Introduction Introduction Overview The DIO-16 provides 8 reed relays that can latch power, data or other electronic signals for control applications and 8 optically isolated inputs to allow monitoring of off board switch closures, relays or for any other general purpose monitoring needs. The DIO-16 is simple to operate. By writing instruction bytes to the I/O port addresses, the reed relays are energized or de-energized. Inputs are just as simply read from their data ports. What’s Included The DIO-16 is shipped with the following items. If any of these items are missing or damaged, contact the supplier. • DIO-16 Interface Adapter • Sealevel SeaIO Software CD Factory Default Settings The DIO-16 factory default settings are as follows: Base Address IRQ 300 5 To install the DIO-16 using factory default settings, refer to Installation on page 4. For your reference, record installed DIO-16 settings below: Base Address IRQ Sealevel Systems DIO-16 Page 1 Card Setup Card Setup The DIO-16 contains several jumper straps for each port which must be set for proper operation. Address Selection The DIO-16 occupies 4 consecutive I/O locations. The DIP-switch (SW1) 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 table shows several examples that usually do not cause a conflict. Address Binary Switch Settings 1 2 3 4 5 6 7 8 100-104 01 0000 00xx Off On On On On On On On 104-108 01 0000 01xx Off On On On On On On Off 200-204 10 0000 00xx On Off On On On On On On 280-283 10 1000 00xx Off On Off On On On On On 284-287 10 1000 01xx Off On Off On Off On On Off 2EC-2EF 10 1110 11xx Off On Off Off Off On Off Off 300-303 11 0000 00xx Off Off On On On On On On 320-323 11 0010 00xx Off Off On On Off On On On 388-38B 11 1000 10xx Off Off Off On On On Off On 3A0-3A3 11 1010 00xx Off Off Off On Off On On On 3A4-3A7 11 1010 01xx Off Off Off On Off On On Off Figure 1 - Address Selection Table 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 300 is selected as the base address. Address 300 in binary is XX 11 0000 00XX where X = a non-selectable address bit and address bit A9 is always a 1.

Sealevel Systems DIO-16 Page 5 Technical Description Technical Description The DIO-16 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. Assuming an I/O address of 300 Hex the following table shows the Port Addresses. Note: Ports B and Port D are decoded but not used. Base Address Hex Decimal Mode Port A Address 300 768 Input Port (Opto-Isolator Input) Port B Address 301 769 Not Used Port C Address 302 770 Output Port (Reed Relays) Port D Address 303 771 Not Used Features • Selectable I/O port addressing from 100H - 3FFH • 1 set SPST relays with each set having 8 relays • 1 eight bit input port • DB-37 female connector • Highly reliable 10 VA DIP reed relays utilized • 8 bit slot connector • Multiple adapters can reside in same computer • All address, data and control signals are TTL compatible Input Ports 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 which 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. The first is turn on voltage for the circuit to sense, and second is 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 Sealevel Systems DIO-16 Page 6 Technical Description Maximum voltage = square root of (.25 (resistor value)) 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 32 560 2.8 12 22 1K 4.1. 16 16 2.2K 7.7 24 11 The maximum input voltage can be increased by increasing the input resistor accordingly. 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. In addition to being too high a voltage for the circuits, it is dangerous to have that high a voltage on the card.

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. Each relay can be individually energized by writing a ‘1’ to the proper port bit.

The SeaIO driver and API have been included to provide control over the hardware in Windows and Linux environments. Complete documentation of the API can be found in its accompanying help file. Direct Hardware Control In systems where the users program has direct access to the hardware (DOS) the table below gives the mapping and functions which the DIO-16 provides, a base address of 300 was used. If a different base address is used then the port addresses are calculated as shown in the table. 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 (of sufficient magnitude, covered above) is applied it returns a zero on that bit. Reading the Outputs (relays) The relay ports return the ones complement of the value that is currently being used to drive the relays. When using the API the value is returned not the complement of the value. Writing the Outputs (relays) The output ports are the only ports that can be written. The relays on a standard DIO-16 are normally open. To close a relay a one must be written to the appropriate bit.
