Data recorder


Product outline

DS252 is a data recorder that can be connected to Unipulse Weighing Indicators and Digital Indicators via SI/F Interface (2-wire type serial interface). Data of indicator can be recorded in CSV format in CF card, which will facilitate data analysis on your PC. In addition, data of various types of equipment can be printed via BCD input or RS-232C interface.


DS252 is a paperless printer that can be easily connected to unipulse weighing indicators and digital indicators via SI/F* interface. Record CSV-formatted data in CF card! Easy data analysis on your PC.

* SI/F: the standard serial interface built in Unipulse Indicators, which allows connection up to 3 external peripherals.

Mass recording in CF card

Weight/load data of indicator or DS252 statistical data can be mass-recorded in CF Card.

The data equivalent to amount of data printable on 200 rolls* of rolled paper can be recorded in 64MB CF card.

Even without a CF card, the data equivalent to amount of data printable on 1 roll* or more rolled paper can be recorded in DS252 internal memory.

* In comparison with Unipulse printer M252A (which is able to print 8000 rows on 1 roll of rolled paper)

Data recorded in CSV format

Data can be recorded in the easy-to-handle CSV format and can be editable as it is using Microsoft Excel or other applications.

Code-table function

DS252 has been pre-set with a 2-digit number to each of its code type. This function allows the code to be registered in the pre-set code by entering only the pre-set 2-digit number either using the front panel key or via an option. The code can use alphanumeric characters, katakana and/or symbols for up to 6 characters or digits. Up to 100 codes can be classified and tailed in each channel.

High-level statistical calculation functions

DS252 is pre-loaded with a function that calculates grand total, sub-total, maximum, minimum, average or standard deviation of the recorded data. At the same time, DS252 is able to grasp the extent of data variation using its frequency distribution function.

Simple operation & code-table registration via PC

・As setting items are displayed on the LCD panel, setting can be easily done using the front panel key while viewing the display.

・DS252 codes can be saved in the CF Card. And reversely, codes saved in the CF Card can be written in DS252 internal memory. As this bothersome code registration process can also be done on a PC, the operation is very convenient indeed.

Optional interfaces

Basically, SI/F interfaces are installed in 2 channels to enable economical double channel recordings. However, as option interfaces, there are RS-232C and BCD input interfaces available. With that, data from various kinds of devices can be recorded.

By entering via the front panel key, weight data with code can be recorded in both Ach and Bch. Names of each part code data of Ach can also be entered via an optional interface.
