Overview
  MOXA C502 Dual-Port Sync Board is truly a perfect solution for complex and versatile high-speed synchronous communication applications, such as X.25, Frame Relay, SS7, and others. Programmers simply need to make use of Moxa's easy-to-use Sync API functions to develop their own applications. And then together with the board's cutting-edge hardware components, C502 will be ready for any synchronous application, such as ATM, Satellite, or Kiosk connectivity.

The HDLC driver provides complete HDLC layer 2 data communications control conforming to CCITT, ITU, and industry standards for layer 2 protocols, including frame formatting, bit stuffing, and error detection. To further aid synchronous developers, the C502 uses a simplified configuration and the most straightforward Sync API functions. Programming languages C/C++, Delphi, and Visual Basic are all supported.

An onboard RISC CPU, combined with dual-ported memory,, effectively reduces the burden of the server CPU, bringing overall performance up to 8 Mbps on each port. This is far beyond T1/E1. The renowned Hitachi SCA (Serial Communication Adapter) is used to convert parallel data to serial data, allowing communication with other devices. Furthermore, both synchronous ports are supported with two independent full-duplex transceivers. A FIFO transmit-and-receive buffer and a four-channel DMAC (Direct Memory Access Controller) work together to enable high-speed transfer between SCA and memory.
