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 […]

Changing the Address of an iSIC or SDL500 Data Logger
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 […]
SDL500 Getting Started
Powering the SDL500 The SDL500 can be powered internally with (8) D-Cell batteries or externally with NexSens SP5 5-watt solar power packs or a user-supplied 12 VDC source. For MB-100 data buoy applications, internal batteries must be used to power the SDL500. For MB-300 or larger data buoy applications, SP5 solar power packs are typically […]

Powering an SDL Through Its Top Bulkhead
When many sensors are used in a project, it may become necessary to power a submersible data logger through its top bulkhead. This action will require a UW-plug-to-flying-lead cable. 1. Connect the UW plug to the top bulkhead. 2. The power will run through pin 6 of the bulkhead, which corresponds to the […]
Remove SDL500 Housing
If advanced diagnostics or repairs are to be performed on an SDL500 submersible data logger, the outer housing must be removed. 1. Remove the (4) 3/16″ hex screws from the main SDL500 body on the end with 5 ports (bottom bulkhead). 2. Pull the bottom bulkhead off of the main body carefully. Note: Since the SDL500 is air-tight […]
Millivolt (mV) Readings on an Analog Sensor
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. […]
Power Management – Switch Power
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 […]
