Communication Flexibility
Communication media between the remote stations and
master station include:
1. VHF/UHF radio communication link
2. PSTN dial-up line
3. PSTN leased line
4. GSM MODEM / SMS
5. Inmarsat-C Land Mobile
6. Receive data email through ORBCOMM ‘s Low orbiting satellite
7. Export real time data in email format every hour for web publishing

Multiple Protocol Support
The SM2000 master station communicates with it’s remote stations through a rich set of standard protocols (telemetry protocol, industrial standard MODBUS ASCII or RTU, HDLC, X3.28), transparent to the physical communication links used. For communication with any SCADA software which runs on a MMI, it uses a rich set of standard protocols (telemetry protocol, industrial standard MODBUS ASCII or RTU protocol) via a dial-up link or direct RS232C .

User Friendly Interface
Standard keyboard & large screen LCD is provided for the database viewing and entry purposes.
Real-time display of telemetry data is made easy on SM2000 that uses a powerful 32bit-computer
platform. The following shows user settable parameter from the master station:

Local System parameter
• Set maximum RTU number
• Set Network address
• Set system date and time (master clock)
• Set scanning rate (from 15 min.. 24 hours)
• Set flood mode / normal mode
• Set automatic scanning reference time
• Set FEP-RTU time synchronisation interval
• Set number of retry and interval between retry after radio-link failure

Remote Setting Of RTUs’ parameters
• Set and retrieve rainfall base level (set to anyvalue within 0-9999mm)
• Set scalar and offset for analogue sensors(for 5m, 10m, 20m .. )
• Set river-bed sea level offset (i.e. 0 m water depth is 22.7m )
• Set and retrieve RTU auto-dump interval
• Start/Stop RTU data logging facilities
• Set and retrieve RTU data logging interval

Local Communication parameters
• Set RTU communication media (RADIO, MODEM, ORBCOMM etc.)
• Set RTU Store-And-Forward (SAF) repeater path (for Radio System Only)
• Set RTU phone number (if PSTN modem is used as communication device)
• Set RTU repeater (store and forward facilities in Radio System)
• Change communication baud rate (1200 or 300Bps for Radio System)

View Database
• View latest remote stations’ water level
• View latest remote stations’ rainfall
• View latest remote stations’ water quality
• View latest remote stations’ daily rainfall
• View remote stations’ data base on user specified date/time interval
• View status of telemetry data (Valid/Error/Communication error)
• View alarm status of telemetry data (alert/warning/danger)
• View remote stations’ battery level

Auto/Manual Calling RTU
• Accept RTU automatic send exception data/alarm
• Settable Interval Automatic Scanning all RTU (with individual Scanning rate)
• User/ Adhoc call single RTU
• User/ Adhoc call all RTUs / Manual Scaning

Supervisory Control
The SM2000 can accept various output commands from the MMI computer to affect supervisory controls function in form of analogue output, digital/relay output. In SCADA application, local output points in FEP or remote output points in RTUs can be controlled by MMI computer running any SCADA software.

Alarm Management
User may configure a set of alarm level /threshold values in the FEP database for alarm monitoring purposes. When alarm signal is detected, the alarm manager inserts an alarm record into the buffer with a real time stamp and an option to print out alarm message. The parameters included are: Alert level, Warning level, Danger level, Minimum reasonable Level (For data validity checking), Maximum reasonable Level (For data validity checking), Alarm masking facilities for station
