ZEROPLUS Technology has released two types of Protocol Analyzers, LPT and DALI, at present. Until now, ZEROPLUS Technology has developed more than 50 kinds of Protocol Analyzers, which are used in many fields, such as PC System, Digital Multimedia, Memory, and so on. R&D persons can download many kinds of Protocol Analyzers according to their requirements, which can accelerate the speed of the development and simplify the flow of the development. Protocol Analyzer DALI (Digital Addressable Lighting Interface) is used for controlling the LED Lighting System. So the working efficiency of lighting devices can be improved with the help of Protocol Analyzer DALI. Protocol Analyzer DALI utilizes the master-to-slave structure, and each DALI system can connect with a maximum of 64 devices. Generally, the transmission speed of the common DALI is approximately 1.2K BPS, and the DALI uses the Manchester Encoding to transmit data on the aspect of data transmission. In a word, according to the control of Protocol Analyzer DALI, the working efficiency of lighting devices can be improved. ZEROPLUS Technology Protocol Analyzer DALI can analyze START, ADDRESS, COMMAND, DATA and STOP in the DALI signal. As the DALI adopts two lines and the Differential Mode to transmit data, the present connected signal can be set whether to activate the Reverse Decoding function in the ZEROPLUS Technology Protocol Analyzer DALI, and whether the value of the Baud Rate in the signal is judged by the Protocol Analyzer automatically, which can improve the working efficiency of the development and save a lot of time which is spent to decode signals manually. LPT (Line Print Terminal) is mainly used in computer peripherals, such as the Printer, Scanner or Modem and so on. And it utilizes the DB-25 Connector. Generally speaking, LPT has the following Working Modes: 1. SPP (Standard Parallel Port) Working Mode; 2. EPP (Enhanced Parallel Port) Working Mode; 3. ECP (Extended Capabilities Port) Working Mode; 4. BI–DIRECTION. However, in the four modes, the SPP Mode is the most widely used mode. Specifically, LPT is mainly used in the early PC System. It is used to connect the computer peripherals, such as the Printer, Scanner and so on. The connector of the LPT is DB-25 (25PIN). And LPT can support many kinds of working modes. ZEROPLUS Technology Protocol Analyzer LPT can analyze WRITE, READ, ACK, PAPER END, UNSELECT, AUTOFEED, INITIAL, INTERRUPT, ECP ACTIV, FORWARD, REVERSE and STOP in the LPT signal. Users can set the working mode for the present connected LPT signal in the ZEROPLUS Technology Protocol Analyzer LPT, so that users can use the Protocol Analyzer LPT more flexible when developing products. What’s more, Protocol Analyzer LPT can analyze all the signals of the different LPT modes smoothly.

Zeroplus Technology focuses on the design of the peripheral products of computer games. In 2004, the business scope was extended to the electronic measurement instruments. Applying the advanced MCU programming technology, the company successfully developed the latest patented measurement instrument, PC-Based Logic Analyzer. The unique and innovative technology was accredited by a number of patents granted, and the regions or countries where the company applied for patents have covered all over the world and the number of the patent and the country continues to grow. Since the release in 2005, the Logic Analyzer has been widely adopted by tens of dozens of public-listed technological manufacturers in the IC industry and the tertiary educational institutions. The excellent sale has made the Logic Analyzer the most popular in the market.
