 If the SmartLogger needs to be connected to an EMI and multiple SUN2000s, connect the EMI at
the end of the daisy chain, and verify that the port connected to the EMI has a unique
communications address. For the daisy chain connection, see
Connecting Multiple SUN2000s.
 The SmartLogger provides two PT ports. The PT1 port can connect to a three-wire or two-wire
temperature sensor, whereas the PT2 port can connect to only a two-wire PT100/PT1000
temperature sensor (PT100/PT1000 for short).
 If the AI port has been connected to a temperature sensor, the PT port can be reserved.
 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.
