Troubleshooting

Follow the procedure below to isolate and resolve SDL500 communication problems.

Direct Connect

Symptom Possible Cause Corrective Action
Cannot communicate with iChart Incorrect COM port or wrong port settings Check the COM port the data logger is connected to and verify the Detail field in the iSIC Setup window reads “COM#, 9600 baud, N81, None”.
Bad physical connection Make sure the USB interface cable is completely plugged and threaded into the top port on the SDL500.
Insufficient power Install internal D-cell batteries into SDL500 and try connecting again
Short in sensor cable Replace sensor cable

 

Cellular

Symptom Possible Cause Corrective Action
Cannot communicate with iChart Low battery voltage Check battery voltage and replace batteries as necessary. Voltage must not be less than 9.5 V for cellular modem to function.
Bad physical connection Make sure the antenna is completely plugged and threaded into the top port on the SDL500C.
Low cellular strength Move the SDL500C and antenna to a different location to maximize signal strength.
Short in sensor cable Replace sensor cable

 

Radio

Symptom Possible Cause Corrective Action
Cannot communicate with iChart Incorrect COM port or wrong port settings  Check the COM port the radio base station is connected to and verify the Detail field in the iSIC Setup dialog box reads “COM#, 9600 baud, N81, None”.
Low battery voltage  Check battery voltage and replace batteries as necessary in the data logger. Voltage must not be less than 7.5V for radio to function.
No power to base station  Confirm the green LED on the power adapter glowing green.
Bad physical connection (SDL500R)  Make sure the antenna is completely plugged and threaded into the top port on the SDL500R.
Bad physical connection (4100-BASE)  Make sure the connections from the base station to the antenna and to the PC are secure.
No line of sight or out of range Move the SDL500R antenna and/or base station antenna in an effort to achieve a line-of-sight between the two, making sure that they are no more than one mile apart.
Short in sensor cable Replace sensor cable
