DSG1 Installation & Configuration
Step 1 - Installation
1. Make sure no items are missing. Your DSG1 kit should include:
• DSG1 rack mount unit.
• 2 Rack mount right angle brackets.
• AC/DC adapter.
• Operation manual.
2. Install the DSG1 unit in a rack mount
CAUTION!: Leave space for front, back and lateral ventilation.
3. Connect the RF Outputs.
• The RF outputs should be connected directly into the cable network's RF forward combiners.
• Suggested F connector tightening torque is 10 inch-pounds. Maximum torque is 15 inch-pounds.
• Do not leave any RF outputs unterminated. If one of the outputs is not connected to the network, put a 75 Ohm F terminator on the output.
CAUTION!: In order to avoid unwanted interference with the QAMs in the cable network, first set up the frequencies and output levels as described in the table in Step 2 before connecting the RF outputs.
4. Electrical installation
5. Connect the DSG1 to the internet (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. Transfers amount to a few hundred kilobytes per day.
To ensure that the DSG1 can communicate with the CPAT FTP server and obtain its parameters and update files, you must have the following:
• DHCP enabled on the network:
The DSG1's IPv4 address is acquired through dynamic host configuration protocol (DHCP). If
no DHCP server is present on the network, the system will not be able to transmit data over
the network.
• FTP port 21 must be open:
Make sure the unit can access the Internet and that file transfer protocol (FTP) port 21 is
open. Without this access, the unit will not be able to communicate with the CPAT FTP server
nor download its parameters and update files.
