USB connection
To use the PicoLog CM3 with its USB connection, connect
the USB port on the rear of the device to a USB port on
your computer using the cable provided.
The first time you connect the device, Windows will install
the driver and then tell you that the device is ready for
use. You can then run PicoLog Recorder software to start
making measurements.
Ethernet port connection
Before connecting to the PicoLog CM3's Ethernet
port, you must first configure the Ethernet settings.
LAN connection
To use the PicoLog CM3 on a local-area network (LAN),
connect it to your network switch or network router using
the Ethernet cable provided.
Direct connection
You can also connect the PicoLog CM3 directly to the
network port on your computer. For this connection, you
will need to use an Ethernet crossover cable (not
supplied).
Power over Ethernet (PoE)
The PicoLog CM3 can obtain its power from the Ethernet
port as a Powered Device (PD) according to the PoE
standard (802.3af). To use this feature, you must connect
the unit to Power Sourcing Equipment (PSE) such as a
network switch, router or power injector that also supports
the PoE standard. Any standard Ethernet cable up to
100 m (about 328 ft) in length can be used.
Current clamp connection
The PicoLog CM3 is compatible with Pico Technology
TA138 current clamps.
Each current clamp has both a red and a black 4 mm
connector, which plug directly into the red and black
connections on the front panel of the PicoLog CM3.
Once the current clamp(s) are connected, they are easily
fitted around a supply cable by use of the lever on edge of
the clamp.
