Updating iSIC, CB-iSIC, or SDL500 Firmware

    NexSens iSIC firmware dictates how all functions and procedures are run in iSIC, CB-iSIC, and SDL500 data loggers. New firmware versions are released on a regular basis, so it is important to routinely check for updates. iChart software must be periodically updated in order for the most recent firmware version to be located.

    Directly Connecting to a 4100-iSIC Data Logger

    A 4100-iSIC is, by default, set up to communicate over spread spectrum radio instead of directly to a PC using its DB9.   To configure a 4100-iSIC to communicate directly to a PC instead of over radio: 1. First open iChart software and select Help | Check For Updates to get the latest version of […]

    Troubleshooting Radio Connection

    If at some point a 4100-iSIC no longer responds to iChart software, there are a few steps to follow to troubleshoot the connection: 1. First, make sure the COM port selected in iChart is correct. 2. Next make sure the base station is powered and operational. For a 4100-base, make sure the RS232 cable is […]

    iSIC Addressing

    Connect one end of the RS232 Interface Cable (supplied) to the PC’s serial port. Plug the other end of the cable into the DB9 connector located inside the iSIC. Apply power to the iSIC. If AC power will be used to power the system, connect the red and black battery leads inside the iSIC or […]

    4100-iSIC Addressing

    Multiple 4100-iSICs can be used in a system that incorporates a single 4100-Base Station or other iSIC telemetry. Doing so is as simple as assigning each device with a unique address. Every 4100-iSIC must have an address that is different from all the other radios in the monitoring network. iChart software will then use these […]

    4100-iSIC Communication

    NexSens offers four solutions for communicating to 4100-iSIC systems: 4100-base, 4200 radio to phone telemetry, 3200 radio to cellular telemetry and 5200 radio to Ethernet telemetry. The 4100-base system works like the image below. The 4100-base radio is connected directly to a computer via a RS-232 cable. This radio then communicates to all the 4100-iSIC […]

    4100-iSIC Typical Site

    The NexSens 4100-iSIC Spread Spectrum Radio system provides a convenient means of communicating and collecting real-time data from remotely deployed monitoring instruments. The NexSens 4100 radio uses 900MHz spread spectrum radio technology and allows hundreds of remote sites, each one with a unique programmed address, to be implemented in a single system. Below is an […]

    Digital Expansion

    The digital expansion connector allows for the addition of multiple RS232, and generic digital I/O sensors, as well as a main communication port. See the diagrams below for exact signal pins: RS232 The digital expansion connector allows for two additional RS232 sensors. These ports operate the same as those located on the digital terminal strip. […]
