Make sure that the IRMAtrac adapter does not have the same interrupt level as another adapter. (The Set configuration program does not indicate interrupt conflicts. You need to manually check for conflicts.) If an interrupt conflict occurs while the IRMAtrac adapter is operating, a variety of malfunctions can result."

Default: DMA Arb 04. The DMA arbitration level ranges from 0 to 14, with 0 as the highest priority and 14 as the lowest priority. If two devices want to use the DMA channel at the same time, the highest priority device wins. Each adapter in your system must have a unique arbitration level. An asterisk (*) next to your arbitration selection means there is a conflict. If there is a conflict, you must choose a new arbitration level. If you choose automatic configuration, the Set configuration program searches for an arbitration level that is not in use, starting with arbitration levels 04 through 14, then 00 through 03. If no arbitration levels are available, PIO is chosen. In most cases, you will not notice the effect of the arbitration level on IRMAtrac's performance."

Fairness determines how the IRMAtrac adapter contends for the DMA bus through its arbitration level. This field is valid only for Bus-Master DMA operation. If fairness is ON, the adapter equitably shares the channel with other DMA devices. If fairness is OFF, lower-priority DMA devices may be excluded from the bus. In most cases, however, you will not notice the effect that the fairness setting has on IRMAtrac's performance." NamedItem Prompt "Bus Release for Bus-Master DMA" choice " Delay " pos[2] = xxxxx1xxb choice " Immediate " pos[2] = xxxxx0xxb Help "Choose Delay or Immediate for bus release. Default: Delay. The bus release setting determines how quickly the IRMAtrac adapter releases the bus after another device issues a DMA bus request. This field is valid only for Bus-Master DMA operation. If bus release is Delay, the adapter can hold the bus for a maximum of 7.8 microseconds before releasing it. If bus release is Immediate, the adapter releases the bus immediately after a DMA bus request is issued. Delay offers the best performance, because the IRMAtrac adapter can hold the bus for a longer period of time without interruption. If you specify Delay, other devices' performance may degrade because they cannot access the bus as quickly. However, in most cases, you will not notice the effect that the bus release setting has on IRMAtrac's performance."
