PCI RS-422, RS-485 Serial Interface
|
SEALEVEL 7204
Ultra-COMM 2.422 |
|
| |
The 7203 PCI serial interface provides two optically isolated 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 7203 utilizes 16C850 UARTs to provide 128-byte Tx/Rx FIFOs for maximum reliability in data intensive applications. Ordering options allow the choice of UARTs for custom baud rates and 9-bit protocols. Sealevel's SeaCOM software utilities make installation and operation easy.
