Card Setup

The OMG-ULTRA-SIO contains several jumper straps that must be set for

proper operation.

Address Selection

Each port on the OMG-ULTRA-SIO occupies eight consecutive I/O locations. A

DIP-switch is used to set the base address for these locations. SW1 sets the I/O

address for port 1 and SW2 sets port 2. The following table shows the

addressing options available. If different address options are required, please

contact Technical Support about a custom PAL option.

Figure 1 - Address Selection Table

Note: Each COM: port in the system should have a unique address. Typically

COM1: - COM4: addresses are 3F8, 2F8, 3E8 and 2E8 Hex.

Refer to Appendix A for common address contentions.

Port Enable / Disable

Each port on the OMG-ULTRA-SIO can be enabled or disabled with switch

position 4 on the DIP-switch. The port is enabled with the switch ‘On’ and

disabled when ‘Off’. If any port is disabled, be sure to disable the interrupt

request for that port by removing the IRQ jumper.
