The OMG-ACB Series provides the PC-based system with single/dual high-speed synchronous/ asynchronous links to instruments requiring extremely fast data flow. The RS-422 communications standard allows the OMG-ACB to communicate reliably at high speeds under harsh conditions, which makes it an ideal solution for industrial environments. Line noise, present in industrial environments, is eliminated over the RS-422 line. By utilizing RS-422, factory applications requiring long distance communications operate with high data integrity. Signals are transmitted and received via 25-pin sub-D connector(s). The OMG-ACB-II is also capable of RS-232 for applications requiring shorter distances and RS-232 compatibility.

Balanced differential drivers and receivers are utilized to provide RS-422 and RS-485 communications. Selectable interrupts (IRQ levels) increases the card’s versatility. Distances of 5000 ft in noisy industrial environments are easily accommodated with the OMG-ACB.
