Procedure
Step 1
Prepare a cable with an appropriate length, strip a proper part of the insulation layer from one
end, and connect the end to the SUN2000 terminal block.
You are advised to use a DJYP2VP2-22 2x2x1 PC cable or a communications cable with
a conductor cross-sectional area of 1 mm

and a cable outer diameter of 14–18 mm.
For details about how to strip and connect the cable, see the SUN2000 user manual.
Step 2
Connect the other end of the cable to the COM port of the SmartLogger. For details, see

The RS485 IN and RS485 OUT ports on the SUN2000 can both connect to the
SmartLogger. This document uses the RS485 OUT port as an example to describe the
connection between the SUN2000 and the SmartLogger.
When connecting the cable, ensure that the RS485A (OUT) port and RS485B (OUT) port
on the SUN2000 respectively connect to the COM+ port and COM– port on the
SmartLogger.
