1. Product Introduction

1.1 Overview

TBS8112 is a compact trans-modulation device that is used to convert free DVB-S/S2/S2X satellite TV

channels to DVB-T (Digital Terrestrial Television) format. It supports to receive free satellite channels from 4

frequencies via 4 RF port, and output DVB-T channels in 4 frequencies.

To meet customers’ various requirements, TBS8112 DVB-S/S2/S2X to DVB-T trans-modulator also support IP

streams input and local video file storage. With “Remux” technology, you can randomly select required

channels from input streams or local video files, then multiplexed to a new TS stream and output in 4 DVB-T

Frequencies.

TBS8112 DVB-S/S2/S2X to DVB-T trans-modulator supports NMS system, can be controlled and configured via

Ethernet using a standard browser.

2. System Connection and Log in

➢The default IP for TBS8112 DVB-S/S2/S2X to DVB-T trans-modulator is 192.168.8.101:8081.

➢In first place, check the IP address of the PC. It must be in the same IP range of the device. This means, an

IP like 192.168.8.xxx (xxx can be 0 to 255 except 101 to avoid conflict with module IP address). Add a new

IP or change the current one to meet this requirement.

➢Check connections. The Ethernet cable must be connected to the LAN port (see description chapter). It is

recommended to try a ping on the command-line interface to confirm they are on the same network

range and communication between them is possible.

➢Now use a web browser to run the webserver application from the PC. Write the IP address (by default

192.168.8.101) on the URL bar and press ENTER.

➢If connection is successful, the browser will display a login screen (see description chapter). Enter the

Username and Password (by default both are “root”) then click on ‘Login’ to enter the webserver

application.

NOTE: After communication is established, the user can set a new User name and Password.

The default ID: root

The default password: root
