pull down (0 V) when the PCIe-DAS1602/16 is
powered on and reset. Ports A, B, CH, and CL are factory configured for pull-up.
These jumpers establish either a high (pull-up) or low (pull-down) logic level at each of the eight DIO lines on
ports A and B, and at each of the four DIO lines on ports CL and CH. The default pull-up configuration for all
ports is shown in Figure 10.

Installing the hardware

Install the software before you install your device
The driver needed to run the PCIe-DAS1602/16 is installed when you install the software. Therefore, you need
to install the software before you install the hardware.
The PCIe-DAS1602/16 is susceptible to radiated emissions
The PCIe-DAS1602/16 is susceptible to radiated emissions from other devices in the chassis such as video
adapters or other PCI/PCIe devices in adjacent PCI/PCIe slots. This can result in AI input noise levels that are
out of specification and is noted in the product electrical specification.
After you configure the board switches and jumpers (if any), install the PCIe-DAS1602/16 into your computer.
To install your board, follow the steps below:
1. Power off and unplug the computer, and remove the cover to expose the expansion slots.
2. Touch any metal part of the computer to discharge static electricity. Static electricity can damage the board.
3. Insert the PCIe-DAS1602/16 into an unused x1 PCIe expansion slot.
The PCIe-DAS1602/16 is designed to install into an x1 slot. However, you can also install the board into an
unused x4, x8, or x16 PCIe slot.
Caution! Make sure that you install the board into a PCIe slot. Installing the PCIe-DAS1602/16 into a
non-PCIe slot can damage both the board and the computer's motherboard.
4. Close your computer and turn it on.
A dialog box opens as the system loads, indicating that new hardware has been detected. The information
file for this board should have already been loaded onto your PC when you installed the software CD
supplied with your board, and should be detected automatically by Windows. If you have not installed this
software, cancel the dialog, install the software, and restart your computer.
5. Run InstaCal to test your installation and to configure the board. Refer to the Quick Start Guide that came
with your board for information on how to initially set up InstaCal.
Allow your computer to warm up for at least 15 minutes before acquiring data. The high speed components
used on the board generate heat, and it takes this amount of time for a board to reach steady state if it has been
powered off for a significant amount of time.
