3. Configuring the Ethernet Connection

For users wanting to access information externally from the hardware, a communication connection

to the Gryphon – S3 must be established via an Ethernet link. This connection will allow you to send

and retrieve data, execute an onboard application, or run DG’s Hercules application, for example.

3.1 Connection to the PC

You must have access to an Ethernet connection. Your office, workshop, or factory floor may already

be equipped with such a link. If it is not, or if you are establishing a point-to-point connection with a

dedicated PC not already equipped with Ethernet, then an appropriate network card must be installed

on your PC.

A null 100-base-T (100T) cable is provided with the Gryphon package, for use in a point-to-point

configuration with a PC. This cable connects the Gryphon’s 100T Ethernet port (on the back of the

unit) to a host PC’s Ethernet port. (To connect the Gryphon to an Ethernet hub, you will need to use a

standard 100T cable instead of the supplied null cable.)

Note: Null Ethernet cables are sometimes referred to as “cross over” cables.

Figure 3: Ethernet Cross Over Cable

3.2 Default IP address

Ethernet communicates by having each individual device on a network using a unique Internet

Protocol (IP) Address. Along with these addresses, there are the Netmask, Broadcast and Default

Route Addresses to configure.

1 3

2 6

3 1

6 2

twisted pair #1

twisted pair #2

GRYPHON® - S3 MANUAL

The hardware has predefined default parameter values. If you are using the tool one-to-one with

your PC, these parameters typically do not need to be changed. You will need to change these

default parameters, however, if your PC is not configured as a DHCP Client, or if you want to

connect the hardware to a network.

The following table lists the Gryphon’s default addresses:

Parameter name Hardware default value

IP (Internet Protocol) Address 192.168. 1 . 1

Netmask 255.255.255.000

Broadcast 192.168. 255 .255

Default Route 192.168. 2 1

Table 1: TCP/IP Settings

Note: To enable communication with a Gryphon unit at this Í address, your PC’s IP

address must be configured to: 192.168.001.002.

Prior to establishing a Gryphon connection with your building's existing LAN, you should contact your

company’s network administrator and coordinate new values for your Gryphon.

3.3 Configuring the IP Address

There are two methods you may use to configure the hardware’s TCP/IP Ethernet parameters:

(1) access the Gryphon’s on-board Web server, and utilize the Gryphon’s Web page, which

includes a configuration tool used to set IP parameters and passwords. The page may

be accessed through any Web browser with network access to the Gryphon unit. Two

browser examples are outlined in this chapter.

Netscape, a GUI-based browser (see sections 3.3.1 and 4.1); and

Lynx, a text-based browser (see sections 3.3.1, 4.1 and 4.3.2)

GRYPHON® - S3 MANUAL

3.3.1 Using a Web browser to modify the Gryphon’s TCP/IP parameters

You may access the hardware configuration pages via a forms-capable browser (like Netscape, IE,

or Lynx) on a network-connected computer. Please note: this option requires that the current TCP/IP

parameters allow communication over the network. If communication over the network is not

possible (as is often the case when reconfiguration is required), then the TCP/IP parameters must be

changed either through the method described in section 3.3.1, or that described in section 3.3.2.

1. Verify that your PC’s TCP/IP settings do NOT match those set for the Gryphon® unit. (The

Gryphon’s default parameters are IP Address = 192.168. 1 . 1 , Netmask = 255.255.255. 0 .)

2. Start your Web browser. Type the following URL: http://192.168.1.1 The following Web

page, with its six areas for viewing (System Administration, Modules/Pinouts, Gryphon® Stats,

Channels/Stats, Documentation and Dearborn Group), appears as shown below.

3. Next, click on System Administration. Once you enter this section, a box will prompt you for a

user name and password. The default user name is sysadmin; the default password is

dgGryphon. (Note: this password is the same as the default root password.)

GRYPHON® - S3 MANUAL

Once logged in, the DG Gryphon® System Administration page will appear: On this page, you can

configure the connection parameters and change the time and date.

You may set the following parameters:

• Time/Date - Enter the new values, and click Submit Date Changes. A screen verifying

the change should appear.

• TCP/IP Configuration – Enter your configuration type and any Static Configuration

Parameters, if necessary.

• Configuration Type By default the hardware is configured as a DHCP server. See

Appendix C for more information about what selection you should choose. All selections

GRYPHON® - S3 MANUAL

are valid for Gryphon hardware, while S-CAT hardware owners should NEVER choose

DHCP client.

• To make your changes, provide new values where necessary, and click Submit TCP/IP

Changes. Then turn the Gryphon off and on, (i.e., reboot), to invoke the changes.

• Startup Programs / Services - A checkmark indicates that a program is currently active

on the Gryphon®.

• Change Sysadmin Password - Provide a new sysadmin password, and click Submit

Password Change. A screen verifying the change will appear. (Please note that only

the sysadmin password, not the root password, will change.)

4. On-board Utilities

With an on-board Linux operating system, Gryphon users have a host of utilities they can access.

4.1 Using a Web browser to modify the Gryphon’s TCP/IP

parameters

You may access the webpage utilities via a forms-capable browser (like Netscape, IE, or Lynx) on a

network-connected computer. Please note: this option requires that the current TCP/IP parameters

allow communication over the network. If communication over the network is not possible (as is often

the case when reconfiguration is required), then the TCP/IP parameters must be changed either

through the method described in section 3.3.1, or that described in section 3.3.2.

1. Verify that your PC’s TCP/IP settings do NOT match those set for the Gryphon® unit. (The

Gryphon’s default parameters are IP Address = 192.168. 1 . 1 , Netmask = 255.255.255. 0 .)

2. Start your Web browser. Type the following URL: http://192.168.1.1. The following Web
