How to connect Agilent 6890N to Empower 3 FR5 via LAN and DHCP on DAC?
edited October 12
The GC is not communicating with the DAC after config by DHCP.
Instruments should always use fixed IP addresses. DACs and acquisition PCs usually expect instruments to have IP addresses within a certain range that seldom overlaps any DHCP address range.
Since you are using E3 FR5 ~
we are not using ChemStation right? They like the old BootP and static IP. Empower instruments should normally be DHCP. You can't run both!
I'm guessing the 6890N (LAN ready, not on GPIB..) is connecting to a Lace instrument ethernet nic? An eSATIN uses the GC digital signal out to DAC into ethernet Lace, that is not what your are asking about is it?
There should be two networks NIC's on this PC?
Is it connecting to another Agilent instrument? Is that the DAC?
List all the instruments connected and how. Pictures may help.
Help us with the details and the rest is TLDR for most.
Normally I remove any Waters instruments and only run Agilent on a lace. Waters recommends '3rd party' instruments be isolated. It can often be done fine; see the release notes. If you can't do that it may need deeper troubleshooting.
Power off everything, boot Empower Lace and wait 5 mins.
turn on the gas chromatograph and check the lights for happy green flashing comms. It may be that it still has a set (static) IP. The keypad should be able to set a new IP; gateway (GW) and subnet mask (SN)
---- LAN ----
IP: 000.000.000.000 <
Enable DHCP OFF
Power cycle when done and double check all three need to be valid for your Empower isolated instrument LAN. I normally pick a high number that will not conflict like 192.168.0.
/24 GW:192.168.0.1. YMMV do an
from a command prompt to double check current. We want to know the 2nd NIC. Then provide the command output and will try to help. A BIOS/Firmware update may be needed too.
