PCI RS-232, RS-422, RS-485 Serial Interface
|
SEALEVEL 7201
Ultra COMM+2.PCI |
|
| |
The 7201 PCI serial interface provides two serial ports, each individually configurable for RS-232, RS-422, or RS-485. The board is capable of data rates to 460.8K bps and automatically handles RS-485 transmitter enable/disable. The 7201 utilizes 16C850 UARTs that provide 128-byte Tx/Rx FIFOs and is Universal Bus (3.3V or 5V) compatible. Ordering options allow the choice of UARTs with larger FIFOs, support for custom baud rates, and 9-bit protocols. Sealevel's SeaCOM software utilities make installation and operation easy.
For custom baud rates and 9-bit protocols, order the 7201-SN which utilizes 16C950 UARTs. If your application requires RoHS compliance, order the 7201-RoHS.
