Card Setup

SW1 (Analog to Digital Current Loop Mode)

DIP-switch SW1 selects the A/D Current loop Mode. With the switch on, the channel is in a 0-20mA current

loop mode (with a 249 ohm 1% resister to ground and a 21K ohm input resistance, effective resistance is

equal to 246.1 ohms). With it off the channel is in a software selectable mode with selections of 0-5V, 0-

10V, ±5V and ±10V.

SW2 (Address and Interrupt Mode Selection)

The AIO-104+10 will occupy 16 consecutive I/O locations. The DIP-switch SW2 is used to set the base

address for these locations. Be careful when selecting the base address as some selections conflict with

existing PC ports.

The following illustration shows the correlation between the DIP-switch setting and the address bits used

to determine the base address. In the example below, address 300H is selected as the base address.

Address 300H in binary is XX 11 0000 XXXX where X = a non-selectable address bit.

Setting the switch ‘On’ or ‘Closed’ corresponds to a ‘0’ in the address, while leaving it ‘Off’ or ‘Open’

corresponds to a ‘1’.

Switch positions ‘S’ and ‘M’ on switch SW2 selects the interrupt mode for each adapter.

With the ‘S’ selected, the adapter is in a (S)hared interrupt mode, which allows more than one adapter to

access a single IRQ.

‘M’ indicates the inclusion of a 1K-ohm pull-down resistor required on one adapter when sharing interrupts.

Set the switch to ‘S’ for shared interrupt mode on all adapters sharing an IRQ. On one of the adapters sharing

an interrupt set the switches for both ‘S’ and for ‘M’. This provides the pull-down resistor circuit that makes

sharing IRQs possible. If you are using more than one compatible adapter in a bus, you should only have

one adapter set to ‘M’.

Header E1 (IRQ Selection

The AIO-104+10 has an IRQ selection jumper, which should be set prior to use, if an interrupt is required by

the application software. Consult the user manual for the application software being used to determine the

proper setting.

Headers E3 and E4 (D/A Voltage Range Selection)

Headers E3 and E4 set the D/A channel 0 and 1 output voltage range selection. This is selectable per

channel and is selected as either the 0-2.048V range or 0-4.095V range.

Header E2 (Voltage Selection)

Header E2 selects the voltage that is supplied from the card on pin 37 of the IDC40 connector J1. It is fused

at 1A and is either +5VDC or +12VDC.

0-2.048V

Software Installation

Windows Installation

Do not install the adapter in the machine until the software has been fully installed.

Only users running Windows 7 or newer should utilize these instructions for accessing and installing

the appropriate driver via Sealevel’s website. If you are utilizing an operating system prior to

Windows 7, please contact Sealevel by calling 864.843.4343 or emailing support@sealevel.com to

receive access to the legacy driver download and installation instructions.

1. Begin by locating, selecting, and installing the correct software from the Sealevel software

driver database.

2. Select the Part Number (#3810) for your adapter from the listing.

3. Select the download for the SeaIO Classic for Windows (Software: SeaIO Classic V5 - Windows

- Sealevel.) The setup file will automatically detect the operating environment and install the

proper components. Next (depending on your browser) select the ‘Run this program from its

current location’ or ‘Open’ option. Follow the information presented on the screens that follow.

During setup, the user may specify installation directories and other preferred configurations.

This program also adds entries to the system registry that are necessary for specifying the

operating parameters for each driver. An uninstall option is also available to remove SeaIO files

and registry/INI file entries from the system.

4. If installing in NT skip to ‘Windows NT Card Installation’ step 16.

5. Go to the "Add New Hardware Wizard" in the Control Panel.

6. When the Wizard asks if Windows should search for the new hardware, choose "No, I want to

select the hardware from a list."

7. Scroll through the list of categorized hardware and select ‘SeaIO Devices’. If this is the first

SeaI/O device select ‘Other Devices’ and ‘Sealevel Systems, Inc.’ instead of ‘SeaIO Devices’

8. Click "Next."

9. Select the card model and press "Next."

10. The Wizard will continue to guide through a few more informational prompts; continue to click

"Next" until it is completed.

11. The card's resource assignments may be adjusted through the Device Manager (if, for instance,

a change is needed in the I/O port address Windows assigned when the card was installed).

12. Windows software installation is complete

13. Windows NT Card Installation: After accomplishing steps 1 – 6, bring up the Control Panel and

double-click on the SeaIO Devices icon. To install a new card, click "Add Port". Repeat this

procedure for as many SeaIO cards as needed.

Physical Installation

Extreme care should be taken when installing the adapter to avoid causing damage to the connectors. After

the adapter is installed, connect the I/O cable to P1. Please note these headers are keyed so that pin 1 of

the cable matches pin 1 of the connector. Refer to Card Setup for information on setting the address before

inserting the adapter onto the stack.

1. Disconnect power to host machine.

2. Gently insert the adapter connector noting proper key orientation of the expansion connector on a

PC/104 compatible card. The adapter is keyed per the current PC/104 Specification. This will aid

in preventing the adapter from being inserted incorrectly.

3. Mounting hardware (nylon stand-offs and screws) is provided to ensure a good mechanical

connection. Retain any mounting hardware not used to allow for future expansion.

4. The cables provided are keyed and can be installed before or after the adapter is inserted in the

stack.

5. Reconnect to power source.

Technical Description

The AIO-104+8 is a PC/104 form factor adapter that provides an eight channel multiplexed; single-ended,

12-bit Analog to Digital converter and a two channel 12-bit Digital to Analog converter. The adapter also

provides 16 bits of Digital I/O, with input/output direction selectable at the bit level.

The Analog to Digital Converter is software configurable to ranges of 0-5V, 0-10V, ±5V and ±10V

conversions with 12-bit resolutions at a maximum sampling rate of 100K Samples per Second (SPS).

Additionally, each channel may be selected via a DIP-switch to measure a 0-20 mA current-loop input.

Of particular importance is the impedance of the inputs. Typically this impedance in voltage mode is 21K

unipolar mode and 16K in the bipolar mode.

If the maximum voltage is greater than ±15 volts, do not connect the board to this signal source. A

maximum voltage greater than ±15 is beyond the board’s usable common-mode range. Either adjust the

grounding system or add some type of isolated signal conditioning to make reasonable measurements.

Any voltage measured with respect to ground should not be more than ±15V as this could damage the

board and possibly the PC.

The Digital I/O bits are individually selectable at the bit level as to Input or Output.

The adapter occupies 16 consecutive I/O addresses. The following table describes each I/O bit and its

usage.
