Product short description:
- 8 asynchronous full duplex EIA/TIA-422B serial ports (supports EIA-485)
- 64-byte FIFO buffers
- Interrupt support
- Programmable baud rate (up to 1.8432Mbps)
These modules provide eight asynchronous serial communication ports from a single PMC Socket. Software-configuration helps you quickly set baud rates, character-sizes, stop bits, and parity.
For more efficient data processing, each serial port is equipped with 64-character FIFO buffers on the transmit and receive lines.
The data ports generate individually controlled transmit, receive, line status, data set, and flow control interrupts. A global interrupt source register provides interrupt status indication for all eight channels to speed up interrupt parsing.
Specifications
RS422B Serial Ports
Configuration: Independent, non-isolated serial ports with a common single return connection.
Data rate: 20MB /second, maximum. Standard crystal limits data rate to 1.8432Mbps.
Max. cable length: 1200 meters (4000 feet), typical.
Character size: 5 to 8 bits, software-programmable.
Parity: Odd, even, or no parity; software-programmable.
Stop bits: 1, 1-1/2, or 2 bits; software-programmable.
Data register buffers: Double buffered or 64-byte FIFO buffered, mode selectable.
Interrupts: Receiver line status (overrun, parity, framing error, or break interrupt); receive/transmit FIFO level reached or character time-out; Xon/Xoff or special character detected.
Environmental
Operating temperature: 0 to 70°C (PMC521-64) or -40 to 85°C (PMC521-64E).
Storage temperature: -55 to 125°C.
Relative humidity: 5 to 95% non-condensing.
Power: +5V (±5%), consult factory for current specifications.
MTBF: 2,321,047 hrs at 25°C, MIL-HDBK-217F, notice 2.
PMC Compliance
Conforms to PCI Local Bus Specification, Revision 2.3 and CMC/PMC Specification, P1386.1.
4K Memory Space Required: One Base Address Register.
Signaling: 3.3V and 5V compliant.
