Data Acquisition Module
ADLINK's NuDAM data acquisition modules make up a total acquisition network and control system. Up to 256 NuDAM modules an be romotely controlled on any RS-485 network from a host computer, via a single serial RS-232, allowing communication from as far as 4000 feet from the host. Based on the RS-485 multi-drop network system, each module has a unique address ID, whereby simple ASCII command & response protocols through the standard RS-485 interface can control all the NuDAM modules in the RS-485 network. The NuDAM modules provide direct communications with a wide variety of sensors, perform all signal conditioning, scaling, linearization and conversion, and can acquire measurements of temperature, pressure, flow, voltage, current, and multiple digital signal types.

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.
