   • Check for errors in setting, such as exchanged data between the subnet mask and default gateway of the V series.
3. Check the IP address of the V series on the [System Information] menu in Local mode, and set it on the [Transfer] -> [Communication Setting] dialog.
   
4. Check a ping from the PC to the V series . Or, check a ping from the V series to the PC (click here for how to check).

2. The COM port number set on the [Transfer] -> [Communication Setting] dialog is not consistent with the COM port number of the PC.

<Solutions>

1. Check if the transfer cable "V-CP" is connected correctly to the MJ1 port of the V series.
