Moxa
MC502 Dual-Port Sync Board is a perfect solution for complex and versatile high-speed
synchronous communication applications, such as X.25, Frame Relay, SS7, and
others. ozpv
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 MC502 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.
