The 7105-DB9 PCI serial interface is designed with a DB-9 connector pinned out compatible with AC24AT and AC422AT Opto-22 ISA bus cards. This allows Optomux devices to be controlled from PCs that do not have an ISA bus expansion slot available. The 7105-DB9 is compatible with standard 5V PCI slots.

The 7105-DB9 PCI serial interface provides a single field selectable port configurable as RS-422 or RS-485 supporting asynchronous data rates up to 460.8K bps.
