Low-profile PCI RS-232 synchronous serial adapter designed for secure and stable communication up to 128 Kbps. Ideal for legacy and protocol-driven applications..
The 5103 ACB-232.LPCI provides one RS-232 synchronous serial port for low-profile PCI slots, supporting secure and reliable data exchange in industrial and legacy system environments. Leveraging the Z85230 Enhanced Serial Communications Controller (ESCC), this adapter is purpose-built for mission-critical communications.
With support for popular synchronous protocols such as HDLC and SDLC, and the ability to configure for Monosync, Bisync, or raw data transfer, this card ensures adaptability for custom applications. Full modem signal support ensures compatibility with a wide range of legacy devices. It’s ideal for use in applications like secure data transfer, banking, or defense where protocol precision and reliability are critical.
Sealevel’s SeaMAC software stack simplifies driver integration and application development for synchronous communication on modern Windows platforms. The 5103 is designed for MD1 Low Profile PCI slots; for standard height systems, order model 5103S.
