2.2.3 Operation of local mode

We take an example in the next section to show how to use OMT, which attached Channel selective repeater in

local mode.

a) User shall have a RS232 cable to connect repeater with the computer. If the computer isn’t outfit a serial

port, user can use a USB-to-Serial cable for this purpose.

Main window is as the following:


Tel: +86 10 80481995 Fax: +86 10 80482438


Get one by one

Figure 14

b) There are two tabs in the main window: ‘Basic INFO’ and ‘Engineering parameter’. User can click the

title to switch tab.

‘Engineering parameter’ Tab:

Only 2 types of actions can be performed: ‘Get’ and ‘Set’.

Get: Click ‘Get’ button to query the value from the repeater.

Set: Not all parameters for repeater can be modified. A ‘Set’ checkbox follows a parameter which user

can modify. Check the checkbox, and input value into the textbox, then click ‘Set’ button to modify the

parameter.


Tel: +86 10 80481995 Fax: +86 10 80482438


Figure 15

c) The ‘Basic INFO’ tab is used as following:

i. Click ‘Get’ button to query the respective parameters. As figure 14. User can click ‘Get All’ button on the

bottom of the window the get all parameters from the repeater while OMT send multiple query command to it.

As Figure 16.

iii. Setting Parameters. For example, set the value for gain in uplink and downlink:

As Figure 17, repeater maximum gain is 88dB. The gain is set to 70 dB (Deduct 18 dB attenuation from

88 dB). To set the gain to 80 dB, as following:

Check ‘Set’ checkbox next to Uplink/downlink attenuation value. Then input the value in the attenuation

textbox, as the following figure:

Figure 18

Input 8 into uplink/downlink attenuation textbox, as the following figure:


Tel: +86 10 80481995 Fax: +86 10 80482438


Figure 19

After inputting the value, click ‘Update’ button on the bottom of the window. As the following figure:

Figure 20

When the setting is applied successfully, OMT will popup an information window. As following:


Tel: +86 10 80481995 Fax: +86 10 80482438


Figure 21

It indicates setting ATTN value successfully. Otherwise, it will prompt the dialog box indicate the

operation failed.

Notice: when user input the wrong ID to connect repeater, all operation will be failed. System will

prompt error message as following:

Figure 22

To work with the repeater, user can set the ‘Repeater Id’ and ‘Device Id’ same as the repeater connection

setting (Figure 10). As Figure 23:

Figure 23

iv. Other operations are same.

2.2.4 Operation of SMS mode

As Figure 13, once using ‘SMS’ mode to connect repeater, user shall connect the computer with the cellular

phone or wireless modem. User also need set the communication parameters for remote connection. Please

check the previous section ‘serial port setting for remote connection’ for the relevant instruction. Other

operations are same as Local mode. But remote connection will result in slow response for every command. In


Tel: +86 10 80481995 Fax: +86 10 80482438


ordinary circumstance, it takes between 30 and 60 seconds for the repeater to respond a command. So user

shall commit ‘Get’ and ‘Set’ action one by one to improve response speed.

The message window will indicate short message sent successfully when the command is executed

successfully. As Figure 24:

Figure 24

2.2.5 Operation of SMS mode

Data mode is similar with SMS mode. Data mode requires the computer connect with cellular phone or

wireless modem. It also requires remote connection setting. Committing ‘Get’ and ‘Set’ action one by one is

also recommended to improve response speed.

The difference between Data mode and SMS mode is: in ‘Data mode’, after clicking ‘connect’ button, OMT

will dial up immediately. As the following figure:

Figure 25

After being connected successfully, the main window shows.

a) Using dial up, connection is difficult to setup and data communication is slow and unreliable. User can

click the ‘Dial up’ button in the toolbar to redial when the dialup connection is disconnected. As the following

figure:

Figure 26

b) User can click ‘Hang up’ button to hang up the connection. As the following figure:


Tel: +86 10 80481995 Fax: +86 10 80482438


Figure 27

c) User can click button to force disconnecting when the system has no response to ‘hang up’ command. As

the following figure:

Figure 28

d) Disconnecting

User can click ‘Disconnect’ menu or the button ‘Disconnect’ in the toolbar to disconnect the dialup connection

and close the repeater information window. As the following figure:

Figure 29

2.3 Advanced Settings

The menu has the following functions:

Figure 30

a) Software downloading:

Figure 32

A message box will pop up after downloading successfully. Then repeater reboot.

b) CPU reset

Click ‘CPU Reset’ button to reboot repeater. The function is similar ‘Reset’ button on PC.

c) Repeater Clock

Figure 33

It is convenient for user to lookup and to update the repeater clock on the dialog box.

d) History Alarm

User can view the history alarm kept on the repeater. As the following figure:


Tel: +86 10 80481995 Fax: +86 10 80482438


Figure 34

Click ‘Delete’ button to delete the history alarms in the repeater.

2.4 Help

Click ‘help’ to open user guide.

2.5 Notes for remote communication

a) The system has 2 modes for remote communication: SMS mode or Data mode. System couldn’t transfer

from one mode to another automatically. User can send command to switch the working mode. Working with

local mode, user can switch arbitrarily. However, in remote mode, user shall know which mode he/she working

with. Then he/she use command to switch the system from one to another. For example, user works in SMS

mode. He/she shall use OMT to send a SMS command to switch the working mode to data mode. Repeater

receives the SMS. If repeater accept the command, it reply a successful setting SMS. After the message is sent

successfully, repeater is switched to data mode. Then, user shall use data mode to query and set parameters in

the repeater.

b) To remotely control, the specified phone number shall be same as ‘MOC Query/Control phone NO.’

Otherwise, user can’t set parameter but query parameter in the repeater. As the following figure:


Tel: +86 10 80481995 Fax: +86 10 80482438


Figure 35

c) In SMS mode, ‘SMSC phone No.’ in ‘Engineering Parameter’ tab must be specified correctly. Otherwise

repeater can’t work., As the following figure:

Figure 36

d) In data mode, OMT software has 1 minute timing protection on the packages sent out. When data

connection is established, we suggest user wait about 20 seconds to execute commands against repeater. If the

system has no response, user shall wait more than 1 minute for OMT.

e) For closed repeater, user shall reset cut the power supply of the repeater after inserting SIM card.

Thank you very much for your support!
