C502 Dual-Port Sync Board |
|
|
Dual-Port High Speed Synchronous Board |
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. |
