RS-485 as RTS enable or RTS block mode transfer. One of the unique features of the OMG-ULTRA-485-PCI is the ability to be RS-485 compatible without the need for special software or drivers. This ability is especially useful in Windows and OS/2 environments where the lower level I/O control is abstracted from the application program. -

Switch SW1 allows customization of this interface to specific requirements. Each switch position corresponds to a specific portion of the interface. If multiple OMG-ULTRA-485-PCI adapters are configured in an RS-485 network, only the boards on each end should have switches T, P & P ON. Refer to the following table for each position’s operation:... -

No two adapters can occupy the same I/O address. 3. Make sure the OMG-ULTRA-485-PCI adapter is using a unique IRQ. While the 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. -
