2. Plug the power supply into a suitable AC outlet. The Status LED on
the particle counter should illuminate green.
Remote Particle Counter Using DC Power
Connecting the Remote Particle Counter to a
Computer
You can communicate with the particle counter using Modbus TCP
over Ethernet.

TCP over Ethernet is the preferred method of communications
with the particle counter. Using the 8-pin RJ-45 socket described above,
Modbus

RTU provides compact, binary representation of the data
contained in a register within the instrument memory. If you used PoE+
to provide power, you have already made the necessary communications
connection to the particle counter. 802.3at PoE+ carries both power and
communications through an Ethernet cable to the Remote Particle
Counter. If DC Power is used, the PoE+ option will not be required to
power the unit but the unit will operate fine with PoE+ also present. No
need to disable PoE+ for units running with DC power.
Tubing Installation
Connecting Vacuum Tubing (Models 7201, 7301, 7501,
7310, 7510 only)
The 7201, 7301, 7501, 7310, 7510 models do not have an integrated
pump to move particles through the instrument. Instead, it uses a critical
or sonic orifice to maintain a steady flow of air and particles.
