NTMS4i Network Hardware Specifications

Description

The NTMS4 (Network Telemetry Monitoring System with 4 ports) is a standalone Ethernet network device. It operates with an IP address and a network MAC address that acts as the important "Networked Robotics Unique ID". The NTMS4 continually collects temperatures and other scientific and environmental data types such as carbon dioxide concentration, liquid nitrogen level, voltage, electrical current, pressure and many other parameters from up to four (4) diverse data sources. These can either be via direct connections to high-end scientific instruments from multiple vendors, or Networked Robotics' own advanced digital sensors. In general, each of the 4 ports of our NTMS4i hardware can collect data from any interface, or any data source, in any combination. The newer NTMS4p version currently supports most but not all of those interfaces.

Operation

One of the primary functions of the NTMS network hardware is real-time data integration. Through individualized connectors or other kinds of interface hardware, the NTMS is able to access the communication ports of freezers, cryofreezers, incubators, shakers, and incubated shakers from multiple manufacturers and understand the unique data language of each machine.

Temperatures and other kinds of environmental data are requested of the NTMS through the network by the Tempurity™ Server at time intervals defined at the server. The current default Tempurity System™ network-side data collection period is one minute. Data collection at the local level, between our NTMS hardware and the instrument, is more frequent. It varies by interface, but generally data collection of new values is occurring every three or four seconds for each connected "monitored device". The NTMS's most recently collected data is the value reported to the network collecting process (the Tempurity Server).

See the Networked Robotics "Products" page, or the hardware documentation page for a list of our interface and sensor products and their associated hardware manuals.
