Connecting Devices to the Chromeleon Server PC
Connecting Devices via TCP/IP (LAN)

Chromeleon supports TCP/IP control via a LAN connection.

The following devices require a BootP server:

Some devices that use TCP/IP communication protocol cannot permanently store their IP address. Therefore, a BootP server is required to control these devices via a LAN connection. The BootP server communicates the correct IP address to each device on the LAN; this is necessary, for example, after a power failure.

Depending on the LAN card:

If a J2552B LAN card is used:

 Agilent 6890 GC

 Agilent 6850 GC

The following devices do not require a BootP server:

 Agilent 1200 HPLC System

 Agilent 7890 GC

 Shimadzu SPD-M20A PDA Detector

 Thermo Scientific Accela Autosampler and PDA Detector: LAN Connection

 Thermo Scientific Surveyor Plus PDA Detector

 Thermo Scientific Surveyor Plus Autosampler

 Thermo Scientific Surveyor Plus LC Pump

 Varian CP-3800 GC

 Tips:  

Dionex recommends connecting chromatography devices to a dedicated instrument LAN to avoid conflicts with data transport via the office LAN. For the instrument LAN, set the speed to the maximum speed of the JetDirect card.

When using a 10Base2 Ethernet cable, verify that 10Base2 is the selected media type in the network configuration. To check this, right-click to open the properties of the network environment.

Open the properties of the network connection from the context menu. Click Configure on the General tab page.

On the Advanced tab page, select Media Type. (Usually, Auto Select is selected when the network card is installed for the first time.) If problems occur when the system tries to recognize the network cable, select 10Base2 and exit all dialog windows by clicking OK. The following steps provide details necessary for installing an appropriate IP address structure. The steps also provide help on installing and configuring an additional network interface card and BootP server software.

Using TCP/IP to control instruments requires sound knowledge of IP address assignment strategies to prevent IP address conflicts, which may impair existing networks. Follow the required steps to avoid IP address issues during configuration.
