Connect Errors

Connect Errors - the most common connection errors occur due to faulty or intemittent connections.  If you receive a "Error connecting to TCF" error, check the following possible problem sources.

• Check the COM port assignment of your USB-to-Serial converter as described under Determining COM Port. 
  
  
• Check that the PC Serial Port connector, if not purchased from Optec, is wired correctly. 
  
  
• Check the flat Reverse cable.  You easily check that each end of the RJ12 connectors are wired straight through.  That is, Pin 1 on one connector should be connected to Pin 1 on the opposite connector.  When looking at the Reverse cable connector ends, the wire colors should appear identical as shown below.
  
  

• Check that the RJ12 connectors are properly inserted into the TCF-S focuser control box and the PC Serial Port Converter.
