2.1.3
Use
POE
switch
After connecting the LAN connector and POE switch, supply power to the main unit.
If a POE switch is used to provide power, a switch that complies with IEEE 802.3 bt POE
power delivery standards must be selected, otherwise damage to the monitoring system will
result.
2.2
Parameter Setting
Before measurement, parameter s e tting is required, please read
3720-06 MODBUS Communication Protocol before setting.
Connect the 3720-06, 3720-06 power supply, USB-RS485 converter (converter,
cable), PC or 3720-06, POE switch, router, and PC before setting parameters.
Sampling time setting: 1 second step set in the range of 1-60 seconds All data within the
sampling time period is totaled and output via analog output (4-20 mA).
This sampling time is common to all channels.
The factory default setting is 60 seconds.
Output range setting: Sets the particle count range and concentration range. 4-
20mA analog output is generated within the set range.
The setting range is shown below. This output range setting can be set
for each channel.
The factory default setting is 02 (0-100CNT).
