Firmware for High-speed Communication
OP-FW12GA
OP-FW12GA is the firmware to increase the speed of monitoring test of bit synchronous communication (such as HDLC/SDLC/X.25, or CC-Link communication), SPI communication, Profibus-DP (field bus known for high-speed communication), UART (asynchronous communication, which is commonly used). By processing great part of monitoring processes by FPGA, it unfailingly captures communication data with time stamps of a microsecond rate. The interface supports RS-232C/RS-422/RS-485/TTL.

Signal Converters
On one hand, there are signal converters which transform an input frequency range into an analog signal. These signal converters are very easy to program and control. Other signal converters can transform analog input signals into analog normalized signals with galvanic insulation. Due to the fact that these signal converters can be freely graduated, they offer endless possibilities and 110 combinations can be selected by means of a DIP switch. Other kinds of signal converters can be connected to devices with RS-232, RS-485 or RS-422 protocols.

Compact Protocol Analyzer
LE-1500R
"LE-1500R" is a protocol analyzer (line monitor) dedicated for asynchronous communication monitoring with affordable pricing. LE-1500R can run as a stand- alone by the internal battery for long time and can be remotely controled by a PC or a smart phone via Wi-Fi (Wi-Fi function is available only in USA, Canada, Japan, and EU). The analyzer has a TTL measurement port (which supports UART communication) as its standard port besides RS-232C, RS-422, and RS-485. It can monitor communication data of max 500Kbps for up to 32MB (8,000,000 data) in real time and also can execute a simulation testing of send/receive data. It also has a BERT function (which is not equipped with the analyzers of this pricing level) as its standard function. The correct time stamp, the measurement of idel time (which are the difficult for other software analyzers), and the capturing ability (without missing data) are the best options for trouble shooting and development test of a communication sytem which requires a reliablity.
