Mcsc (Multiple Channel Serial Communication) - Moxa Technologies MiiNePort E2-H User Manual

MiiNePort E2/E3
ATTENTION
Check the following if AutoCFG is not working properly on your device:
1. Make sure the AutoCFG function is enabled (the function is enabled by default).
2. Check to see if the TFTP Server is working properly.
3. Make sure the specific configuration filename is correct: MiiNePortE2.txt, or whichever is appropriate
for your device.
ATTENTION
There is no theoretical limit to the number of MiiNePort E2 modules that can be connected at the same time
to one subnet for conducting an AutoCFG task.
ATTENTION
Even if you do not want to use the auto configuration function, the module will still go through the process of
searching for the MiiNePort E2.txt file on the network every time it starts up if you do not disable the AutoCFG
function on your MiiNePort E2. The MiiNePort E2 will resume normal operation if it cannot find which network
TFTP server the file is stored on. On average, it will take less than five seconds to conduct a search. Your
MiiNePort E2 will work properly with its original configuration even if it does not complete the AutoCFG task.
ATTENTION
If you do not want the AutoCFG function to remain active after you've successfully finished the
auto-configuration, we suggest that you DISABLE the AutoCFG function when you are creating your
MiiNePortE2.txt file, since doing so will prevent the AutoCFG activity from occurring the next time your device
is powered on. Refer to Chapter 7: Web Console Configuration for configuration details.

MCSC (Multiple Channel Serial Communication)

NOTE
MCSC is only supported in the MiiNePort E2
The Motivation Behind MCSC
An embedded device server only provides a limited number of physical serial ports to communicate with the
device's main system. As a result, users with one physical serial port are generally limited to a single
application. If you want to implement multiple serial-to-Ethernet applications (keep in mind that the MiiNePort
E2 has only one physical serial port), additional physical serial ports will be needed. Unfortunately, providing
additional physical serial ports increases
hardware costs. Moxa's MiiNePort E2's MCSC
is designed to solve this dilemma. MCSC
(Multiple Channel Serial Communication) is
a lightweight, pure software solution that
enables multiple serial-to-Ethernet
applications all through one physical serial
port, without any incremental hardware
costs. In short, MCSC allows multiple
application channels to share a single
physical serial port at the same time.
