S10 Serial Data Logger
S10 Data Logger Overview
The SpaceLogger S10 is a versatile serial data logger for sampling RS232 data from up to two devices.
Data is stored on a removable memory card (included), enabling remote data logging without the need for direct connection to a PC. After logging, the memory card can be simply inserted in a card reader, to view and analyse the data on a PC; no special software is required.
Each data record combines the data from the two devices or from the two samples from one device. This record is date and time-stamped when it is stored. A new file is generated for each day’s data. The default file format is .CSV; other file extensions may be specified.
To configure the SpaceLogger S10 for a wide range of devices with RS232 output, set up includes defining the start and end characters for up to two data samples, baud rate, sample rate, file name format, handling of un-printable characters, addition of a separator and/or a newline to each data record. There is also the option to disable time-stamping and data sampling (to log all data).
The SpaceLogger S10 may be set up to output RS232 data as it is input or as logged. This enables connection to a PC, display or other device. A response to a handshake may be output and/or the contents of a file on the SD card may be set to output on start-up; this enables a command to be sent to the sensor, for example.
The status of two switches to ground may also be added to each data record. The unit records data to an SD card. These cards are available with up to 2GB capacity for long term data logging (included). The SpaceLogger S10 is ideal for field data acquisition due to its low power consumption and high capacity data storage.
SpaceLogger S10 Configuration Settings
The SpaceLogger S10 is configured for different devices using file SETUP.TXT written to the SD card.
File SETUP.TXT may contain the following commands:
| WAIT | Puts SpaceLogger in ‘wait’ mode for clock synchronisation |
| TIME | Time at which clock will be synchronised |
| DATE | Date at which clock will be synchronised |
| STX | Defines the start character(s) of the first data sample to be logged |
| ETX | Defines the end character(s) of the first data sample to be logged |
| SENTENCE2 | Controls whether a second data sample is monitored for and logged |
| STX2 | Defines the start character(s) of the second data sample to be logged |
| ETX2 | Defines the end character(s) of the second data sample to be logged |
| LOGSTX | Controls whether the characters defined by STX are logged or not |
| LOGETX | Controls whether the characters defined by ETX are logged or not |
| LOGSTX2 | Controls whether the characters defined by STX2 are logged or not |
| LOGETX2 | Controls whether the characters defined by ETX2 are logged or not |
| SEPARATOR | Enables addition of a comma separator before the second data sample |
| NEWLINE | Adds <CR><LF> to end of each data sample |
| TIMEOUT | Sets a time limit within which the next ETX, STX2 or ETX2 must be detected after the first STX before the logger jumps on to await next data sample (in seconds) |
| RX2 | Enables monitoring of the second RS232 input (Input 2) |
| BAUD | Sets baud rate for RS232 data input and output |
| PARITY | Sets number of data bits and parity for RS232 input and output |
| RATE | Sets the sample rate/logging interval |
| SINGLEFILE | Sets logging to one continuous log file rather than daily files |
| FILE | Modifies file name and extension format |
| TIMESTAMP | Switches date & time stamping on or off |
| OUTPUT | Controls RS232 output of data to RS232 Output 1 |
| HANDSHAKE | Enables transmission of response string defined by RESPONSE on receipt of one of STX, ETX, STX2 or ETX2 or at a time interval defined by RATE |
| RESPONSE | Defines ASCII character string to be output on receipt of handshake string, as specified by HANDSHAKE |
| LOG_ALL | Disables sampling of data via STX and ETX commands so that all data is logged |
| RAW | Controls modification of unprintable characters (those of value <10) to <SP> characters |
| STARTUP | Controls output of file STARTUP.TXT content to RS232 Output 1 |
| SWITCH | Enables logging of status of switches on Digital I/O terminals |
| RX_INV | Controls logic inversion of the received data |
| RESET | Returns logger to default settings |
