192 +1. **Diagnostic Setup Only:**
193 +1*. Retrieves current settings for a basic diagnostic overview.
194 +1. **Seismic Application:**
195 +1*. Sets Data Output Frequency to 1000 Hz.
196 +1*. Adjusts Data Output Spatial Resolution to 2 meters.
197 +1. **Flow Monitoring:**
198 +1*. Changes Data Output Frequency to 10,000 Hz.
199 +1*. Sets Data Output Spatial Resolution to 0.25 meters.
200 +1. **Security Monitoring:**
201 +1*. Configures Data Output Frequency to 1000 Hz.
202 +1*. Sets Data Output Spatial Resolution to 2 meters.

208 +=== **Detailed Parameter Information** ===
209 +
210 +1. **Time Decimation and Output Decimation:**
211 +1*. These values are calculated based on the physical fiber length.
212 +1. **Measure Length (m):**
213 +1*. Generated value: 10176 meters.
214 +1*. Note: 'Measure Length' includes the reference fiber inside the iDAS unit, differentiating it from 'Physical Fibre Length'.
215 +1. **Pulse Width (ns):**
216 +1*. Generated value: 50 nanoseconds.
217 +1*. Spatial Extent: A 50ns pulse corresponds to a 10m spatial extent.

226 +=== **Optimal Light Management** ===
227 +
228 +* **Objective:** Achieve balanced light distribution across the region of interest in the iDAS system.
229 +
230 +=== **Adjustment Guidelines** ===
231 +
232 +1. **Setting Optical Power:**
233 +1*. Aim to have the start of the region of interest around or below +4000 units.
234 +1*. Ensure the far end of the region of interest does not enter a non-linear response scheme.
235 +1. **Consideration for Short Fibers:**
236 +1*. In cases where the fiber length is short and non-linear effects are not observed, set the Optical Power to its maximum.
237 +1*. **Power Scale:** The adjustment slider ranges from 0-100, representing the percentage of maximum power available.
238 +
239 +=== **Note on Optical Power Control** ===
240 +
241 +* **Control Mechanism:** The slider provides a precise control mechanism to manage the intensity of light sent through the fiber.
242 +* **Monitoring and Adjustment:** Continuously monitor and adjust as necessary to ensure optimal performance.

257 +== **Integrating GPS Antenna for Accurate Timing** ==
258 +
259 +=== **Installation and Connection Process** ===
260 +
261 +**Connecting the GPS Antenna:**
262 +
263 +* Connect one end of a coaxial cable with SMB female connectors to the GPS antenna.
264 +* If you plan to mount the antenna, do so before connecting the cable.
265 +* Connect the other end of the cable to the 'GPS Ant.' port located on the output panel at the front of the iDAS unit.
266 +
267 +=== **Monitoring GPS Status and Time** ===
268 +
269 +* **GPS Information Display:** The GPS status and time are displayed on the Tool Bar of the iDAS software.
270 +* **Status Indicators:**
271 +** **Red:** Antenna is not connected.
272 +** **Amber:** Antenna connected, but self-survey not completed.
273 +** **Green:** Antenna connected, self-survey completed, and timing is accurate.
