1-2 Intellio C320Turbo User's Manual
Low Host Processor Overhead
The Intellio C320Turbo 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 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
both Chapter 2 and Chapter 5.
Status Indicator
The status of the communication lines is displayed on a series of diagnostic LED
indicators on the front panel of the external module, including TxD, RxD, DTR, DSR,
RTS, CTS, DCD.
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.
