Abstract
New Modbus TCP/RTU Bridge from VxI
PSU manufacturer VxI Power has developed a new bridge device that allows power supplies with Modbus RTU communications capability to be controlled and monitored over the Internet or any other WAN or LAN.
As well as acting as a communication bridge between the Modbus RTU and Modbus TCP protocols, the IPM01 device features an embedded HTTP server that enables the user to view and configure PSU parameters via a web browser.
The device incorporates an RJ45 Ethernet socket and a 3-wire serial interface for either RS232 or RS485 communications – the latter capable of supporting multiple RTU clients. Both versions can deliver baud rates of up to 57600, and LED indicators are provided for serial TX and RX activity.
Housed in an industrial DIN-rail-mount enclosure measuring just 73 × 59 × 22 mm, the device has an input voltage range of 9–32 V and an operating temperature range of −20°C to +50°C as standard, which can be extended down to −40°C on request.
While particularly suitable for use with VxI’s Oracle range of battery-backed Modbus power supplies, the IPM01 bridge can also be used with any other Modbus device, subject to configuration.

Ocean Optics Goes Mobile
Ocean Optics has released a mobile application for iOS devices to the Apple App Store. The free application allows users of Apple’s iPhone, iPod touch and iPad to access helpful spectroscopy calculators, browse application support materials and access the latest technical product information on Ocean Optics spectrometers, sensors, light sources and fibre optic capabilities.
According to Ocean Optics mobile devices have become such an integral part of everyday life that having access to product information in a mobile format is as logical as having a website or a catalog, and their goal is to provide customers with useful application, spectroscopy and product information in the format they want, whenever and wherever they need it.
The Ocean Optics mobile application is available by searching ‘Ocean Optics’ in the App Store. It is compatible with Apple iPhone, iPod touch and iPad devices running the iOS 6.0 or later operating system.
