1-2 Intellio C320Turbo/PCI User's Manual
Low Host Processor Overhead
The Intellio C320Turbo/PCI is equipped with two high performance processors
(TMS320) on both the Control Board and the CPU/Basic Module and 512KB on-
board memory to relieve the host’s CPU workload of all data and I/O handling tasks.
The memory buffer holds transmitted and received data to prevent data loss.
ASIC Design, Compact Size
The Intellio C320Turbo/PCI is also equipped with MOXA custom-designed ASIC
chip, which replaces lots of conventional IC and hence reduces the board to half-
size, increases the operation performance, and lowers the failure rate of the board.
Distance Extensible
Normally, a standard 2-meter DB25 to DB25 cable with 25 signal pins links the
Control Board to the external module. However, for the purpose of extending the
distance between Control Board and external modules to above 2 m and up to 100 m
(328 ft) or improving power insufficiency problem of the PC host, external power
and the cable specially fabricated with only 10 signal pins should be used as
illustrated in chapter 2 and chapter 5.
Versatile Connection Options
There are two connection options, Desktop and Rackmount, for the external
modules to meet various connection requirements. For Desktop option, CPU Module
and UART Modules are provided. For Rackmount option, Basic Module and
Extensive Modules are provided with rack mount capability. Besides, you may
choose flexibly from modules with DB25/RJ45, male/female, or RS-232/RS-422.
