2.0 Product Description
The TransNEXT is a rugged license-free wireless communication device well suited for a variety of
SCADA and telemetry solutions using serial and IP/Ethernet.
2.1 Key Features
TransNEXT units include the following key features:
Backwards-Compatible – Over-the-Air Compatible with TransNET, with similar or better RF
•
performance in real-world field installations.
Over-the-air (OTA) reprogramming – This facility provides a simple means to non-intrusively
•
broadcast a firmware upgrade to an entire field of remotes, using a copy of the firmware image
currently running in the TransNEXT master radio. This feature operates slowly to avoid conflicting
with payload data and to allow interoperability through an existing TransNET network.
Optional E-ink display (select models only) – This display provides a convenient tool for
•
installation, local diagnostics, and troubleshooting. The E-ink display maintains the last screen
image following a power failure.
IP Payload – First introduced in the MDS SD™ this facility performs local ethernet to serial
•
conversion, providing an efficient means to connect compatible ethernet devices.
•
Small Form Factor—The unit is housed in a rugged enclosure suited for operation in harsh
industrial environments. It requires only protection from direct exposure to the weather and may be
easily mounted inside a NEMA enclosure for outdoor applications when required.
•
User Interface—Multiple user interfaces are provided for configuration and monitoring of the unit.
These include USB, web, SSH and local serial (using "+++" to temporarily override the payload
data interface)
NOTE
The TransNEXT is designed for secure environments. As such, management of the device does
not support Telnet, but instead implements the more secure SSH protocol.
NOTE
For units certified and installed in hazardous locations, use only the serial or Ethernet
connections on the unit's front panel. Do not use the USB port in hazardous locations.
•
Network Management System— TransNEXT is supported by GE MDS PulseNET, a Network
Management System (NMS), providing monitoring of small- and large-scale deployment of all GE
MDS devices. (*** for interoperability, TransNEXT appears as a TransNET device)
2.2 Typical Applications
MDS TransNEXT is the successor to the MDS TransNET radio. It builds on the flexibility of the
predecessor product and serves a wide variety of traditional applications.
Multiple Address Systems (MAS)
This is the most common application of the transceiver. It consists of a central control station (Master)
and two or more associated Remote units. An MAS network provides communications between a central
host computer and remote terminal units (RTUs) or other data collection devices. The operation of the
radio system is transparent to the computer equipment. When used in this application, the transceiver
provides an excellent alternative to traditional (licensed) MAS radio systems.
