1.3. GLOSSARY
1.3.1. Auto-IP:
This is when the power supply configures it’s own settings because they
cannot be obtained using DHCP. When forced into an auto-IP situation, the power
supply will select a random address in the range of 169.254.xxx.xxx
1.3.2. Auto-MDIX:
An electrical connection that automatically detects either a patch (straight-
through) or a cross-over LAN cable. Either type of LAN cable is acceptable
1.3.3. Auto-Negotiate:
The power supply will automatically choose the fastest speed that
the network can support. The Genesys™ power supply can operate at 10 megabits per
second (Mbps) or 100 Mbps
1.3.4. Command:
A message sent to the power supply which changes one or more of it’s
settings. It may be sent using a SCPI command or from the web pages. No response
message is returned, but an error message may be created
1.3.5. DHCP:
The Dynamic Host Configuration Protocol is a method where the IP address
and other settings are loaded from the network server to the power supply. This means
the IP address and other settings may automatically change each time the network
connection is created
1.3.6. Hostname:
A unique name for a device on a network. A descriptive name may be
created by the operator. For the default hostname, see section 3.6
1.3.7. IEEE 802.3, 10BASE-T, 100BASE –T:
These specifications define the physical
characteristics of a network including the cables and transmission speeds. Most often
have 8-conductor twisted-pair CAT-5 cables with RJ-45 connectors
1.3.8. Ethernet:
The most common configuration for a LAN. It includes connection detection
and message collision protection
1.3.9. IP
Address:
The “Internet Protocol” address is a numeric identifier that says where
messages are sent to or received from. The IP address may be fixed or it may be
assigned a different value every time the power supply is turned on. It has four
numbers, each zero to 255. Example:
10.190.34.17
1.3.10. LAN:
A “Local Area Network” is usually a small group of computers, printers and other
devices connected to share information and services. With a gateway, these devices
can also connect to a Wide Area Network (WAN)
1.3.11. LXI: “
LAN Extensions for Instrumentation”. A standard adopted by many test and
measurement companies. To be LXI certified, an instrument must conform to many
requirements including network connectivity, web page operation and software drivers.
See http://www.lxistandard.org/home for details
1.3.12. MAC Address:
The “Media Access Control” address is a identifier for the manufacturer
and the instrument. It is like a serial number and it may be used to configure the LAN
connection. It has six hexadecimal values.
Example:
00:19:f9:00:3e:26
1.3.13. Query:
A message sent to the power supply which reads back a setting or a
measurement. A query does not change any settings. It may be sent using a SCPI
command or from the web pages
