By default the user name and password are both “admin”. Entering admin in both fields
will bring up the IP Address Configuration page from where the various LAN
parameters can be set.
The following table provides a list of the LAN parameters and their descriptions.
LAN Parameter Description
IP Address
Use the
SYST:COMM:LAN:ADDR
command from a terminal to
change the address
To set a fixed IP address (i.e. 192.168.1.100) enter
SYST:COMM:LAN:ADDR “192.168.1.100”
Note that the IP address is placed in quotes.
To set the unit for DHCP mode enter
SYST:COMM:LAN:ADDR “0.0.0.0”
Note that this setting will not be made until either the power is cycled
or the
SYST:COMM:LAN:APPL
command is entered.
MAC Address
This is the Media Access Control address. It is a 16 digit
hexadecimal value. This number is unique to each device and may
not be changed by the user. It is visible as a serial tag which is
placed on the rear of the unit.
The MAC address may be displayed with the query command,
SYST:COMM:LAN:MACA?
Note:
If the MAC Address displayed is corrupted or does not match the
serial tag, there may have been a problem retrieving the LAN port
settings. This can happen if a static IP was set that conflicts with
another device on the network. To recover, turn on power to the unit
while holding down the SET key. This will allow the unit to boot without
attempting to collect the IP settings. You can then set the required IP
values. [See IP Address above].
GWAddress
Gateway address setting. A
default gateway
is a node (a router) on
a computer network that serves as an access point to another
network.
Note: If the power supply is connected to a router that does not have
a gateway (i.e. the uplink port is not connected on the router) then a
random IP address will appear on the gateway when it is queried.
This value can be changed by using the command,
SYST:COMM:LAN:GWAD <address>
For example to set the gateway address to 192.168.1.1, use the
command
SYST:COMM:LAN:GWAD “192.168.1.1”
Any change to this value will NOT take effect until after power to the
unit has been cycled.
