1. DevicePort® on Data Acquisition

With SUNIX DevicePort® Ethernet I/O Redirection Technology, traditional data collection which in the form of waveforms, on/off signals, or temperature readings have been greatly improved by the Ethernet networking feature. Ethernet allows systems to be more distributed, and remote monitoring is also possible. Here is the innovated example for centralized data acquisition solution.

A controller must be used (generally a PC or PLC) to connect to sensors and the SCADA/HMI system under traditional data acquisition infrastructure.

With SUNIX DevicePort®, data acquisition infrastructure changes from a centralized and localized system to a distributed and remotely monitored system. It also saves huge among of initial hardware investment and future maintenance cost.

The best approach in deploying a distributed Ethernet-based data acquisition system is to create a device link through daisy-chain topology that saves implementation costs such as switches, cable wiring, as well as labor costs. SUNIX DevicePort® improves deployment efficient to achieve greater reliability in commercial and industrial automation applications, such as factory automation, security and surveillance systems.

2. DevicePort® on Mobile tablet computers

The Tablet computer market share is reaching its saturation point in the consumer market, but for enterprise applications, it has just started to pick up steam; as in commercial automation solution. Tablet computers can help to enhance employee productivity and increase sales incentives for many small businesses and retail sales sectors. However, most tablet computers lag with physical I/O connectivity; additional I/O docking stations are needed to make those peripheral connections; this will eventually reducing tablet computers mobility and conveniences.

With SUNIX DevicePort®, Ethernet enabled Port Replicator, it’s easy to expand Legacy RS-232 COM and Printer LPT ports wirelessly on tablet computers. By simply connecting RJ45 Ethernet cable between SUNIX DevicePort® and WiFi Access-Point, the tablet computers will create physical COM ports automatically by using existing software application with real time data communication within the same network, and without any need for physical cable connection on your tablet computers. SUNIX will provide corresponding Application Programming Interface (API) and Dynamic-Link Library (DLL) module which allows software designers to easily develop their own programs to manipulate these serial and printing communications.
