In order to update a SDL’s firmware using a UW-USB-485P communicaiton cable, the communication protocol must be changed to RS-485. 1. Establish temporary RS-485 communicaiton with the device by following the steps in the Direct connection with an SDL500 via RS-485 article. 2. From the menu bar select Edit | Preferences. 3. Switch to the GUI tab. 4. Check the “Enable […]
The address of an iSIC or SDL500 data logger can be changed using iChart software. 1. Open iChart with a current project if not already open 2. From the menu select Advanced | iSIC | iSIC 3. Select the correct PC COM port, Connection type and iSIC Address If the address is unknown and the connection […]

The setup incorporates an integrated spread spectrum radio modem for license-free remote data collection from up to a five mile line of sight from the radio base station. What’s Included Data logger with spread spectrum radio modem 20-Watt […]
Overview The NexSens 4100-iSIC (Intelligent Sensor Interface and Control) uses an integrated spread spectrum radio modem for license-free remote data collection from up to a five mile line of sight from the radio base station. What’s Included Data logger with spread spectrum radio modem 12 VDC battery iSIC Kit (2) Gland fittings (5) Desiccant packs […]
This guide is designed to help you fix common problems associated with failed over-the-air communication between a radio iSIC or SDL data logger and a computer. Radio communication problems can arise for a number of different reasons, including low or no power, weak or out of range radio signal, and improper physical connections. To troubleshoot […]
The battery that powers an iSIC data logger is user-replaceable. 1. Disconnect the fastons from the battery terminals inside the iSIC. 2. Remove the two screws on the battery plate with a #3 Phillips head screwdriver. Store the battery plate and screws. 3. Remove the old battery and put the new battery in its […]
Analog sensors require a millivolt (mV) reading in order to determine an accurate output. To find these readings, follow the process below. 1. Open iChart without a project file. 2. Select Advanced|iSIC|iSIC from the menu bar. 3. Select the appropriate communication under PC Settings. 4. Type the address of the data logger and click Connect. 5. Click the Analog tab. […]
In order to connect a sensor to the iSIC, the output voltage must be cut down to 2.5V. In order to accomplish this, two resistors must be utilized to act as a voltage divider. The diagram below demonstrates the proper connection for a 5V sensor. Note: ADx is any single ended iSIC analog inputs […]
The iSIC plate is designed to hide all the parts that are not meant to be altered by the customer. However, there are a few occasions when it is necessary to remove the plate. For example, parts could fall behind the plate, or the PCB may need to be sent back to NexSens for repair. […]
Switch power is used in data logging applications where power must be conserved. There are two separate implementations of this concept within the iSIC data logger. Sensor Switch Power Sensors plugged into SDL ports P1, T, and A or powered through pin 2 of an iSIC’s digital terminal strip are powered using switch power. This […]
