1. Batteries Frequently asked questions How can I check the GSM signal on a proposed site Isodaq can provide GSM survey equipment for sale or hire or can add survey capability to existing Isodaq loggers Can a Frog RX transfer data to SCADA systems If the SCADA system supports the DNP3 protocol then most likely the answer is YES A number of SCADA vendors are already supported via DNP3 and we are keen to help support more Please contact us to discuss your requirement 3 3 Sensors What sensors does the Frog RX support Refer to the sensor list on page 12 How do configure a Frog RX for a particular sensor The free Harvest software is used to configure the Frog RX for specific sensors See page 75 If you order sensors via Isodaq or free issue them with your order we can supply systems pre configured How often does Frog RX take a measurement The Frog RX can be configured to sample at intervals ranging from 10s to 12h Typically intervals of 5m or 15m are used See list of storage intervals in the specification on page 36 Does the Frog RX provide power for sensors The Frog RX can be configured to provide switched 12V power for sensors Loop powered sensors must operate correctly at 11V Warm up time can be set to allow the reading to stabilize 3 4 Batteries What sort of batteries does the Frog RX use Internally the Frog RX can have either an Alkaline or a Lithium battery pack The Lithium pack is m

GPRS data collection uses no modem at the receiving end Data comes in directly over the internet the Frog RX dials out to a URL a web address Setting up a web address to receive GPRS calls requires IT expertise and depends on the network configuration at the organization hosting the data collector Unless fixed IP SIMS are used only check in mode logger originated calls see below is supported for GPRS Loggers can still be polled via Harvest and a modem if the CSD data number of the SIM is known 10 3 Polling or check in There are two methods of retrieving data from telemetry loggers e Polling where the data collector originates calls to outstations Page 61 of 84 Modem power management Telemetry introduction e Check in where the outstation originates calls to the data collector Polling has advantages where the logger must be contacted by the data collector on demand Check in has advantages of lower power consumption and of daily test of poten tially critical alarm calls Isodaq Telemetry Loggers support both methods although check in is generally preferred for reasons outlined in the following sections 10 4 Modem power management GSM GPRS modems use significant power when they are left switched on so the logger can receive calls Power is mainly consumed by the radio receiver and is higher in weak signal areas For extended battery life the modem should be switched off for most of the time Time
25. Isodaq Frog RX Logger User Guide August 2 2011 ISOD AQ Introduction to the Frog RX The Frog RX is a telemetry data logger It takes measurements from a single or a multi parameter sensor at regular intervals and stores this data in internal memory Using GPRS or GSM telemetry the Frog RX contacts a data collection system typically once per day and transfers data to the data collector The Frog RX can also be configured for alarms with user specified set points When a measurement exceeds a set point the Frog RX contacts the data collector and transfers data along with an alarm message The alarm message is typically forwarded by the data collector as an email or an SMS message The Frog RX manages power to both the modem and sensors A battery life of up to 7 years is possible Internally either a Lithium or an Alkaline battery pack can be fitted Power can also be taken from an external DC source The Frog RX is designed for ease of sensor connection 12V sensor power is generated from the internal battery pack A single sealed 4 way connector with screw terminals allows easy connection of sensor wires The Frog RX has an internal bag ventilation system which prevents liquid from reaching the battery and electronics and provides barometric compensation for gauge pressure level sensors It is IP68 and will withstand 2m immersion for 48 hours without significant ingress The shape of the Frog RX and the mounting system su
