Frequently Asked Questions

Do FISO monitors have NTP time synchronization capabilities?

Yes, all of our monitors support NTP time synchronization.

By default, a public SNTP IP address is present in all of our monitors. This IP address could manually be changed easily to point to a local NTP server. The typed name server address (ex: sntp.domain.com) is not supported. Only direct
NTP server IP address setup is. The change needs to occur at two levels, first within the monitor's configuration to enable the feature and then thru the IP settings as well.

Contact support to get instructions on how to proceed.

Is it possible to get temperature readings thru a network connection?

Yes, all EasyGrid's family monitors can be networked and are equipped with Serial
network connectivity by default along with an optional Ethernet port.


Within the MAN-0099 Communication Configuration user guide, you will find:

  • Digital Communication Protocol
  • Nortech
  • MODBUS Configuration
  • Supported Functions
  • Modbus Data Format Description
    • Modbus Register maps
    • Modbus Message Description
    • Modbus Example

Available Communication Protocols are:

  • Ethernet Protocol Configurations (thru the optional Ethernet port)
    • IEC 61850
    • IEC 60870-5-104
    • DNP 3.0
  • Serial Communication Protocols (thru the RS-485/422 port)
    • Modbus RTU;
    • Nortech (proprietary)*;
    • Modbus ASCII*;

*This serial communication protocol IS NOT available on EasyGrid BASE.


How fast is the EasyGrid refreshing the temperature readings from its connected sensors?

The inner light signal source is necessary to make reading off all connected sensors
goes from 1 channel to the next in a serial fashion.
The time lapse it takes for a given channel to be read again is equivalent to the
the time it takes for the system to complete a full "scan" cycle thru all enabled


For example: with 1 unique channel connected, the physical “poll” refresh interval is of
200ms. Should there be more than 1 channel on the equipment, then the “poll”
the interval between each channel is 500ms.

The EasyGrid monitor cycles thru all enabled channels in a serial fashion (one after
the other) and does so continuously.

In other words, should the EasyGrid equipment have 10 channels on it, a full-cycle
thru all channels would take 5 seconds to complete? (10 X 500ms)

This sampling rate is static and cannot be altered or modified. There are no user
settings available to change that.

As for the software side, the Nortech Client allows for displaying monitoring
information coming from the channels of a connected EasyGrid thru a USB or Ethernet

The speed at which the software polls the device goes from 1 second (Slow) to 1milisecond (fast). You can set that refresh rate speed within the Nortech Client
Software interface under the Monitoring tab.

The "refresh rate" within the Nortech Client and the "sampling rate" are mutually
exclusive and have no relations with one another.
