Overview

The SM4M was only compatible with our mixed-array data loggers and the DSP4 Heads Up Display. (See the Compatibility information.) It used non-volatile Flash EEPROM memory to store two million low-resolution data points (the SM16M stored eight million).

Technical Description

The SM4M was only compatible with our mixed-array data loggers and the DSP4 Heads Up Display. (See the Compatibility information.) It used non-volatile Flash EEPROM memory to store two million low-resolution data points (the SM16M stored eight million).

The SM4M was used to augment on-site data storage, and to transport data or programs between the data logger and computer. It had a sealed canister housing fitted with a single, 9-pin D-connector. LEDs indicated when data transfer was active.

The SM4M's internal memory could store both data and programs. The memory was split into 64 kbyte blocks.

The SM4M was previously ordered as p/n 10820.

Compatibility

Computer Interface

The SC532A Interface was typically used to connect the storage module to a computer.

Data Logger Considerations

The SM4M is compatible with mixed-array data loggers. It is not compatible with data loggers that store data in a table-based format.

Data Logger Interface

The SM4M connected to a mixed-array data logger via an SC12 9-pin cable.
