Improving Automation Through Innovation

DataLynx FAQ

FAQ 1: Why does DataLynx keep reporting busy?

The modem might be busy handling other calls.  Confirm that the modem is not currently busy with other sessions.  Another reason may be due to the use of a computer modem. There are certain versions of software modems that will not work correctly with hardware modems.  If this is the case, it is recommended that you obtain a hardware modem.


FAQ 2: Why does DataLynx manage to dial but cannot read the data?

The configuration might have the incorrect station number.  Also, try increasing the number of retries.


FAQ 3: What type of modem do I need?

For AutomationDirect PLCs we recommend the MDM-TEL product.  At minimum, the modem must support auto-answer and must support the same baud rate as the device you are using.  Please refer to the manufacturer's documentation or user manual for more information.


FAQ 4: What kind of configuration do I need for the device?

At minimum, it must support Modbus slave with a 9600 bps connection.
