rather than stay continually charged. This is sufficient to ensure the logger doesn’t self-
discharge and will maintain the logger’s full charge status.

Power Adapter
The OM-DAQLINK power adapter is used to power the OM-DAQLINK-TEMP and OM-
DAQLINK-TEMPRH units. The mains adaptor (AC/DC adaptor) converts mains power (from a
wall outlet) to a voltage suitable to the OM-DAQLINK hardware unit.
Output: Capacitor filtered 9 to 12 VDC, 300 mA
Female plug, center negative
Note:
Only use Omega-supplied power adapters to avoid damaging the units with incorrect
power supply.

Data Logger Battery Life
Battery life depends on the logger sampling rate, type of sensor, and number of measured
sensors.
OM-DAQLINK-TEMP and OM-DAQLINK-TEMPRH can last up to six months on a charged
battery depending on logger configuration.

USB Communication Cable
A mini USB communication cable is supplied as part of the DataSuite software kit. This cable
connects the OM-DAQLINK data logger to the OM-DAQLINK PC workstation. When connected
to the PC the logger can communicate with the software for configuration and data download
purposes, for example.
The USB cable also powers the logger when connected to the PC but it does not charge the
internal battery.
Note:
The USB driver is installed as part of the software installation process. Without this driver
the PC won’t detect the logger. To avoid compatibility problems do not connect the logger to the
PC before installing the USB driver.
