1. Introduction
All technical information, descriptions and illustrations contained in this operating, maintenance and
installation manual remain our property and shall not be used otherwise than for operating this system,
nor shall they be copied, reproduced or passed on to third parties or brought to their notice without our
prior written consent.
The information represented in this manual is in keeping with current standards and is subject to later
alterations.
This manual contains important instructions referring to safe installation, commissioning, operation
and maintenance.
Read this manual carefully before starting up the protocol converter and observe the instructions.
In order to comply with the guidelines for electro-magnetic compatibility in industrial PCs (or other
variants) only CE-certified components are used in compliance with project-specific requirements.
It is to be noted that the protocol converter (SEC2) has not been protected against lightning and the
operator should, if desired, take appropriate protective precautions.
All trademarks and brand names contained in this user manual are for identification purposes only and
can be owned by their respective holders.
Finally, we want to draw your attention to the fact that any warranties with respect to delivered goods
will be invalid in the event that:
Operation, servicing and maintenance are not carried out accurately according to the
instructions; repairs are not carried out by our personnel or without our prior written consent.
Commissioning is not carried out by our personnel or we have not given our approval for the
commissioning or the commissioning is carried out by untrained personnel.
The unit is used inadequately, incorrectly, negligently or inappropriately or for a purpose other
than that originally intended.
The serial number is removed from the product.
For your protection, observe the following safety precautions when setting up your equipment:
Follow all cautions and instructions marked on the equipment.
Ensure that the voltage and frequency of your power source match the voltage and frequency
inscribed on the equipment's electrical rating label.
Never push objects of any kind through openings in the equipment. Dangerous voltages may
be present. Conductive foreign objects could produce a short circuit that could cause fire,
electric shock, or damage to your equipment.

2. Hardware Description
2.1General
As hardware platform for the protocol converter the “Small Embedded Controller”–SEC2 is used. This
maintenance free solution offers a maximum usability, reliability and optimal price-performance ratio.
Intensive tests of the embedded controller are done in our company.
Before and after a 48 hour burn-in test each device must run through a complete function test.
All components are cooled passively.
The mains power supply is 9 - 48 V DC.

2.3Hardware Components
2.3.1 Onboard RS232 Interfaces
The serial interfaces have an RJ45 connector available. COM 1 is software configurable as
RS232/RS422/RS485, COM 2 to COM 4 can be used as RS232/RS485. See the pin assignment
below.
Attention! COM1 and COM2 –COM4 have a different pin assignment!

2.3.3 Onboard Serial Console Port
The serial console port is used for locally accessing SEC2 by RS232 port. The console port uses the
RJ45 connector and is next to Ethernet port. Therefore, please be careful to plug in the right
connector!
In addition to the serial console signal, the console RJ45 port also provides GPIO (programmable I/O
signal) function. The GPIO port is CMOS I/O and programmable as digital input or output. Power up
setting is digital input mode with 75K ohm pull up resistor.

2.3.4 Power Supply
The main power supply of SEC2 is 9 - 48 V DC. Please pay attention to the correct polarity and input
voltage.
Power supply inputFigure 9:
The female connector is always supplied. This connector has to be used. By connecting the cable with
the connector, the correct polarity must be kept. The wire cross-section must be at least 0.5 mm².
