LAN adapter part number

There are some notifications/warnings that may pop up on the GC display. These are from the manuals:

For non-GPIB network connections as of early 1998, the 6890A would have used an HP JetDirect LAN card (like J2552B)

 The 6890N, LAN is built-in.

Remember that these are very slow connections compared to what we are used to now, but they were state-of-the art in 1998!

Warning 103—Signal 1 buffer full

Warning 104—Signal 2 buffer full

Status message: Signal 1 buffer full or Signal 2 buffer full

This error could occur if you are using a data collection device, such as an

integrator or ChemStation. If the data collection device goes off line during

a run, signal data will be stored in the 6890 GC signal buffer. The buffer holds

400 Kilobyte of data; if the amount of data exceeds the buffer’s storage limit,

this warning will appear. No new data is stored after the buffer is full.

❐ There is a problem with the PC, the cabling to the PC, or the local network

that links the GC to the PC. Check the PC, cabling, and network.

❐ The PC was turned off without closing the ChemStation instrument

session. The GC collects and stores real-time plot data until the buffer

overflows and the warning appears. Next time, close the instrument

session before turning off the PC so that the GC stops collecting data.

❐ The PC entered power saver mode. When the PC enters power saver mode,

its processor slows down and cannot collect data fast enough for normal

communications, eventually causing the warning to appear. If the PC

stays in power saver mode overnight, for example, there will be an error

on the GC but the ChemStation will show a Ready status. Close and

restart the instrument session, and disable the PC’s power saver feature.

❐ There was a software problem on the PC that stops data collection.

❐ There is a hardware problem in the GC. If the problem persists, contact

Agilent Technologies for service.

Warning 122—Host communication: data overrun

Status message: Comm data overrun

The 6890 GC received data from a computer or workstation faster than it

could process it. The data may be lost

❐ Lower the baud rate or turn on handshake mode. You can adjust both of

these parameters from the Communications control table, which is

accessed from the Options control table.

Warning 123—Host communication: data error

Status message: Comm data error

The 6890 GC received bad data from a PC or workstation. The data may be lost.

❐ The data bits or parity may be set incorrectly. You can adjust both of these

parameters from the Communications control table, which is accessed

from the Options control table.

Warning 124—Host communications: abnormal break

Status message: Comm abnormal break

There is an interruption in communication between the 6890 GC and a PC or

workstation. This could be caused by a LAN disturbance or a bad cable

connection. Data may be lost

❐ If you are connected to the LAN, check to see if it is down or there is a

problem with your connection to it.

❐ Check the cable connection between the GC and the computer or

workstation.
