OMC-045-II
Preface
The OMC-045-II is used for collecting data and processing it. The data can be send through GPRS. For
this function you need a SIM card.
Important:
Disable the PIN code (use a mobile phone to check / disable the code)
Check the settings of the mobile provider
Check the settings for the communication with the FTP/Mail server
Check if the mobile provider accepts FTP/Mail communication
.
Mechanical changes to the OMC-045-II, has to be preformed inside a protected surrounding. Contact with
high air humidity, sweet and salt water has to be avoided
Warning ESD: By ignoring the ESD instructions, you can damage the OMC-045-II. This can create
indefinable behavior. This is difficult or impossible to repair.
The OMC-045-II has to be assembled inside a cabin on a DIN rail. In case this cabin is located outside, it
has to be IP65. For (near) sea / offshore locations, it must be IP66!
It is required to have knowledge of the sensors you would like to connect, since you have to configure
them via OMC-programmer.
Examples can be found in the appendix.

OMC-045-II
1Description
1.1 General
The OMC-045-II is a multipurpose data acquisition platform with integrated GPRS modem and GPS
receiver. The OMC/045-II is intended for measurement of environmental parameters, e.g. for hydrological
and meteorological applications.
The connections are divided over three clasping connector rows.
X2 The row that contains mostly power connectors.
X3 The row that contains digital inputs and serial
communication
X4 The row that contains connections for analog sensors
and alarm contacts.
All configurations are been made through port X1. This is a USB
connection. This connection has to be connected to a PC, with
an A to mini B USB cable. OMC-Programmer uses this
connection to read and write configuration to the OMC-045-II
The dimensions of the housing are L x W x H 84 x 92 x 55 mm.
The extending objects are calculated in these dimensions. These
are the SD card, X2 mini USB connector and the fuse holder.
Also the DIN rail connector is not calculated in the dimensions.
The needed dimensions to connect all the connectors when the OMC-045-II is connected in the DIN rail
are L x W x H 120 x 92 x 55. This is because on the back of the OMC-045-II, there are 2 antenna
connectors. On the top there is no extra space needed, because if connected in a DIN rail the front is
open and accessible.
Depending if an antenna cable is used, there is more or less space required on the backside of the OMC-
045-II.
Color Connector Type Network Frequency
Gold SMA GPS
Silver/Grey FME GSM/GPRS 900 / 1800 Mhz
The fuse holder makes it simple to replace a burnt fuse.
Through the LED D10, the status of the OMC-045-II can be seen through the blinking of the LED. The
status can be recognized without connecting the PC. In chapter 8.10 the function of the LED is explained.

2Starting with the OMC-045-II
2.1 Handling precautions
No user-serviceable parts inside.
For connecting the connections on the OMC-045-II datalogger, a screwdriver type 0.4 x 2.5 is needed.
Other types, then this screwdriver, damage the connectors. Damaged connectors are less reliable.
All cables should be connected using cable shoes.
2.2 Qualification of the engineer
Installation
When connecting the sensors, check the voltages and interfaces of the datalogger and the sensor. Not all
sensors are protected against faulty wiring. The datalogger could also be damaged if electrical
specifications are exceeded. For example draw to many current or deliver a high output voltage.
Warning ESD: The OMC-045-II must be handled with care and never exposed to ESD discharges. When
installing a sensor or other wiring, make sure there is no power on both devices. ESD discharges could
cause invisible damage, which endangers long term stability and proper operation. For more information
see chapter 3.2
2.3 Preparation
The wireless data functions will only work when an activated SIM with a valid subscription is placed in the
OMC-045-II. In OMC-Programmer the configuration and network settings must also mach those supplied
by the provider. The pin code of the SIM card must be removed, before insertion in the data logger. To
prevent problems with the SIM card it can be inserted in a mobile phone of GSM data modem. In a Mobile
phone or GSM modem the GPRS, SMS and GSM data functionality can be tested.
For placement of SD card, Read the procedure in 7.6.2 .
The SD card is not Windows compatible formatted. Prior of insertion of a new SD card it must be
specially formatted in Obsermet format. All the sectors on the Card must be filled with “0x00”. In some
application this is called a zero fill. For more information read chapter 7.6.2 .
The included SD card is already formatted!
Prior to connecting the data logger to a PC OMC-Programmer must be successfully installed. The setup
also installs a driver for the USB virtual comport. If this driver is not present when a OMC-045-II is
connected to a PC, conflicts may occur.
Check for the latest version of OMC-programmer the support page of www.observator.com (Meteo &
Hydro).
