23.1 | 9 | ANU has designed and built three generations of seismic data recorders, two of which (the small yellow TerraSAWR and the larger beige LPR-200) are still in use today. Despite their contrasting appearance, they both use the same software, data cards, and have the same instrument response. |

15.1 | 13 | = Data Card Formatting and Information = |
| 14 | |||
| |
24.1 | 15 | Both the TerraSAWR and LPR-200 require SD Cards to be formatted in FAT32 filesystem. For 64Gb cards it can be difficult to format in FAT32, but software is available (link this). ANU recommend SanDisk Extreme 150 mb/s cards in either 32 or 64Gb size. We strongly discourage using cards larger than 64Gb. |
| |
15.1 | 16 | |
| |
24.1 | 17 | The units can be "pre-programmed" with information (e.g. site name, sampling rate, etc) or they can be programmed on the fly. To program the cards you simply edit a text file (named "ANUSRSetup.txt" for the LPRs, or "tSAWRSetup.txt" for the TerraSAWRs) and place it in the root directory on the SDCard. When the logger boots up, it will parse and load this information. |
| 18 | |||
| 19 | The format for "ANUSRSetup.txt" / LPR200s will be a single line of text that looks like this: | ||
| 20 | |||
| |
25.1 | 21 | {{{XXX195G0100010034864 2 }}} |
| |
24.1 | 22 | |
| 23 | corresponding to site XXX19, | ||
| 24 | network 5G, | ||
| 25 | sample rate 0100, (e.g. 100 hz) | ||
| 26 | "gps interval" 01 (once per hour~-~- don't change), | ||
| 27 | start mode (always 0), | ||
| 28 | stop mode (always 0), | ||
| |
25.1 | 29 | seismometer type (3 = broadband (+/- 20V), 1 = shortperiod (+/- 5V), |
| |
24.1 | 30 | and seismometer serial number (4864). |
| 31 | the 2 at the very end is for "start recording on power" | ||
| |
25.1 | 32 | and is vital to have this set so the logger will resume recording on its own if it experiences a power cycle. (# of blank spaces before this doesn't matter) |
| |
24.1 | 33 | |
| 34 | the TSAWRs are a bit shorter as they don't have an option to set the "gps sync" | ||
| 35 | |||
| |
25.1 | 36 | {{{SITE1XX02500039999 2}}} |
| |
24.1 | 37 | |
| |
25.1 | 38 | which would set up a Trillium Compact with serial 9999 named XX.SITE1 at 250hz sample rate. |
| |
24.1 | 39 | |
| 40 | |||
| 41 | Here is a general guideline for how much data you can expect to fit on a card: | ||
| 42 | |||
| 43 | {{{ 64Gb card: 245 days @ 250hz or 610 days @ 100hz | ||
| 44 | 32Gb card: 122 days @ 250hz or 305 days @ 100hz}}} | ||
