The topics covered are the external user supplied power supply, the output drivers types, the input circuit and the watch dog timer. Power Supply. ____________ _ Those cards that have opto isolated outputs require an external power input to drive the isolators and the output driver chips.
OPTO DIO Reference Read This First. If an unregulated power supply is used ensure that it is rectified and has sufficient smoothing to kept it above the absolute minimum of 17 volts. Figure 1-2. Unregulated Power Supply. _________________________________ _ Unsuitable power supplies are those that provide only half wave rectification and those that are unsmoothed. Both these types fall below the minimum +17 Volts necessary to allow the on board regulation to work. Figure 1-3. Useless Power Supply.
Read This First. OPTO DIO Reference Which type of chip is fitted on the opto card is determined by the part number used to order the card. The cards are supplied with the SOURCE drivers UDN2984 fitted as standard, unless the user specified SINK at the time of ordering. The card can be easily changed between sink and source specification by exchanging certain chips and setting a pair of jumpers.

OPTO DIO Reference Read This First. Source Driver Output Logical Levels. ________________________________ _ The source cards are supplied with non inverting buffer chips, 74LS541, so that a logical one written to the output register drives the output high and a logical zero written to the output port drives the output low. Thus in this normal mode of operation the voltage level of the output line follows the logic level in the output register.
Read This First. OPTO DIO Reference from a bit pattern written to the output port the 74LS541 chips would have to be replaced by the inverting 74LS540 chips. Remove the socketed 10k resistor networks. Figure 1-8. Sink Driver Output Port Schematic. _________________________________________ Figure 1-9. Sink Driver Output Connections.
OPTO DIO Reference Read This First. The sink driver output schematic is shown in Figure 1-8. Typical output connections are shown in Figure 1-9. Note only the pull down scheme works with sink drivers. The sink drivers can only pull down the output lines. Sink Driver Output Logical Levels.

The input port lines are reverse connection protected and current limited. Input voltages of 0.
Read This First. OPTO DIO Reference interrupt or reset signal is generated on timeout. Reading the watchdog register refreshes the timer, postponing timeout for 50 milliseconds. When the watch dog times out an timer expired output signal is set. On those cards that provide opto isolated outputs the watchdog timer expired output, in place of Port A line bit 0, is available on the 50 way edge connector. The watch dog timer expired output is jumper selectable to one of four options.
OPTO DIO Reference Read This First. Watch Dog Enable Register. ________________________ _ The watch dog enable register is an 8 bit read write register. Writing the bits enables, gates, various signals onto the PC expansion bus IRQ or RESET line. Thus allowing an interrupt or reset to be generated in the PC. On power up all the bits are cleared to zero. IE No signals are gated through to the PC bus. The bit map of the Watch Dog register is given below.
Read This First. OPTO DIO Reference not refresh the timeout. It is necessary to continuously perform a read of the watch dog register at least 20 times a second. The watch dog timer may be refreshed more frequently than this, in fact, as often as the user sees fit. From the end of the last refresh a 50 millisecond period may elapse before the watch dog times out.
OPTO DIO Reference Read This First. Connector Cross Reference. ________________________ Figure 1-14 is a cross reference of the 50 IDC connector to 50 way Female D connector pinouts. Though it may seem like an arbitrary mapping it is the most logical available as can be seen from an examination of the pcb tracks.

OPTO DIO Reference Opto IN24 Volt Free Contact Whetting Voltage. _______________________________ _ An on card isolated power supply provides 12 volts at 2 Watts as a whetting voltage source for volt free contacts. This isolated 12 Volt source, with it isolated ground, can be drawn out through the edge connector on IDC pins 49 and 50, 50D pins 17 and 50, when the EXPOWER jumpers are set correctly. Figure 6-6. Expower Jumpers.
Opto IN24 OPTO DIO Reference contacts, do not necessarily have their own power source. So a switch by itself connected to the Opto IN24 card will not drive the input circuitry no matter if it is open or closed. When the ISO+12 volts is taken from the IN24 card, passed through the switch and then back to the input port pin a current can flow when the switch is closed. The current is limited by the 3k3 Ohm resistor on board the IN24 and so no more than 12 Volts/3300 Ohms = 3.6 milli amps is drawn.

Installation OPTO DIO Reference CHAPTER 7 INSTALLATION. Installing The Opto Board In The Computer. ______________________________________ _ ______ Always turn the computer OFF before installing or NOTE: removing any interface board..!!! After having made sure that the i/o address is correctly set, now is the time to insert the Opto board into the i/o connector slots in the computer. STEP 1 Before the Opto board can be installed the power to the PC MUST be switched OFF! Figure 7-1.
OPTO DIO Reference Installation Figure 7-3. Removing Blanking Cover. _________________________________ STEP 4 Choose an empty expansion slot. The Opto card will fit either a full length or a short slot, a 8 bit PC type slot or a 16 bit AT type slot. In general it is wise to leave the larger slots free for those boards that insist on greater room. Remove the blanking cover protecting the slot on the PC back panel. KEEP the blanking cover screw safely for later. Figure 7-4. Inserting The Opto Card.
Installation OPTO DIO Reference STEP 7 Now replace the system units cover by carefully sliding it down and over the system unit. Replace the cover screws. STEP 8 After attaching all the monitor and keyboard cables, power up the PC. Do not forget the mains power cable! The PC should power on in the normal way. _________ Problems! If the system fails to power up check the following. i.) Ensure that the Opto card is installed correctly. ii.) Ensure that other cards in the PC have not been upset. iii.
