EOL - Serial Communication, RS422/485 Full Duplex
Product phased out. Please call systerra for replacement options.
|
These modules provide an asynchronous serial communication interface for your system. They have four asynchronous, full-duplex RS422B serial ports. Since the transceivers are compatible with the RS485 standard, you can also use a full-duplex RS485 interface for multiple driver support. However, for true halfduplex RS485 operation, use the IP502.
Software-con guration quickly sets the baud rate, character-size, stop bits, and parity.
For more e cient data processing, each serial port is equipped with 16, 64 or 128-character FIFO bu ers on the transmit and receive lines.
Features
- Four asynchronous, full-duplex RS422B serial ports (full-duplex RS485 )
- 16-, 64-, or 128-byte FIFO bu ers
- Programmable baud rate (up to 512Kbps). (Consult systerra for custom rates up to 1Mbps)
- Individually controlled interrupts (unique vectors for each port)
- Handshake control signals (RTS, CTS) for each channel
- Extended temperature option (-40...+85°C)
- Industry-standard 16C550 family UART includes software-compatible 16C450 mode
- Failsafe receivers guarantee a high output state when the inputs are left open or fl oating.
- Internal diagnostics help detect faults.
- FIFO buff ers minimize CPU interaction for improved system performance.
