Connecting Cables to the PT Port
1. The EMI used in Europe and Southeast Asia is composed of sensors that need to connect to the
SmartLogger separately.
2. The SmartLogger2000-10-C/11-C can connect to a PT100/PT1000 temperature sensor through a
PT port.
3. If the AI port has connected to a temperature sensor, the PT port can be reserved.
4. The PT1 port can connect to a three-wire or two-wire PT100/PT1000 temperature sensor,
whereas the PT2 port can connect to only a two-wire PT100/PT1000 temperature sensor.
5. If the PT1 port connects to a two-wire PT100/PT1000 temperature sensor, you need to short-
circuit the GND port to one – port using the delivered short-circuit cable.
6. For details about the cables and cable connection operations, see the documents delivered with
the PT100/PT1000 temperature sensor. The PT port on the SmartLogger is marked + and –.
Connect cables correctly according to the silk screens.

Connecting Network Cables to the Ethernet Electrical Port
1. The SmartLogger provides two Ethernet electrical ports, through which the SmartLogger can
connect to a third-party device.
2. The SmartLogger can be connected to an Ethernet LAN switch, router, or POE device, and then
connected to a PC. It can also be directly connected to a PC. Select the connection device
based on the actual networking scenario.
3. If the cable between the SmartLogger and the PC over the devices such as a POE is routed
outdoors, connect a POE SPD to the POE to enhance the surge protection function. Connect
the POE port on the POE to the PROTECT port on the POE SPD.
4. Verify that the Ethernet communications cable is no longer than 100 m.
