effigis.com 1. General Information 1.1 About this Manual This manual describes the components, installation and operation of the CPAT FLEX DSG1 unit. You will find important safety information in this manual. We strongly recommend that all users read this manual. Use of this product other than for its intended application may compromise the unit’s safety features. 1.2 Explanation of Symbols Used The following symbols are used in this Manual: Symbol Explanation ! Caution.
NOTE This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy, and if it is not installed and used in accordance with the instruction manual, it may cause harmful interference to radio communications.
effigis.com 2. System Components 2.1 Product Overview This section describes the DSG1 unit, including its accessories. The DSG1 is a dual-band signal generator that inserts an ultra-low level signal between quadrature amplitude modulation (QAM) channels, without causing interference or MER degradation. The DSG1 can be operated simultaneously in both aeronautical and LTE bands using two separated RF outputs.
Figure 1: DSG1, rack mount brackets and AC/DC adapter If any of the standard accessories are lost or damaged, you can order a replacement for the DSG1. Please quote the following part numbers when placing an order: Part No.
effigis.com 3. Installation This section describes how to install the DSG1. You may also refer to the installation diagram at the end of this manual. 3.1 Mounting the DSG1 in an Equipment Rack CAUTION! Leave space for front, back and lateral ventilation. 3.2 Connecting RF Outputs The RF outputs should be connected directly into the cable network’s RF forward combiners.
3.3 Electrical Installation The AC/DC adapter is supplied with the equipment. It is compatible with 110V/220V and 50/60 Hz power distribution networks. 3.4 Internet Connection (optional) The DSG1 can utilize an Internet connection to read operating parameters from the CPAT servers and to update firmware automatically. The Internet connection might also be useful for remote diagnostics, if needed. When connected, the unit checks for new parameters or updates every 5 minutes.
effigis.com 4. Setup CAUTION! Any changes to the setup of the DSG1 carriers must also be made to the DRV3 receivers deployed on the field. Using different parameters will prevent the leakage detection from working as intended.
4.2 Set Parameters Remotely You can set the DSG1 operating parameters by remote through the CPAT web application. It stores active parameters in its database and stores a copy in a text file that can be downloaded automatically by the DSG1. 4.2.1 FTP connection Once step “3.4 Internet Connection” has been completed, make sure that the unit has access to the Internet and that FTP port 21 is open. This is required in order for the DSG1 to communicate with the CPAT FTP server. 4.2.
effigis.com 4.3.3 Using the DSG1 settings applications At startup, the DSG1 settings application displays a “DSG1” button. When you click it, the application starts looking for all DSG1 units connected on the network. If several DSG1 units are found, the first DSG1 found is selected by default. To select a different DSG1, choose another DSG1 from the dropdown menu next to the “DSG1” button. If no DSG1 units are found, the system displays a special message (“No DSG1 found on the network”).
When a DSG1 is selected, the currently applied settings are summarized in the “Monitoring” panel. All “Lab volatile settings” functions become available for modification, if necessary. You can edit the attenuation, frequency and level of both bands within the allowed limits. However, since these settings are volatile, any changes will be lost after a reboot of the DSG1, and the default settings will be applied until you edit them again.
effigis.com After the first successful Export, an “Import” button becomes available in the “DSG1 Permanent local settings”. The Import function applies the DSG1’s editable default settings (startup frequency, mode and level for each band, transmission activation and startup PRN). These settings are effective immediately, and they become the new default settings for the next startup. NOTE The DSG1 will always try to connect to the CPAT FTP server.
5. System Operation 5.1 Power On To power on the unit, make sure that the power cable is properly connected to a surgeprotected outlet (recommended) and to the DSG1. Press the ON/OFF button on the front panel for 3 seconds, and then release it. You should see both lights on the front panel turn green, and then the PWR light will turn red. 5.2 LED and LCD Information The two front LEDs indicate the status of the unit. PWR (power): • When steadily lit RED, the system is booting (takes about 1 minute to boot).
effigis.com 5.4 Shutdown There are two ways to power off the unit: Normal and Force Shutdown. The preferred mode is Normal shutdown to avoid undesired flash memory corruption. The Force Shutdown function should be used ONLY if the device is not responding. 5.4.1 Normal Shutdown: In normal running mode, press the front panel ON/OFF push button for 1 second then let the DSG1 shut down each process properly. A message will then appear on the front LCD screen, and the device will turn off. 5.4.
6. System Maintenance 6.1 Cleaning the Equipment Your DSG1 unit can be wiped clean with a damp cloth. Do not immerse the unit in water. Avoid solvents and commercial cleaners. 6.2 Preventive Maintenance The technician shall perform periodic visual inspections on the RF connections to make sure that there is nothing loose or broken which could affect the performance of the system. If any replacement parts are required, please contact Effigis for more information. 7.
