Connecting a Computer to the DS-Tracer
The DS-1000 I-V Tracer provides two interfaces; an RS-232 and USB port. The
RS-232 interface uses a standard female, 9 pin connector located on the DS-
Tracer front panel. The standard USB connection is labeled “Main USB.” Use
either of these connections depending on the configuration of the computer
running the IVPC program. However, only one of these ports should be
connected at a time.
Note: Special USB drivers must be installed on the computer in order to use the
USB port. See the section “Appendix B DS-1000 USB Drivers” for details on
installing these drivers.
Connecting a PV Module to the DS-Tracer
The DS-Tracer is connected to the PV array or module with the test leads
provided. Before connecting a PV module, be sure the DS-Tracer power switch
is ON. The test lead is designed to remain connected to the DS-Tracer at all
times. It is typically unnecessary to remove this from the tracer.
For safety, the test lead should never be disconnected from the tracer while
the other end is connected to a PV system. Doing so could present an electric
shock hazard.
For safety, it is recommended that connections be made to the PV array
through a system disconnect switch rated at full PV power.
With the test lead attached to the DS-Tracer, connect the test leads to the PV
system.
