Chapter 3 Installation Guide
3.1 Acquisition Check
When user opens the package of the device, it is necessary to check items according to packing
list. Normally it should include the following items:
DX3316 IP QAM Modulator
User‟s Manual
Power Cord
If any item is missing or mismatching with the list above, please contact local dealer.
3.2 Installation Preparation
When users install device, please follow the below steps. The details of installation will be
described at the rest part of this chapter. Users can also refer rear panel chart during the
installation.
The main steps of the installation include:
Checking the possible device missing or damage during the transportation
Preparing relevant environment for installation
Installing DX3316 IP Mux-Scrambling QAM Modulator
Connecting signal cables
Connecting communication port (if it is necessary)

3.2.3 Grounding Requirement
All function modules‟ good grounding is the basis of reliability and stability of devices.
Also, they are the most important guarantee of lightning arresting and interference
rejection. Therefore, the system must follow this rule.
Coaxial cables‟ outer conductor and isolation layer should keep proper electric conducting
Item
Requirement

with the metal housing of device.
Grounding conductor must adopt copper conductor in order to reduce high frequency
impedance, and the grounding wire must be as thick and short as possible.
Users should make sure the 2 ends of grounding wire well electric conducted and be
antirust.
It is prohibited to use any other device as part of grounding electric circuit
The area of the conduction between grounding wire and device‟s frame should be no less
than 25mm2.
3.2.4 Frame Grounding
All the machine frames should be connected with protective copper strip. The grounding wire
should be as short as possible and avoid circling. The area of the conduction between
grounding wire and grounding strip should be no less than 25mm2.
3.2.5 Device Grounding
Connecting the device‟s grounding rod to frame‟s grounding pole with copper wire.
3.3 Wire’s Connection
3.3.1 Power cord connection
The power socket is located on the right of rear panel, and the power switch is on the left of
front panel. User can plug one end of the power cord to the socket and insert the other end to
AC power. When the device solely connects to protective ground, it should adopt independent
way, say, share the same ground with other devices. When the device adopts united way, the
grounding resistance should be smaller than 1Ω.
Caution: Before connecting power cord to DX3316 IP QAM Modulator, user should set the
power switch to “OFF”.
3.3.2 Signal and NMS Cable Connection
The signal connections include the connection of input signal cable and the connection of output
signal cable.
