1 Introduction
1.1 Purpose of the manual
The purpose of this manual is to provide instructions for the fast and simple installation and operation the Industrial
Fiber Optic to Serial Converter, MCV1-FO-SE .
The manual starts with the product description and then provides instructions for the proper installation of its
hardware. Later on, the manual includes detailed information for configuration and operation.
1.2 General Description of the product
The MCV1-FO is an Industrial Multimode Fiber Optic to Serial converter, that allows to extend the communications up
to 2.7 Km and without interferences for electrical noise.
The main features of the product are:
•Industrial DIN rail mountable case
•ST Connectors.
•One multimode Fiber Optic Port (TX & X)
•One Serial Port S232 / S485 / S422 (Not simultaneous)

2 Wiring
2.1 General Wiring
MCV1-FO-SE wiring is very simple and intuitive. There are three different connectors.
-Serial port connector in industrial pluggable terminal block.
-Optic fiber port connector in ST type.
-Power supply Terminal block (+10 a +30 Vdc)
First connect the device to an appropriated power supply, then the Serial port and finally the two Optic Fiber
connectors (TX Transmitter and X eceiver)

2.2 Standard Connection
The most common connection for MCV1-FO is serial tunnel (point to point). This way it’s possible to extend a serial
connection up to 2.7 Km with all the characteristics of an optical fiber.
The use of the MCV1-FO also allows you convert the type of serial ( S232, S485 or S422), that mean that you can
connect to the equipment two different type of serial in each one of the ends of the tunnel.

2.3 Ring Connection
The ring connection allows interconnecting several MCV1-FO using a ring. One of the devices must be the master and
the rest slaves.
To use the ring mode each of the MCV1-FO that connected to the slaves must have the Jumper of Configuration in
ING MODE in ON position, also the Master must have the ING MODE in OFF position.
Each MCV1-FO will be able to use the type of serial ( S232/ S422) that adapts to the equipment that goes connected
on it, with exception of the S485 protocol, this is because the ring mode receives and transmits simultaneously
leaving the S485 out for being a HALF DUPLEX protocol.
The data sent by the Master will be received and forwarded by all the slaves belonging to the ring. Finally this data
will arrive again up to the Master. Also every time a slave transmits something, all the slaves between the one that
transmitted and the Master, will receive the data too. To know which device will receive data, it is important to know
the data direction of them.

3 Configuration & LED’s
The configuration of the converter is done by jumpers located in the top side of the device as it’s shown in the
following figure.
There are two configuration jumpers. They will determine how the converter will work.
JUMPERS
1) ING MODE
Enable/disable the optical fiber to work on ing Mode.
In this mode data receive on the fiber X Port, will be transmitted to the serial port and forwarded to the
fiber TX Port. This way you can create an optical fiber ring.
This mode is not available for S485.
2) Serial communication mode, S485 or S232/ S422
Enable/disable the converter to use the S485 or the S232/ S422 Terminals.
ing mode is not compatible with S485 Mode.
LED’s
TX - Blinks when data is sent to the Optical Fiber
RX / LNK - Blinks when data is received on the Optical Fiber. It also works as Fiber Link, when the LED stays steady
on, the converter is not linked to any other converter.
