CHAPTER 2 OPERATION GUIDE
2.1 Panel operation guide
This encoder is easy to operate. It can work after connecting to input and output lines and
power. If you need to change the work environment and parameter settings, use the buttons
with the guide of menu displayed on the screen.
Attention
1. limited by the number of words shown, it could not display all menu items of the
same-level at one time. Press “↑↓”these two buttons to switch among brother menu items
in a certain order.
2. Only in the final level menu can you modify the parameters. Click "OK" button into lower
level menu when it is not the final level menu, and choose more detailed items or modify
their parameters in lower level.
3. There are many choices for entering into lower level menu from superior menu. It will
enter into the submenu item which is most recently changed or browsed.
4. Entering into the final level menu, if modification is allowed, modify the parameters and
press the "OK" to confirm. If you don't want to change the original parameters, click
"MENU" to return to the upper level.
5. When coding is in progress, on matter which menu you are at, LCD screen will
automatically go back to the main interface over certain time (5 minutes), which is the
initial status.
2.1.1 Start up
Power on to start up the encoder, it will display the uploading status:
The encoder automatically encodes after starting up, it will display a resident interface as
follows:
¾Operation

zAfter locking system, the set password takes effect, shown as follows:
zAfter locking system, when user press“MENU”button enter menu from resident

14
interface, enter password as prompt, shown as the following interface:
zIf the password is incorrect, press “OK” key to prompt that user password is incorrect,
which is shown as the following interface; press “MENU” key to switch to password input
interface.
zIf password is correct, press “OK” key to enter system menu interface, the system
unlocking in successful. After that, user press “MENU”to enter menu directly, it won’t
prompt to enter password any more. If need to lock the system again, complement
“Lock KeyBoard”menu.

15
2.1.5 Password configuration
z“Modify password” description:
zAfter complementing this menu, it will display the following interface:
zEnter “ÍÎÏДin “-”. When entering each one, the corresponding “-”will become
“*”and the cursor will move back a bit.
zPassword is defined 8 characters;
The initial password is “ÏÏÏÐÐÐÐД, it is the factory default password and can be
modified.
zWhen the cursor is in any position, press “MENU” key to quit current configuration and

Interface description
Double click EM800.exe, it will display figure 4-1：
Figure 4-1
The interface in figure 4-1 can be divided into three parts: the upper part is the available
toolbar , the left of the lower part displays the device numbers which
are connected to the network, the right of the upper part displays encoder parameters, and
the right of the lower part displays the status of encoder output interface.
In the toolbar, icon is to create a new encoder.
Icon is to open file, the opened file is the file saved in this device after user modifying
encoder parameter.
Icon is to save the modified parameter to this device.

17
Icon is the mark to log in network management software.
Icon is the refresh mark. If the device is not connected after login, press this key to find
the device which just logs in without display.
It displays the encoder number on the left of the interface. Each encoder has a corresponding
IP address and a green light.
It displays the detailed parameters which can be modified of the encoder on the right of the
interface. In the parameter list, the video bitrate cannot be modified. When setting video total
bitrate, the system will automatically generate video bitrate, other parameters can operate
according to the above system prompts. If the setting goes beyond system specified range, it
will prompt a prompt dialogbox to show how to complete modification.
It displays output status of the encoder on the right of the interface to report the encoder’s
current status: that is, whether the login is correct or not, whether there is video resource input
or not, the time of information, etc. From this window, you can obtain encoder working status
