Radiation and Safety Requirements
Conforms to GB13837-92 & GB8898-88
Grounding Requirement
Good ground wire design is the base of the whole system, and is essential to lightning protection and anti-interference. The system must follow above principles.
Keep good electrical contact between both ends of outer conductor and shielding layer and the appearance of metal case of the connected device.
Make sure that connections of both ends of the ground wire are with good electrical contact and prepare for corrosion prevention treatment.
Do not use other device for ground wire electrical connection.
The sectional area of ground wire from rack connecting to anti-thunder unit must be greater than or equal to 25mm2
Rack Grounding
Ground terminals of racks in one room should be separately connected to protective are copper bar provided by side board. And ground wire should be as far as possible short. If the wire is too long when installing, please cut off to avoid ground wire coiling. The sectional area of guide line of ground terminal row must be greater than or equal to 25mm2.
Equipment Grounding
When grounding, use guide line to connect protective area binding post to the protective ground wire row of assembly rack.
Power Cable Connection
Power jack is on the left of rear panel, power switch is at the left side of power jack, and ground connecting screw is at the lower left side of power jack.
Connecting power cable: put one end of the cable into the AC power jack and the other (power plug) to the AC power supply.
Connecting ground wire: when connecting alone to protective area in the room, you can use independent ground or common ground with other equipments (like transmission equipment) with a resistance less than 1.
Note :
Before connecting power cable, please turn power switch to “O” position and it’s required to ground with power supply system.
Signal Line Connection
Before operating, user should connect all devices requiring cables.

NMS Operation Guide
Network Management System (NMS) can remotely set config and monitor the device. It can be used only after being authorized.
Except setting config by front panel, you can also use NMS on a PC to set and monitor device. Most of all head-end equipments (satellite receiver, encoder, multiplexer, scrambler, modulator, and adapter, etc.) can be set by NMS which is with UDP protocol and supports windows operation system.
