226 +=== **Optimal Light Management** ===

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.
