1. APPENDIX C CIRCUIT CARD SCHEMATIC cccccsssscsccssssccccccsssccccccssccccssssscscess 11 ii ANC 1008 IBM Pc XT AT Compatible Discrete Relay Card 1 0 Overview Discrete relays with C type configuration Programmable directly in BASIC Relays handle 115 VAC at 1 Amp LED display of card and relay status User selectable I O address Read back of relay output condition System reset opens all relays User snubber capacitor locations for all contacts 1 1 oo o o Providing 8 C type discrete relay contacts for general purpose application the ANC 1008 occupies a short card slot in the IBM Pc XT AT or IBM System 2 30 computer Each relay provides a normally open and normally closed output C type configuration The card occupies a short card slot in the Pc and signal output is obtained by way of a DB 25 D shell type connector Upon system power up or system reset all of the relays are initialized in a off condition The user may then set the desired relay configuration and enable the relay drivers A 9 LED display array viewable under the rear mounted DB 25 connector shows card reset and relay status The ANC 1008 uses a single user selectable I O address for its operation and the output relay configuration may be read back into the Pc The user may add capacitors across each of the normally open and normally closed contacts to attenuate noise when switching DC voltages Programming can be performed directly in
2. BASIC or by ASSEMBLY LANGUAGE The appendix included provides sample driver software which designers may use as a basis for developing their own device drivers 1 1 Card Initialization Upon power up all relays are initialized off The user may of course use the normally closed contact on any of the discrete relays so that at power up a circuit is closed rather than open Upon system power up the card s relay latch register should be loaded with the desired relay configuration and then a dummy read operation is performed to enable the relay drivers A sample initialization program is included as Appendix A of this manual The general procedure for initialization of the card is as follows 1 Setting the initial condition of the relays on the card 2 Enable the relay card for operation by doing a read of the relay status port same address as relay control port 3 Transfer control to start execution of user stored BASIC or ASSEMBLY LANGUAGE program 1 3 1 I O Port Addressing The following table details the address and function performed for I O port operation Card bit weight Hex Value Port 98 7654 3210 as Shipped Comment XX XXXX XXXX 310H 8 bit relay control port XX XXXX XXXX 310H 8 bit relay status port Note that the X s are user selected bits set on the 10 bit switch on the ANC 1008 card The user has the ability to set the card to any single I O address The output input bits are directed to the 25 pin D shell con
