Ethernet Port & Setup
Ethernet Port
The optional Ethernet port simplifies the communication network and avoids the need for an
external 3rd party Serial to Ethernet converter. It allows communications via an existing
Ethernet network. In some installations you will need to speak with your network (IT)
administrator in order to correctly set up your network. Applications, such as DataMod
(available via Contrec), can communicate over the Ethernet network to perform remote
monitoring and Data Logging operations.
Within the instrument’s calibration menus the Ethernet port uses the settings for the RS-485 port
that need to match a supplied Ethernet unit as follows:
•
Protocol: RTU
•
Baud Rate: 19200
•
Data Bits: 8
•
Parity: Even
•
Stop Bits: 1
Data mapping follows the same convention applied to Modbus registers.
Connecting 515 Ethernet to Networks/Routers
Ethernet 515s are set as default to DHCP (Dynamic Host Configuration Protocol), which should
allow your network/router to automatically find and assign an IP address to the instrument
(providing there are addresses available). If your network cannot locate the instrument you may
need to run the ‘Digi Discovery’ tool (Contrec guide available on request) or enter the Ethernet
module’s MAC address within your router settings. If required, the instrument can also be set
to a static IP address, however it is strongly advised that only IT competent persons access and
edit site network and 515 Ethernet settings. All Ethernet instruments are supplied with the
Ethernet module MAC address printed on the outside of the enclosure and also printed directly
onto the Ethernet Module itself (the Option card would need to be removed to view the physical
Digi Ethernet module).
Contrec Limited will not be held responsible for any changes made to customer router and
network settings. Further guides on how to access the module settings and discovering IP
address’ can be supplied upon request.
