Hey everyone! I am not sure if this is the right place to post this, but I feel like it relates to networking. I work at a chemical company and we have a peace of lab equipment; a Varian CP-3800 GC - it is a Gas Chromatograph that connects to an old computer we have sitting running Windows XP SP3 and has a NIC card in it with a BNC connector. This peace of lab equipment runs over this BNC connection. So what I am trying to do is to migrate to a new computer; put the NIC card in the new computer running Windows 7 x64. Here are my problems though.
The BNC card manufacture, Realtek has not made drivers for Windows 7. Model of the NIC is RTL8029AS.
I tried a BNC to RJ45 converter, but it seems like either the GC does not see the connection or the converter is bad, but the RJ45 lights blink but the BNC lights show no activity. Has anyone delt with something like this before?
Varian 3800 Service Manual
I found a users manual for the Varian CP-3800 GC here: It uses a 10Base2 Ethernet interface, as zx10guy mentioned is also called ThinNet. It looks like both ends of the cable need to be terminated, so have you tried that? I doubt you will find a 10Base2 PCI card that has Windows 7 drivers, so you might look into a media converter like this: Also note, I have had problems with compatibility between 10/100 equipment and gigabit Ethernet equipment, if using a gigabit Ethernet switch to connect them. Auto-negotiation of speed or duplex doesn't always work. Recommend using a 10/100 switch.
Varian 3900 Service Manual
Hey guys well I tried these things. Formated and Installed Windows 7 32 (previously x64). Driver installed on the 32 bit Windows 7 (Used Windows XP Driver). The BNC card has Ethernet and BNC connector, yet I can browse the web with the Ethernet plugged in and DHCP, but when I assign it a static IP it says (unidentified network) but on Windows XP (our old PC) it says Connected even though there is no cable connected to the card with the same static IP it uses with the GC. So we know the card is able to work on Win7 32 because the Internet works over it on DHCP. Also keep in mind this card if OFF the network, what I mean is it has a static IP which is only connected to the lab equipment. I am trying to figure out why under status on the old PC (running XP pro) says Connected; no cables plugged in; yet in Windows 7 it says Unidentified Network?
If I can get that to say Connected I will be able to launch the GC software. Any ideas guys? Let me know if you got questions. Once again I thank you all for all your time, effort and help.
