This error occurs when a TCP connection cannot be established when connecting to a network device using TCP/IP.

<Cause>

1. The LAN cable is not connected correctly.
   Or power to the connected device is not turned on.
   
   
2. "Disconnect" is displayed at the bottom left of the Main Menu → Ethernet screen.
   
   
   
3. Communication settings (IP address, port number, etc.) on the TSi/V series
   do not match those of the connected device.

<Solutions>

Case A

• Check if the LAN cable is connected to the LAN connector correctly.
• Turn power to the connected device off and on again.
  
  

Case B

"Disconnect" displayed at the bottom left of the Main Menu → Ethernet screen must be changed to "Connect".

• Depending on whether the hub is used or not, the cable type to use varies.
  Check the cable in use.
  - With hub: Straight cable
  - Without hub: Cross cable
  
  
• When a hub is used, check the LED that indicates the hub link condition.
  If not lit, check the cable, and insert it into another empty port on the hub.
  
  
• Turn on the hub again.
  
  
• Check for errors in setting, such as exchanged data between the subnet mask and default gateway of the TSi/V series.
  
  

Case C

• Check that the [Maker], [Model], and [Target Port No.] settings of the connected device are configured correctly in the screen program.
• Check that the IP address, port number, and other communication settings match on both the connected device and the TSi/V series unit.
