1 Installing the GC
Configuring GC-MS communications (5877B)
After configuring the GC IP address, next configure the MS IP
address (if not already done).
Once the instruments have IP addresses and are connected to
the LAN, complete the GC/MS configuration and enable
enhanced communications, Parts Finder data, and MS-friendly
features such as the MS Vent method as follows:
1 Press [Config] [MSD/Aux Det].
2 Scroll to IP. Enter the numbers of the MSD IP address,
separated by dots, and press [Enter].
3 Scroll to GW. Enter the Gateway number and press [Enter].
4 Scroll to SM and press [Mode/Type]. Scroll to the appropriate
subnet mask from the list given and press [Enter].
5 Reboot the MSD.
6 Press the down arrow to scroll to Request MSD Reboot?.
7 Press [On/Yes] to reboot the MSD and wait for the MSD to
complete this cycle before trying to access it.
After establishing GC-MS communications and configuration,
next configure GC-HS communications, if applicable, or
continue to “Step 4. Connect gases and traps”.
Configuring GC-HS communications
The 7697 headspace sampler can be configured to communicate
with the connected GC. This feature requires a HS with
firmware A.01.06 (or greater). With communications
configured, the HS knows GC method timings and programs,
and can synchronize with the GC clock and follow the GC
instrument schedule.
To configure GC-HS communications:
1 At the headspace sampler keyboard, press [Options], then go
to Communications > GC.
2 Enter the GC's IP address, then press [Enter].
3 At the GC keyboard, press [Front Injector] if the headspace
sampler is connected to the GC front inlet, or press [Back
Injector] if it is connected to the GC back inlet.
4 Scroll to No Headspace, then press [Mode/Type]. A list of
headspace sampler models appears. Scroll to the correct one,
then press [Enter].
5 Press [Options], then select Communications.
