Direct LAN connection between PC and chromatograph

This procedure describes how to connect a PC directly to a chromatograph using an Ethernet cable without a network switch.

1. Connect the PC and the chromatograph using a cross-over Ethernet cable. A straight-through cable is not recommended.
2. Open Windows settings:
   • Settings → Network & internet → Advanced network settings.
3. In the Network adapters section, locate the Ethernet adapter and expand it.
4. Click Edit next to More adapter options.
5. In the Ethernet Properties window, select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
6. In the Internet Protocol Version 4 (TCP/IPv4) Properties window, select Use the following IP address.
7. Enter the IP address:
   • The first three numbers define the network and must be the same as in the device IP address.
   • The last number defines the device and must be unique within the network. Do not use an address already assigned to a connected instrument.
8. Ensure that other Ethernet boards in the computer do not use the same network.
9. Set the Subnet mask to 255.255.255.0.

If communication with a LAN-connected device is lost after restarting the PC, refer to Device connected via LAN does not communicate after PC restart.
