supporting technology innovator Icoteq in the creation of a sensor-fusion board capable of aggregating sensor data from multiple channels for transmission to a host over a TransferJet connection. The reference design comprises two embedded host boards and two Toshiba TJM35420XLQ TransferJet modules with Antenova SR4T014 couplers. Various storage and power-supply options are also available, and an Ethernet port is also provided. The reference design also provides
software that includes a Board Support Package (BSP) and TransferJet drivers, as well as application-level software to enable design engineers get a TransferJet demonstration up and running quickly for evaluation and development.

TransferJet’s high data throughput rate allows many document types including user manuals, instructions, software updates, maintenance logs and process data to be exchanged quickly and easily. The close proximity of the TransferJet connection ensures that operators are communicating with the intended equipment, and not inadvertently connecting to a different machine. TransferJet also enhances security by allowing equipment to be designed without external connection ports thereby eliminating any opportunity to insert unauthorised media and download data, as well as offering the ability to design fully sealed machines.
Another advantage is that data can always be exchanged via TransferJet, even during periods when the enterprise LAN is down through a fault or routine maintenance. Alternatively, TransferJet can be deployed by utilising embedded TransferJet technology to create specific applications whereby transactions can be managed by autonomous transceivers located in either fixed or moving positions. Applications such as mobile robots are generally battery operated and cable-free, yet they need to exchange data with other
machines, or receive configuration updates or load new software when changing tools. These data exchanges must be rapid to ensure that productivity is maximised. Here, the point-to-point wireless connectivity and proximity-based nature of TransferJet allows large numbers of robots to coexist in a confined space and communicate with paired devices using the full effective bandwidth and without any disturbance to neighbouring units. This contrasts with connections made using a network based wireless technology such as Wi-Fi. TransferJet transceivers can also replace expensive ruggedised connectors for equipment used in harsh environments. TransferJet can provide simple and reliable means of transferring data from a moving mechanism, such as a pan/tilt security camera, to the host security system. In this case, high-speed wireless data transfer allows the camera to send high-resolution images or video to the security system, and eliminates any potential for connector cable failure due to corrosion or fatigue.

environments can be simplified by designing systems around dedicated TransferJet modules. Toshiba’s TJM35420XLQ module, for instance, is ideal for use in embedded systems. It integrates a modem, filter and crystal, and SDIO 3.0 (UHS-I) host interface within a very small form-factor measuring just 4.8mm x 4.8mm x 1mm. With this advanced solution, an RF designer only needs to develop a 50Ω micro-strip line to complete the integration. As far as TransferJet couplers are

concerned, commercially available couplers such as the Antenova ZOMA SR4T014 allow straightforward integration, thereby simplifying RF design. Alternatively, a customised coupler can be designed directly into the PCB layout, although this requires RF-coupler design know-how. Machine builders need to be able to access know-how and support while designing TransferJet solutions, whether communicating with mobile devices or other TransferJet transceivers – either embedded within or separate to the equipment or machine. To address this need, Toshiba has created a development kit and reference design for evaluating TransferJet communication links, as well as
business users rely on these standards continuously, every day, to execute a wide range of tasks, from setting up ad hoc networks, to exchanging large files, and financial transactions. However, the industrial sector has some specific needs including security, the ability to connect to moving parts, quick connectivity and high data throughput that are not fully met by these solutions. TransferJet has been developed to
address demands for an easy and secure means of transferring large files quickly, directly between devices, and is now standardised as ISO/IEC 17568. Ideally suited to enable convenient, reliable, secure and rapid connectivity in industrial applications, it addresses many of the challenges found working in harsh environments. Toshiba and its partners have provided tools and support, including hardware and software, to help design engineers take advantage of TransferJet’s Touch and Get simplicity in a variety of machine-to- machine and machine-to-operator communication scenarios.
