Introduction

The M-4132 module is specially designed for the remote maintenance
solution with voice streaming. This module provides 2 major technologies
on networking: Voice streaming and Pair connection functions. The Pair
connection means that the user can operate remote COM port device via
Ethernet TCP/IP protocol just like a local COM port and the Voice
streaming means the user can talk to remote operator while operate remote
COM-linked devices. Refer to the following graph. Furthermore, M-4132
integrates the Virtual com technology. That can resolve the insufficiency
of real com port in PC. By applying this technology, the maintenance man
can take the remote maintenance or monitor whatever time or place.

2.2 Wiring Instructions

The communication interface of M-4132 includes RS-232, RS-485 and
Ethernet. The wiring instructions are described in section 2.2.1, 2.2.2 and

2.2.3.

2.2.1 RS-232 connection
There are two types of RS-232 ports, DTE (Data Terminal Equipment,
like M2M series, PC, Serial Printers, PLC and Video Cameras) and
DCE (Data Circuit-Terminating Equipment, like modem) type, and that
the signal names and pin numbers are the same, but signal flow is
opposite!

The M-4132 module is a DTE and the user can uses “3-wire” RS-232
or “5-wire” RS-232 to connect. When connecting the M-4132 to a DCE
device, the user just needs to match the signal names. When connecting
the M-4132 to a DTE device, the user needs to use a crossover cable
(TX crosses to RX, GND to GND,), as shown in the figure 4, 5.

A3: Please follow the steps to check below.

Step 1: Confirm Client has already login the Server and the user can

find the host name of Client in the “Login list” at Server’s
“Operation Mode” page..

Step 2: Confirm Server and Client are at “Pair Connection” mode and

it shows “Your Status: Pair Connection with Client (IP)” at
Server’s “Operation Mode” page.

M-4132 User Manual (Version 1.60, May/2014) PAGE：68

Step 3: Confirm that the Com Port devices is connected with Server

and Client has the same communication settings with
Server’s “Operation Mode” page. If it is different, please
break the connection and change the settings then reconnect
the client.

Server’s “Operation Mode” page

Step 4: Confirm the Cable connected Server/Client to Com Port

device is wired correctly. If the connection is RS485, the user

M-4132 User Manual (Version 1.60, May/2014) PAGE：69

can refer to user manual section 2.2.2. If the connection is
RS-232 and the Com Port device is a data circuit-terminating
equipment (DCE), the user just needs to match the signal
names to connect Server/Client to Com Port device, else the
user needs to use a crossover cable to connect.

Some Com Port devices will wait forever for one of the
handshaking lines to go to the correct level. Depending on the
signal state it might sometimes work, other times it might not.
Here we connect the M-4132 and the Com Port device via
handshake looped to avoid the Com Port device waits
handshake line signals, as shown in below.
