Detailed Description

The SM4M was only compatible with our mixed-array dataloggers 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 datalogger 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.

Additional Compatibility Information

Computer Interface

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

Datalogger Considerations

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

Datalogger Interface

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