Starting 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.
