C502 Dual-Port Sync Board
Dual-Port High Speed Synchronous Board for Windows NT
MOXA C502 Dual-Port Sync Board for Windows NT
provides high-speed synchronous communication
solutions for X.25, Frame Relay, SS7 or other synchronous
communication programming. Cutting-edge hardware
components with handy API functions easily turn C502
into any synchronous application, such as ATM, Satellite,
or KIOSK connectivity.
The HDLC Windows NT 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 help synchronous developers, C502 brings
simplified configuration and the most straight forward Sync
API functions. C/C++, Delphi, or Visual Basic are all
supported for programmers.
Onboard RISC CPU combined with dual-port memory
effectively reduces burden of server CPU and brings
overall performance far beyond T1/E1, up to 4Mbps on
each port. Renowned Hitachi Serial Communication
Adapter(SCA), which converts parallel data to serial data
for communication with other devices, supports both
synchronous ports with two independent full-duplex
transceivers. FIFO transmit and receive buffer and a four-
channel direct memory access controller(DMAC) enable
high-speed transfer between SCA and memory.
