Four asynchronous EIA/TIA-422B (EIA-485) serial ports
FIFO buffers (16, 64, or 128-byte)
Interrupt support
Programmable baud rate (up to 512Kbps)
These modules provide an asynchronous serial communication interface for your system. They have four asynchronous, full-duplex EIA/TIA-422B serial ports. Since the transceivers are compatible with the EIA-485 standard, you can also use a full-duplex RS-485 interface for multiple driver support. However, for true half-duplex EIA-485 operation, use the IP502.
Software-configurati
on quickly sets the baud rate, character-size, stop bits, and parity.
For more efficient data processing, each serial port is equipped with 16, 64 or 28-character FIFO buffers on the transmit and receive lines.
Benefits
Failsafe receiversguarantee ahighoutput state when the inputs are leftopenor oating.
Internaldiagnosticsh
elpdetect faults.
FIFO bu ers minimizeCPU interactionfor improved system performance.
