Data output stream description

 

On the USB and Ethernet serial interfaces the following output stream provides the measurement data.


Example of the output stream:


"D02-032 SWV9.02 ESNE03-1120" T 25.10 f 8701.36 df 0.92 Fv 735 ph 90 V 0.000 D 0.002 I- 2 I+ 2 Q 0.9824078 fr 8701.3590000 df- 8701.8100000 df+ 8700.8950000 Tc nan Tp 25.10 Te 25.12 E 00 A 1

Connect the USB and Ethernet interface to a terminal


The Electronic Box provides a RS232 over USB and Ethernet measurement output stream which can be read by the Rheonics Control Panel Software or by a Terminal program (ex. Tera Term).


For output stream details see section above Data output stream description.

USB connection to Tera Term terminal

 

Windows 10 does not need any USB driver installation for Rheonics Sensors.

For Win7 and others Install USB Driver, check manual or contact support.

The driver provides a virtual COM-Port on the computer to which you can connect with the terminal or LabView program.


Steps to connect and acquire data over USB:

 

  • Connect the micro USB cable to the electronics box. Connect the other end to a free USB port on the computer. 
  • Start the terminal and select the COM-port

  • Set the Serial port settings


  • The terminal is printing out the received measurement data stream from the electronic box.
  • You have the possibility to log the stream and evaluate the data in Excel or capture and parse the data in other data acquisition systems.


Ethernet connection to Tera Term terminal


This section describes how to connect the electronic box via Ethernet to the Tera Term terminal.

Connecting the Electronic Box to your network (DHCP)

  • Connect the Electronic Box with a Ethernet cable to your network
  • Power the Sensor electronics, unless already powered.

The Electronic Box is set default to obtain an IP-Address from the network (DHCP)

 

Connecting the Electronic Box to your network using STATIC IP Address

User RCP to set a static IP address for the Sensor.

Refer to RCP manual for detailed instructions on setting the electronics to use either DHCP or Static IP address.

 

Connect using Teraterm to the Sensor electronics over ethernet (serial):


Enter the IP-Address and the port number:  <IP>:<Port>

Default port is 10001


The terminal is printing out the received measurement data stream from the electronic box.

You have the possibility to log the stream and evaluate the data in Excel or parse the data and store in other data acquisition systems.

Other communications


 Rheonics Sensor electronics has multiple analog and digital communication options.

Analog

  • 4-20 mA
