The NexSens 6100-iSIC (Intelligent Sensor Interface and Control) data logger uses an integrated Iridium satellite modem for data transmission. This type of communication is used when other telemetry options are not feasible.

What’s Included

  • Data logger with Iridium satellite modem
  • 12 VDC battery
  • iSIC Kit
  • (2) Gland fittings
  • (5) Desiccant packs
  • RS-232 interface cable
  • (4) 56 Ω resistors

Configuring with iChart

1. Install iChart software on a Windows computer.
2. Connect sensors to the data logger. See the appropriate sensor interface manuals for wiring and other details. Bring any cables into the enclosure by removing a port plug and installing a gland fitting from the iSIC Kit.
3. Directly connect the 6100-iSIC to the computer via the RS-232 interface cable.
4. Power the iSIC by connecting the 12 volt battery. Observe the green blinking LED in the hole at the end of the analog terminal strip. This only blinks for 15-20 seconds during warm-up to confirm that the data logger is powered and ready.
5. Add the 6100-iSIC to an iChart project file.

To accomplish this: Follow the setup device wizard to add a site name and then select 6100-iSIC from the list of NexSens data loggers. Change the Connect through option to Direct to PC and then select the correct COM Port.

6. Add sensors in iChart by selecting the manufacturer and model number.
7. Continue the Setup Device Wizard and click Program iSIC to conclude configuration.
8. Right-click on the 6100-iSIC in the Site tree located in the navigation window of iChart. Change the Connect Through option to Internet and enter the IMEI number located on the inside of the door of the 6100-iSIC.

Field Installation

1. Mount the data logger to a wall, pole, or other secure location above flood stage using the A55 Mounting Plate.
2. Connect the A38 grounding kit wire to the copper lug on the bottom of the 3100-iSIC data logger and the other end to an appropriate earth ground.
3. Mount the A42 Iridium satellite antenna in a location that will maximize signal strength. Attach an RF cable from the antenna to the RF port on the 6100-iSIC.

Note: The satellite signal can be blocked if obstructed by metallic surfaces.

4. Connect the DB-9 cable inside of the enclosure to the DB-9 port between the green iSIC terminal strips.
5. Verify that all sensors are connected properly and power is supplied to the data logger.

Reconfiguring the data logger

To change settings like log and sample interval follow the procedure below:

6. Directly connect the 6100-iSIC to the computer via the RS-232 interface cable.
7. Open the project file in iChart. Right click on the 6100-iSIC in the Navigation Panel.
8. Change the Connect Through option to Direct to PC and then choose the correct COM port. Settings can now be modified.
9. When finished, reconnect the modem with the DB-9 cable and change the Connect Through option back to Internet.
