1.1 SOFTWARE

Before you open your computer and install the board, install and run InstaCal™, the
installation, calibration and test utility included with your board. InstaCal™ will guide
you through switch and jumper settings for your board. Detailed information
regarding these settings can be found below. Refer to the Software Installation manual
for InstaCal™ installation instructions.

1.2 HARDWARE

The PC104-DAS16Jr/12 has one bank of switches, two single function switches and
one jumper block which must be set before installation of the board inside your
computer (Figure 1-1). The PC104-DAS16Jr/16 has one additional switch for
selecting unipolar or bipolar ranges (Figure 1-2).

1.3 BASE ADDRESS

The base address switches are set at the factory
to address 300h (768 decimal) as shown on
Figure 1-3. Unless there is already a board in
your system using this address, leave the
switches as they are set at the factory.

In the example shown in Figure 1-3, the
PC104-DAS16Jr/xx is set for base address
300h. See Figures 1-1 and 1-2 above for switch
orientations and locations on the boards.

1.4 DMA LEVEL SELECT

If using an XT PC there are only two DMA levels available and level 3 is probably
used by the hard disk controller. Set the DMA level switch to the level 1 position
(Figure 1-4). See Figure 1-1 or 1-2 for switch location.

If you have an AT or 386 type
computer the hard disk controller is
not at level 1 or 3 so either level may
be used.

There are other boards that use DMA
levels. Some network boards do and
so do some IEEE-488 interface
boards. If you have other boards in
your computer with DMA level
switches on them, make sure there are
no conflicts

Figure 1-4. DMA Level Select Switch

1.5 1 OR 10 MHZ CRYSTAL OSCILLATOR JUMPER

The 1/10 (1 or 10) MHz XTAL jumper selects the frequency of the source applied to
the on-board pacer. This pacer (counter 2) is used to pace the A/D start conversion
trigger (Figure 1-5). See Figure 1-1 or 1-2 for jumper location.

This jumper is on the board because the original DAS-16, designed in 1984, had a 1
MHz crystal. When MetraByte redesigned the DAS-16 and added the faster 10 MHz
crystal, a jumper was provided to maintain compatibility with older software.

The PC104-DAS16Jr/xx has the
jumper because the DAS-16 has the
jumper and some software requires
the jumper to be in the 1 MHz
position. However, some software
requires the 10 MHz position.

The PC104-DAS16Jr/xx is shipped

with the jumper in the 1 MHz
position. InstaCal allows you to

specify 1 or 10 MHz position in the
setup. See Figure 1-1 or 1-2 for
jumper location and orientation.

Note the difference in orientation in
Figures 1-1, 1-2, and 1-5. Figure 1-5. Frequency Select Jumpers

Older software may require the 1 MHz setting for this jumper. Use the 10MHz setting
for any new software development to get better resolution setting pacer frequencies.

1.6 8/16 CHANNEL SELECT

The PC104-DAS16Jr/xx can be
configured for eight differential
or 16 single-ended inputs. Using
differential inputs allows up to 10
volts of common mode (ground
loop) rejection and can be more
noise immune.

The PC104-DAS16Jr/xx comes
from the factory with the select
switch set for 8 differential inputs
as shown in Figure 1-6. Set it for
the number of inputs you desire.
See Figure 1-1 or 1-2 for switch
location. Figure 1-6. Channel Quantity Select Switch

1.7 INSTALLING THE BOARD

Having configured the board’s switches and jumpers, it is now time to add the board
to the PC104 bus in the PC.

1. Turn the power off.

2. Remove any covers, etc. so you can get access to the PC104 bus. Please be
careful not to dislodge any of the cables installed on the boards in your
computer.

3. Remove the retaining screws on the topmost PC104 card installed. Replace
these screws with the threaded standoffs provided.

4. Push the PC104-DAS16Jr/xx board firmly down into the PC104 bus
connector. Secure it in place with the screws removed in the previous step.

2 SIGNAL CONNECTIONS

2.1 CONNECTOR DIAGRAM

The PC104-DAS16Jr/xx analog connector is a 40-pin in-line header connector (Figure
2-1). This connector accepts the C40FF-# cable which mates with the CIO-MINI40
screw terminal board.

side with the components facing up.

If compatibility with the CIO-DAS16 series connector is desired, you can convert to a
compatible 37D connector using the C40-37F-# or C40-37M-# cables. If the BP40-37
Adapter Cable is used, is accessible from the rear of the PC through the expansion
back plate (Figures 2-2 and 2-3). Using these adapters, the signals available are
identical to the DAS-16 (with the exception of the missing D/A signals). An additional
signal, SS&H OUT, can be accessed at pin 26.
