2.1.1 Troubleshooting RS232 Sensors
Any NexSens iSIC data logger can “pass-through” telemetry and open a terminal directly to
RS232 sensors. Sensors such as YSI sondes, or other ASCII communication devices can be
directly accessed through this menu.
In iChart, select “Advanced | Terminal”, and select the PC COM Port the data logger is currently
connected to from the drop down menu. Next place a check in Use iSIC and select the iSIC
model number from the Connection drop down menu.
The iSIC Address will typically be 1 unless changed by the user.
The iSIC Port will be the port that the device is wired to. Select Port 0 if you are using the iSIC
MS8 connector, located on the front of the iSIC. Otherwise, select the Port number that reflects
the Rx and Tx pins the device is wired to (P1 was used in the wiring section of this manual).
Note: the iSIC will use the RS232 baud rate and frame it is programmed with. If an RS232
sensor has not been already configured on the data logger the iSIC will default the terminal to
9600 baud N81.
Click OK and the terminal window will appear:
