What is required?

License:

Timebase Class 1

Connection:

A free 10Base2 Ethernet port and the following items are required:

  • 3800 GC Communications Board (Varian part no. 392580401 + 3800 ROM Firmware: Varian part no. 392504901)

  • 10Base2 Ethernet Cable (NIC) (This cable is a coaxial Ethernet cable, not the common twisted-pair cable)

  • In addition, two BNC tee connectors are required. If no other devices are connected to the Ethernet, two BNC terminators are required.

Software
Prerequisites:

No BootP server is required.

Control Panel:

To control the instrument, use the Varian3800.pan from the
Dionex Templates\Panels\LC_Other folder in the Browser.

 

Hardware Installation

Device Connection:

PC Ethernet NIC: For maximum reliability, Dionex recommends connecting the Varian CP-3800 GC to the instrument LAN (not to the office LAN). You have to install an additional Ethernet network interface card in your PC. Use the TCP/IP protocol; do not use any other protocol, such as, IPX/SPX.

For more information about how to connect the Varian CP-3800 GC via TCP/IP, refer to  Connecting Devices via TCP/IP (LAN)

Device Settings:

For the TCP/IP control settings of the Varian CP-3800 GC, refer to  TCP/IP Control: Settings on the Varian CP-3800 GC.

Restrictions:

The Varian CP-3800 GC does not support locking the keyboard; manual input is still possible. Do not enter any commands via the keyboard if you control the GC via Chromeleon.

 

Software Installation
