Sealevel Systems DIO-16.PCI Page 2 Technical Description Technical Description The DIO-16.PCI provides two parallel input/output (I/O) ports. The ports are organized as ports A, B, C, and D. Port A is an input port interfaced to optically-isolated inputs, while port C is the reed relay output port. Features • 8 SPST relays • 1 eight bit optically isolated input port • DB-37 Male connector • Highly reliable 10 VA DIP reed relays utilized • Multiple adapters can reside in same computer • PCI 2.1 Bus compatible Input Port Port A is 8 bit input port connected to optically isolated input sensors. Each sensor can be used to interface a voltage input and then sense whether the voltage is on or off. Each sensor is isolated (with respect to a common ground) from every other sensor, and also isolated with respect to the host PC ground. This means that signals such as low- level AC line voltage, motor servo voltage, and control relay signals can be ‘sensed’, or read by the PC, without the risk of damage due to ground loops or ground faults. Each sensor input pair has a current limiting resistor that is used to limit the input current to the opto-isolator. The opto-isolator has two ‘back-to-back’ diodes internally. This allows AC or DC signals to be sensed, regardless of polarity. When the applied voltage is high enough to cause the LED in the opto-isolator to turn-on, the output of the opto-isolator goes low (0 volts) and the signal is read as a low logic level (binary 0) by the PC. When the input signal is too low to turn on the opto-isolator, the output goes high and the port bit is read by the PC as a high logic level (binary 1). The input impedance of each isolated input is approximately 560 ohms (factory default). The opto-isolator requires approximately 3 mA to turn on. The maximum input current is 60 mA. Two things to consider when selecting the input resistor: 1. The first is turn on voltage for the circuit to sense. 2. The maximum input voltage. Maximum input voltage must not provide too much power to the input resistor, and must also not overdrive the opto-isolator input current specification. The following formulas apply: Turn on current: 3 mA Isolator diode drop: 1.1 V Resistor power Max: .25 W Turn on Voltage = diode drop + (turn on current) x (resistance) Or: 1.1 + (.003) x R Maximum voltage = square root of (.25 (resistor value)) Sealevel Systems DIO-16.PCI Page 3 Technical Description The following table shows four common input resistors and the ranges associated with each. Input Resistor Min Turn-On Max Input Max Current (Ohms) (Volts) (Volts) (mA) 220 1.76 7 27 560* 2.8 12 20 1K 4.1 16 15 2.2K 7.7 24 10 *Factory default Increasing the input resistor accordingly can increase the maximum input voltage. Because socketed DIP resistor networks are utilized, they can easily be replaced with a different value. This can be done at the factory, if necessary. The input circuits are not intended for monitoring 120-volt AC circuits. Input Port Pin Assignments Port A Bit P1 0 2,20 1 3,21 2 4,22 3 5,23 4 6,24 5 7,25 6 8,26 7 9,27 Output Port Reed relays provide very high quality, long life, low current (10 Watt maximum), dry contact switch closures. Reed relays are not suited for high current applications, and can be destroyed by inductive load switching, where a spark occurs across the contacts internally. The relays are normally open, and close when energized. Writing a ‘1’ to the proper port bit can individually energize each relay.

R = Read R/W = Read or Write Function Available Port Address Hex Port Type R A Base+0 Input Port (Opto Input) B Base+1 Not Assigned R/W C Base+2 Output Port (Reed Relays) D Base+3 Not Assigned FINDPCI.EXE is a utility used in the DOS environment to identify resources that have been assigned to the adapter by the BIOS. It is found on the supplied Sealevel Software CD in the \software\seaio\Other\DOS directory. It will display resources for each detected Sealevel Systems card in the system. These settings are also stored in the file PCI.INI, located in the same directory as FINDPCI.EXE. Each system motherboard organizes its physical PCI slots according to the current PCI specification. There is not a fixed order or number of slots for each motherboard. To determine which resources correspond to which PCI card, you may want to add the cards one at a time and run FINDPCI.EXE after each card is added. Each PCI slot will have a corresponding BUS, DEVICE, and FUNCTION number. These numbers uniquely identify that slot when running these DOS utilities. Note the slot data for each card that you install. Reading the Inputs The inputs are active Low. If no voltage is applied across one of the differential inputs it returns a one on that bit. If an AC or DC voltage is applied it returns a zero on that bit. Reading the Outputs The relay ports return the ones complement of the value that is currently being used to drive the relays. Writing the Outputs: The output ports are the only ports that can be written. The relays on a standard DIO-32.PCI are normally open. To close a relay a one must be written to the appropriate bit.

Using this software and following these simple steps can eliminate most common problems without the need to call Technical Support. 1. Identify all I/O adapters currently installed in your system. This includes your on-board serial ports, controller cards, sound cards etc. The I/O addresses used by these adapters, as well as the IRQ (if any) should be identified. 2. Configure your Sealevel Systems adapter so that there is no conflict with currently installed adapters. No two adapters can occupy the same I/O address. 3. Make sure the Sealevel Systems adapter is using a unique IRQ. While the Sealevel Systems adapter does allow the sharing of IRQs, many other adapters (i.e. SCSI adapters & on-board serial ports) do not. The IRQ is typically selected by the BIOS or Operating system. Some BIOS setup software will allow changing the IRQ, but others do not. Another method of changing assigned resources is to try changing PCI slots. This will typically cause the BIOS or OS to reassign the resources. 4. Make sure the Sealevel Systems adapter is securely installed in a motherboard slot.
