The NexSens 5100-iSIC (Intelligent Sensor Interface and Control) uses an integrated Ethernet modem to provide a dedicated port for continuous Ethernet-to-router communication.

What’s Included

  • Data logger with Ethernet modem
  • 12 VDC battery
  • iSIC Kit
  • (2) Gland fittings
  • (5) Desiccant packs
  • RS-232 interface cable
  • (4) 56 Ω resistors
  • CAT5E Patch cable
  • DB-9 Null modem adapter
  • Grid connect driver and utility software CD

Software Installation

1. Install iChart software on a Windows computer using the provided CD-ROM or from the NexSens Downloads page:


2. If iChart is installed on a PC with Windows Vista, 7 or 8 OS, setup the software to run with Administrator privileges to allow write access to the Program Files directory:


3. Register the software online when running for the first time:


4. On the iChart PC, insert the Grid Connect software CD and click Go to Software Page.

Ethernet Modem Configuration

The CPR Manager is used to assign a virtual COM port to the Ethernet modem, which can be accessed by iChart in order to communicate with the 5100-iSIC data logger. While the Ethernet modem may be assigned an IP address via DHCP, a fixed (static) IP address must be provided so that the COM port settings do not change. Setting a static IP address is done by connecting directly to the Ethernet modem using the instructions provided at this link:


COM Port Configuration

6. Within the iSIC enclosure, connect the DB-9 cable to the connector on the iSIC board.

7. Using the CAT5E Patch Cable, connect the iSIC to the same local network the computer is on.

8. Power the iSIC by connecting the 12 volt battery and/or external power supply. 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.

The device Host and TCP Port information will appear in the Settings tab. Note that the port forwarding requires that the TCP Ports 10001 and 9999 must not be blocked by a firewall. Additionally, the UDP ports 30718, 43282 and 43283 must be added to the firewall exclusion list if the device will be accessed from outside the LAN (see Warning! note in screen shot below).

15. Select the correct COM port (from CRP Manager setup), then select 5100-iSIC from the connection drop-down menu. Enter the 5100-iSIC address if known, or leave at 0 if unknown. Click Connect.

16. When the button changes to Disconnect, click the General tab. Confirm the connection is successful by verifying that valid information displays in the Status group box at the bottom of the window (iSIC time, battery voltage, etc). If ??? is displayed, return to the CPR Manager and/or Connection tab and check the communication settings.

Configuring with iChart

18. Refer to the Sensor Interface Guides for connection of sensors.

19. Ensure power is supplied to the data logger.

20. Add the 5100-iSIC to an iChart project file.

  • Follow the Setup Device Wizard to add a site name, and then select 5100-iSIC from the list of NexSens data loggers. Enter the correct PC COM Port at the prompt and click Test Connection to check communication. Add sensors in iChart by selecting the manufacturer and model number. Continue the Setup Device Wizard, make sure the 5100-iSIC is selected and click Program iSIC to conclude configuration.
