FIGURE 1-1. Storage Module and SC12 Cable
1.2 Physical Description
The Storage Module is housed in a sealed canister with a single, 9-pin D-
connector. The Storage Module is connected to a datalogger via the SC12 9-
conductor ribbon cable.
There are two LEDs (light emitting diodes) adjacent to the connector. A red,
status LED indicates the operational status of the module at power-up (see
section 1.4.7) and a green LED lights when data is being stored in the module.
