Appendix A – TCP/IP Settings: DHCP or Static?
WARNING:
The S-CAT tool is intended for use ONLY in a point-to-point configuration with your
PC. The following instructions are included for information purposes only and should not be
implemented without the guidance of a qualified network administrator. Dearborn Group
assumes no responsibility for malfunction or damages resulting from use of the following
functions.
One of the hardest things to set up with the hardware is the TCP/IP addressing. To make this more
manageable, it is important to understand your PC’s configuration and the Gryphon’s configuration.
A.1 Definitions
DCHP SERVER:
Every TCP/IP device on a given Ethernet network needs a unique IP address assigned to it to
participate on that network. DHCP (Dynamic Host Configuration Protocol) is a protocol that allows a
designated server to assign unique IP address to clients that request them. Gryphon
®
can operate in
three different DHCP modes: DHCP Server Mode, DHCP Client Mode or DHCP Off – Static IP
Mode.
DHCP Server Mode
This is the default shipping configuration mode for the hardware. This means that a PC attached
point-to-point with the hardware can automatically obtain correct TCP/IP settings for use with the
hardware. In this configuration, the hardware uses static TCIP/IP settings for itself, but will act as a
DHCP server for other nodes on the network. Use this setting eliminates the need to configure
TCP/IP settings on the client PC. (Many company network administrators do not allow PC re-
configuration by their users.) This mode can be used to connect Gryphon
®
point-to-point to a PC
directly if the PC is configured to acquire its TCP/IP settings automatically.
Recommendation:
When using this mode, apply power to the Gryphon
®
hardware first so that it
is ready to serve the IP Address. When the PC is powered after the Gryphon, it will obtain an IP
address immediately on power up.
Caution:
Use this method
only
with a point-to-point connection. If the Gryphon
®
in server mode
is connected to a building network, it could cause network malfunctions!
