SEA-7402

SEALEVEL 7402 Ultra COMM+422 PCI
The 7402 PCI interface provides four serial ports, each individually configurable for 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 7402 utilizes 16C550 UARTs that provide 16-byte Tx/Rx FIFOs and ships with a 36" cable that terminates to four DB-9M connectors. Ordering options allow the choice of UARTs with larger FIFOs, support custom baud rates, and 9-bit protocols. The 7402-SE utilizes 16C850 UARTs to provide 128-byte Tx/Rx FIFOs for maximum reliability in data intensive applications. For custom baud rates and 9-bit protocols, order the 7402-SN which utilizes 16C950 UARTs. If your application requires RoHS compliance, order the 7402-RoHS.
