Each SDL500 submersible data logger includes the following accessories and spares to get started and keep the unit operational: SDL500 USB interface cable (Only included with direct connect SDL500, not with telemetry-enabled models) USB driver CD* (8) D-Cell alkaline batteries Maintenance kit SDL Guard removal tool (3/16” handled Allen wrench) (2) Spare SDL port plugs […]
The SDL500 Submersible Data Logger is configured with five sensor ports for connection to industry-standard digital and analog interfaces, including RS-232, RS-485, SDI-12, 1-wire temp string, 0-2.5 V, pulse count, and more. Each sensor port offers a UW (underwater) type receptacle with double oring seal for a reliable waterproof connection. Unlike many data loggers, the […]
Direct connection with RS-485 can be established by using a UW-USB-485P cable to communicate with the SDL500C, SDL500R and SDL500I. To do this: 1. Plug the USB cable into a computer. If it is the first time the USB cable is plugged into the computer, drivers (software) will be needed – an internet connection is […]
The maintenance switch is a feature in iChart software that can be used for external control of an iSIC data logger. Once the feature has been enabled and a channel has been set, a simple switch controls if the iSIC logs data or not. 1. Open iChart without a current project. 2. From the menu […]
NexSens iSIC data loggers have a default address of 1. When connecting multiple iSICs to a single PC COM Port, unique addresses must be assigned to differentiate between them. This problem occurs most often when using a system of 4100-iSICs. 1. Open iChart without a current project. 2. From the menu bar select Advanced |iSIC | […]
The iSIC data logger’s DIO0 and DIO1 lines are programmable digital input/output signals. In revision 6, the signals are 5V logic and can tolerate up to 6V. In revision 7, the signals are 3.3V logic and can tolerate up to 35V indefinitely. The most common use of these lines is to use them to drive […]
Many iSIC data logger commands can be executed remotely. However, this requires editing the .INI file, which can have hazardous effects if done incorrectly. Remote commands should only be used for very specific and deliberate purposes. 1. Open iChart without a current project. 2. From the menu bar select Edit | Preferences. 3. Switch to the GUI tab. […]
NexSens iSIC data loggers can connect to iChart software directly, or through the following telemetry options: analog phone modem, cellular modem, spread spectrum radio, Ethernet, or Wi-Fi. When setting up a new system or testing new configurations it is essential to establish and confirm communication between the iSIC and the PC. 1. Open iChart without […]
iSIC and SDL500 data loggers have optional Power Management settings that can be used to conserve power for systems with a high power demand or when solar charging and battery power are limited. The Power Management settings are implemented through iChart software. Power Management allows users to turn off power-hungry devices such as cellular modems […]
Every hour the iSIC will run self diagnostic. If during this process an error is identified the iSIC will remain in the boot loader. This can happen if the iSIC has not been used for 10 or more years, experienced a high surge (possibly due to nearby lightning or an Electrostatic Discharge), or had insufficient […]
