1. Overview
HB(Heart Beat)1900 is designed for the purpose of checking the repeater systems which were
installed in Sprint network.
Using CDMA 1x modem protocol, heartbeat is happened only when the repeater system
operates correctly. It traces the repeater status and give heartbeat signal periodically to WNMC
server through SNMP Trap.

The SNMP Board located in the HB 1900 cabinet which is the essential of the HB 1900.
The SNMP board contains powerful microprocessors.
Operational parameters, such as Heartbeat interval, Modem Attenuation, SNMP version, Site ID,
etc. are set using a desktop or notebook and OMT, which communicate, locally via RS-232C
cable, with the RRMS. Remote operation is performed via CDMA net

4. Installation
4.1 How to install Program File
GUI program consists of one exe file. Therefore, you can copy one exe file to your PC and use it.
R-TRON Proprietary & Confidential
Page 10
4.2 Connect communication cable
Connect communication cable as followings,
4.3 Power on
After connecting the communication cable, you can supply AC power to the HB 1900. As you
can see the following picture, when you supply AC power to the HB 1900, the DC 5V LED light
up one time. After 3 or 4 seconds later, the modem power(3.3Voltage) LED light up two times.
Then 10 seconds later, the LED light three times. This signals that the heartbeat unit is ready for
communication. Finally, you can execute GUI program and get the heartbeat communication
started.
4.4 How to start GUI Program
Click HB 1900 v1_2.exe.
R-TRON Proprietary & Confidential
Page 11
When you click HB 1900 v1_2.exe, you will see the following pop-up window.
4.5 How to use and configure the Graphic User Interface (GUI)
4.5.1 Login / Logout
To proceed using the GUI Program, a user should log-in.
There are two kinds of users. One is the‘root’ and the other is the‘operator’. The ‘root’ user, the
can control all GUI buttons but the ‘operator’, can not use debugging pop-up window. Input
classified user IDs(‘root’ or ‘operator’) and assess password. After that,all default buttons will be
activated.
4.6 How to set up a communication port
After setting up the GUI Login, you should set up the communication port between the system
R-TRON Proprietary & Confidential
Page 12
and GUI. The Communication protocol is a RS-232C protocol between the SNMP board and the
PC serial port which is set up by the GUI. The Current RCU transmit speed is fixed at
11,5200bps. As you can see in the above picture, you can select the proper COM port and then
click the ‘START’ button. Now the RCU communication is started. If there is no problem with the
communication, the Rx LED will light up green with the Tx and Rx lighting up green, alternately.
4.7 Check setting figures
As shown in the above picture, you can check the Site ID(Cascade Code) , WNMC Phone
Number , WNMC IP Address , SNMP Version and Modem Phone Number. When you change
the current GUI settings, you can input the needed numbers in the white boxes and click toggle
switch to store the values.
4.7.1 How to set Parameter value
4.7.1.1 Cascade code Input
ex) Cascade Code which is given by a wireless operator : test01
Type Cascade code in white activated box.
R-TRON Proprietary & Confidential
Click “SiteID Set” button.

4.7.1.2 Input WNMC Phone Number
Sprint WNMC Phone Number is #777 and procedures is as followings,
Type “#777” in white activated box
Click “Phone Number Set” button
4.7.1.3 WNMC IP Address입력
Sprint WNMC Server IP Address는 10.22.25.15 and procedures is as followings,
Type “10.22.25.15” in white activated box.
R-TRON Proprietary & Confidential
Click “IP Address Set” button.
Page 14
4.7.1.4 Input Modem Phone Number
Type modem phone number which you are going to put it into HB 1900.
Each modem phone number is different.
For example, when it comes to modem phone
Click “Modem NUM Set”
number is 5022759735, type this number
in white activated box.
2.4 How to check Modem
You can set the network connection status in ‘modem mode’ using the modem status pop-up
window and entering information in the ‘modem statistics’ pop-up window as followings,
R-TRON Proprietary & Confidential
Page 15
①
When the Modem is properly connected, you will see ‘READY’ im green, like in the
above picture[number 1].
②
Then you can click the NMST button [number 2] and test the AT Command. When
you see the ‘OK’ response, this means that the modem and SNMP board status is
Okay.
2.5 Check RSSI Value and Set Attenuation
2.5.1 Set Attenuation
After check the RSSI value which is displayed on the GUI, set the RSSI value as -70dBm, using
the modem attenuation. For example, when the GUI RSSI value is -67dBm, you can set it as 70dBm, using the modem attenuation 3dB. To set the attenuation, you can input the attenuation
value in white box and then click the ‘modem atten’ button which is located on the left side to
store it. (Ex-factory setting value of HB 1900 : user attenuation is 12dB , Heartbeat interval is
5 minutes.)
