The Berthold Technologies 9111 data-logger is a counting electronics of modular design primarily intended for use in remote monitoring locations thanks to its low power consumption, the permanent solid state memory, computer and tele-communication link.

Each device may contain up to 6 independent multi -detector channels, for example two mono detector dose rate channels and one dual detector environmental channel. When there is a need for more than 6 channels several devices may be combined to one system, sharing a common communication link.

Measurements are carried out based on a real time rate meter algorithm, assuring accurate results and fast reaction times. Results are buffered permanently, until they are retrieved locally or remotely. Measurement data can also be directed to analogue outputs, for direct connection to analogue displays and chart recorders.

Special events such as alarm or failure conditions, trigger latched and non-latched on/off outputs, driving audio-visual indicators and long signal wires. Occurrence of any special event is also recorded in memory.

Working parameters reside in permanent memory and may be accessed and changed either locally or remotely.

Local access is possible via a built-in display and keyboard. It is based on plain text dialogues, assuring natural and consistent parameter entry and data retrieval. A software password prevents unauthorized access.

Remote access via a serial port is based on a flexible, yet easy to use ASCII (F²C) protocol. In order to be compatible with various existing communication techniques, the system can be equipped with a converter. (leased lines, public telephone, X25, ISDN, etc..)

The radiological channel type assignments and the language of dialogue messages are contained in solid state memory resident resources, that are not part of the firmware code. By this approach it is feasible to conceive instruments serving different applications simultaneously. In most practical cases, the number of channels remains rather limited and combined applications will be logically related.
