The DWYEROMEGA OMG-VERSA-COMM4 is a four-port RS-232 ISA bus interface module engineered for industrial serial communication expansion. It delivers full modem control signaling across each port with configurable interrupt handling and flexible I/O addressing. The module accommodates the standard 16554 UART or optional 16654 UART, providing 16-byte FIFO buffering and per-port data rates to 460.8 kbps over distances up to 15.2 m.
