Appendix B-Operating Instructions for the AQD4-2000 Remote Telemetry Unit

1. Connect the transmit antenna to the external connector located next to the handle on the AQD4-2000 case.
   
   
2. Antenna placement is extremely important and should be placed in the highest location with a clear view of the sky. Obstructions such as buildings and large natural barriers (a sheer mountain wall) will affect the ability of the modem to acquire a satellite link.
   
   
3. The unit is equipped with internal batteries. An external power cord has been supplied to power the unit and charge the batteries. The connector is located on the right-hand side of the case. This will require a 110-volt ac power supply. When-ever possible, the external ac power should be connected to the AQD4-2000. When using the internal batteries make sure they are fully charged before placing the unit in the field. When using the internal battery, monitor the battery status from the Internet address: http://www.satguard.com/usdafs. When the internal battery is at 11 volts, the telemetry unit will need to be plugged in and the battery recharged. Connecting the AQD4-2000 to ac power and viewing the indicator on the battery charger located inside the AQD4-2000 can determine the state of charge.
   
   
4. A serial cable is supplied to connect the unit to the Data-RAM4. Connect this cable to the DataRAM4 serial port (DB 9 connector) and the four-pin connector to the AQD4 case connector located to the left of the case handle.
   
   
5. Power up DataRAM4. IMPORTANT: The DataRAM4 must be powered up and in 'run' mode before you power up the AQD4-2000 remote telemetry unit.
   
   
6. With the DataRAM4 on, verify onscreen that the unit has Version 98 (or higher) firmware and start a 'run'.
   
   
7. You are now ready to power up the AQD4-2000 unit. The power switch is located inside the case on the front left side. When the switch is in the proper position, the red light on the switch will illuminate.
   
   
8. The AQD4-2000 unit will begin automatically collecting and transmitting data.

   The following diagram shows the various states of the satellite modem and corresponds to the LED indicators located in the left-hand side of the case. The top LED will illuminate red when power is being supplied to the satellite modem and the modem has booted up. The middle LED will illuminate red when com-munication is established between the satellite modem and the DataRAM4. The bottom LED will illuminate solid green when the satellite modem has established a strong communication link with the orbiting satellite.

   

   By watching the LEDs, the user can determine that the unit is working properly. The top power-on LED should always be illuminated. The middle LED will illuminate red at the completion of each 5-minute serial measurement. The LED will stay lit for 1 minute and then turn off. The green satellite LED will be lit as long as the unit has acquired a satellite signal and established a communication link. The green LED will not illuminate when no satellite link is established, but this condition should not last more than 10 to 15 minutes. If the green satellite LED does not illuminate within 10 minutes, check that the cables are hooked up properly and that the antenna has a clear view of the satellite and is not obstructed by buildings and large trees.
