The Teleterm W3 ISA100Wireless Radio Protocol Interface Node for serially connected devices provides a convenient means to network all your devices over an ISA100 wireless network


The Teleterm W3 ISA100 Wireless Radio Protocol Interface Node for serially connected devices provides a convenient means to network all your devices over an ISA100 wireless network.

Attach a Teleterm W3 ISA100 Wireless Radio Protocol Interface Node to each device and transmit readings and alarms wirelessly to your control centre, eliminating costly installation network cabling.

Serially connected devices

The Teleterm W3 has a standard RS232/485 serial communications link that can be connected to any instrument via it's serial port utilising standard Modbus or any bespoke serial protocol.

Supports a wide range of Radiation Monitors

The Teleterm W3 ISA100 Wireless Radio Protocol Interface Node has a standard RS232/RS485 serial communications link to connect to a radiation monitor and is supplied with built in support for a wide range of radiation monitors including models from Canberra, Lab-Impex Systems / Ultra Electronics (See the list of supported radiation monitors in the Specifications). If your radiation monitor is not listed, consult with your Omniflex representative for availability.

ISA100.11a wireless network

ISA100Wireless is an international standard (IEC 62734), and is an open wireless network that is scalable, reliable and secure.

ISA100 comes with “IPv6” addressability which makes it the only industrial network protocol compatible with the “Internet of Things”.

ISA100 operates over the 2.4GHz ISM (non-domestic) band using the widely supported IEEE802.15.4 radio standard. This means no special licencing is required to operate an ISA100 wireless network.

Being an industry standard network, the Teleterm W3 Wireless Radiation Monitoring Interface Node can be used with any ISA100 compatible Wireless Access Point (WAP) to connect your monitors to your central monitoring and control system.

The ISA100 wireless standard integrates high level cyber security features to ensure data integrity, confidentiality and authenticity.

Simple configuration

The Teleterm W3 as well as serial Modbus comes preloaded with support for a range of radiation monitors allowing the minimum of configuration required to connect a radiation monitor to the wireless network.

Fully configurable using Omniset.  Two steps for configuration - Step 1: Configure the ISA100 network parameters. Step 2: Set the radiation monitor type and respective parameters.

ISA100 network topology

There are two network topologies supported by ISA100. Star network topology, where every monitor is in range of a Wireless Access Point; and mesh topology where monitors out of range of the network access point pass their data on to other monitors to relay that data back to the Wireless Access Point.

Supports “DuoCast” which allows network redundancy.

Consult your ISA100 network installer for the most appropriate configuration for your network. Often a simple site survey is required to determine the possible locations for ISA100 network nodes

Update rate

The update rate of data on the ISA100 network can be adjusted from 8 to 3600 seconds. A faster update rate reduces the number of devices that may be connected to a single network.

The Teleterm W3 ISA100 Wireless Radio Protocol Interface Node is shipped with a default update rate of 8 seconds, which allows up 500 devices to be connected to the ISA100 wireless network.
