Revision History Version Date of revision Reason for revision V1.0 Sep.21.2005 The First Edition V1.1 Oct.05.2005 Second Edition Revision Description RF EXPOSURE INFORMATION The antenna used for this transmitter must not exceed 2.5dBi and must be installed to provide a minimum separation distance of 20cm from all persons.
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. 2.

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.

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.
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.
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.
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.
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.
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.
2.5.2 Set Heartbeat Interval Type heartbeat interval in white Click “Heartbeat Interval” button. activated box. (Heartbeat Interval Range : 3 ~59 min) 2.6 How to check PPP connection and heartbeat Set heartbeat interval as 20 minutes and then change network connection status to ‘PPP Mode’.
