8 Min-/max-value memory
The device features a minimum/maximum-value storage. In this storage the highest and lowest performance data is
saved.
Calling of the minimum value:
Press button 3 shortly: the device will display “Lo“ briefly, after that the min-value is displayed for about 2 sec.
Calling of the maximum value:
Press button 2 shortly: the device will display “Hi“ briefly, after that the max-value is displayed for about 2 sec.
Erasing of the min/max values:
Press button 2 and 3 for 2 sec.: The device will display “CLr“ briefly, after that the min/max-values are set to the cur-
rent displayed value.
9 Serial interface
The device features one EASYBus-Interface. You can use the device as a full function EASYBus-device.
The serial interface allows the device to communicate with a host computer. Data polling and data transfer is done in
master/slave mode, so the device will only send data on demand. Every device has a unique ID-number that makes
exact identification of each device possible.
With the help of a software (like EASYBus-Configurator – freeware version available via internet) you are able to
reassign an address to the device.
Additional accessories needed for the interface mode:
- Interface Converter EASYBUS  PC: e.g. EBW 1, EBW 3, EBW 64, EBW 240 and EB 2000 MC
- Software for communication with the device
EBS 20M / 60M: 20- or 60-channel-software for displaying a measured value
EASYControl net: multi-channel software for real-time-recording and displaying measure-values.
EASYBus-DLL: EASYBus-developer-package for developing own software. This package features a universal
WINDOWS®-Library with documentation and program-examples. The DLL can be used in any
usual programming language.
