Cannot Connect

"Cannot Connect"

Connection problems can be caused by several factors. Go through the check list below if you have having troubles.

Make sure the serial cable is securely attached to your focuser or focuser hand control box. Also check that the cable itself is not damaged.
Make sure that your focuser has power. If you have a model that has a hand control box you should see the red digital display and LED light up when the power switch is set to ON. If you are using one the the TCF-Si focusers (without a hand-control box) you should see the red power indicator LED illuminated when the power cable is connected.
Verify that you selected the correct serial COM port in the driver setup dialog.
Verify that the temperature probe is securely attached to the focuser/hand-control box. If it is not the setup dialog will not be able to connect the device.
