Setting up a LAN Instrument Network 4
Identifying the Required Instrument LAN An instrument LAN consists of one or more data system computers and instruments. This manual covers instrument LANs for the following instruments: • Agilent 7890A, 7820A, 6850, 6890A, 6890 Plus, and/or 6890N Gas Chromatographs • Agilent 35900E analog to digital converter Identify the instrument LAN required: • Isolated (not connected to the site LAN).
Figure 2: Network multiple instruments on a LAN Site LAN You can attach the workstation and all of the laboratory instruments directly to a site LAN. The LAN site administrator assigns fixed IP addresses for each instrument you are adding to the network. Depending on your site LAN administrator’s direction, PCs added for instrument control can obtain LAN addresses automatically from the site’s DHCP server, or have fixed IP addresses. All PCs and instruments they control must be on the same subnet.
Windows Vista: Select Start > Control Panel > Network and Sharing > Manage Network Connections. Windows 7: Select Start > Control Panel > Network and Sharing Center. Then select Local Area Connection > Properties. From the Local Area Connection Properties screen highlight Internet Protocol version 4 and select Properties. Figure 3: Set the IP Address on PC 3.
Instruments on the LAN Each LAN instrument requires a unique IP address on the same subnet as the ChemStation PC to work correctly on the network. There are two types of instruments that can be added to either the local or site LAN. The first type of instrument allows the IP address to be entered directly at the GC. The second type of instrument requires the IP address to be assigned using either Agilent BootP or Telnet.
Instrument Firmware Requirements Table 1: Instrument Requirements Instrument Type Model Supported instrument firmware revision Method for setting IP addresses 7890A G3440A A.01.10.3 Set at GC keypad 7820A G4350A 7820A.01.10.013.1.bin (E,C,J) 7820A.01.10.013.Ru.bin Set using software keypad 6890N GC G1530N/ G1540N N.06.07 for 7693A And N.05.06 LAN Assembly Firmware 04.7B3 Set at GC keypad 6890 Plus, 6890A G1530A/ G1540A A.03.08 Chip Set Determined by Jet Direct card used – see below.
Setting IP addresses from instrument keypad When entering an IP address at an instrument, be sure it is correct and is not in use by another device (such as a printer). Setting the IP address for a 7890A GC 1. Pr ess [Options]. Scr oll to Communications and pr ess [Enter]. Scroll to Enable DHCP and, if necessary, press [Off/No] to disable DHCP. When prompted, turn the GC off and then on again. 2. Press [Options]. Scroll to Communications and press [Enter]. 3. Scroll to IP.
4. Scroll to SM and press [Mode/Type]. Scroll to the appropriate subnet mask from the list of modes and press [Enter]. The GC displays a message instructing you to power cycle the instrument. 5. Power cycle the instrument to apply the LAN setpoints to the card. 6. Press [Options]. Scroll to Communications and press [Enter]. Confirm that the correct setpoints are present.
The initial installation r equir es that you connect the software keypad dir ectly to the GC using this address. During installation this IP address can change or be set to use DHCP. 1. Start the software keyboard. From the Windows® Start program menu, Agilent > All Programs > Agilent Technologies > 7820A GC Remote Controller. 2. Connect to the GC. Go to Connection > Connect…. In the Target field, enter the current GC IP address 3. Click [Options]. Scroll to Communications and click [Enter]. 4.
Assigning IP addresses to instruments with Jet Direct cards IP addresses for the 6890A, 6890 Plus, 35900E, and 6850A with a Jet Direct card can be configured by using the following methods: • Manually setting the parameters using Telnet. • Automatically requesting the parameters from a BootP Server (using the Agilent BootP Service).
6. Add the instrument a. Follow Start > Programs > Agilent BootP Service > Edit BootP Settings b. Uncheck Do you want to log BootP requests? c. Select Launch Manager. The BootP Manager screen appears. d. Select Add… The Add Bootp Entry screen appears. e. Enter MAC address, host name, IP address, Comment (if desired), subnet mask, and gateway address. f. Select OK. 7. Add the instrument to the system. Repeat from step 5 for any additional instruments. 8. When finished, click Exit Manager, the select OK. 9.
Initialization Mode Selection The following initialization modes are selectable: NOTE Compared to the G1369A LAN card, SW 7 and SW 8 must always be in OFF position on the G1369B LAN card, otherwise the selected modes are not working. Bootp When the initialization mode “Bootp” is selected, the card tries to download the parameters from a Bootp Server. The parameters obtained become the active parameters immediately. They are not stored to the non-volatile memory of the card.
Since the default IP address is a local address, it will not be routed by any network device. Thus, the PC and the card must reside in the same subnet. The user may open a Telnet session using the default IP address and change the parameters stored in the non-volatile memory of the card. He may then close the session, select the initialization mode “Using Stored”, power-on again and establish the TCP/IP connection using the new parameters.
Figure 6: Telnet command where is a nonroutable unique local address that you assign or a routable address assigned by the site LAN manager. When the connection was established successfully, the card responds with the following: Figure 7: Telnet result 3. To set the IP address, subnet mask, and gateway enter the command for each instrument. The value of the command is shown in the table below. For example: ip 134.40.24.230 Press [Enter] after each command.
Information about the card Product id, firmware revision s, MAC address Initialization mode is Bootp. The connected PC/Bootserver is 134.40.30.184 Active TCP/IP settings Stored TCP/IP settings in non-volatile memory (not visible if equal to active TCP/IP settings) Connected to PC with controller software (e.g. Agilent ChemStation), here not connected Figure 8: Telnet information 5. Change the IP address (in this example 134.40.24.230) and type “/” to list current settings. Enter ip 130.40.24.
Verify communications using the ping command The ping command verifies communications across a TCP/IP connection. Ping does not verify if the subnet mask and gateway are correct. To use it, open the MS-DOS command prompt. Type ping followed by an IP address. For example, if the IP address is 192.168.1.56, enter ping 192.168.1.56. If LAN communications are working properly, you will see a successful reply.
Install the Jet Direct Card Accessories (if required) JetDirect Card accessory for the 6890A and 6890 Plus The JetDirect card for connecting the 6890A and 6890 Plus to the Chemstation via LAN can be added to an existing 6890 as accessory #G2335A which includes the G1369A Jet Direct Card. Part of the 6890 LAN option/accessory is a card cage and connector that accommodates installation of the JetDirect card. This card cage is not standard on every 6890.
JetDirect Card connection of the 6850 and 35900E to the Chemstation The Jet Direct Accessory Kit for the 6850 and 35900E (G1369A) consists of: • G1369-60001 – JetDirect Card • G1369-90000 - Manual • G1530-61485 – LAN Cable Category 5 100 Base-T twisted pair LAN cable (8 Meter) • 5023-0203 – Cross-over (PC to instrument) network cable (shielded, 3 m long) • 5023-0202 – Twisted pair network cable (shielded, 7 m long) Install the JetDirect Card in the MIO slot in the back of the instrument.
Chemstation LAN Installation Checklist Determine configuration – Isolated or Site LAN. Determine Instrument and PC IP addresses, Network Subnet Mask and Gateway. For each instrument and each PC with a fixed IP address record the IP address, subnet Mask, and default gateway. Install the Network Interface Card (if necessary). Install TCP/IP on the PC. Configure TCP/IP with IP Address/Subnet Mask/Gateway. Gateway is required only for Site LAN installation.
