Four asynchronous EIA-485 serial ports
16-byte FIFO buffers
Interrupt support
Programmable baud rate (up to 512Kbps)
These modules provide an asynchronous serial communication interface for your system. The IP502 has four asynchronous, half-duplex EIA-485 serial ports. It provides a cost-efficient interface to EIA-485 multi-driver networks which support up to 32 nodes. However, for full handshaking support, use the full-duplex IP501.
Software-configurati
on quickly sets the baud rate, character-size, stop bits, and parity.
For more efficient data processing, each serial port is equipped with16-character FIFO buffers on the transmit and receive lines.
Benefits
Failsafe receivers guarantee a high output state when the inputs are left open or fl oating.
Internal diagnostics help detect communication faults.
16-byte FIFO buff ers minimize CPU interaction for improved system performance.
Features
Four asynchronous, half-duplex EIA-485 serial ports
16-byte FIFO buffers
Programmable baud rate (up to 512Kbps) (Consult factory for custom rates up to 1M bps)
Individually controlled interrupts (unique vectors for each port)
Line-break and false start-bit detection
Industry-standard 16C550 family UART includes software-compatible 16C450 mode
0 to 70°C
