LAN Parameter
Description
Host Bits
Number of host bits as opposed to network bits in network mask. A
CIDR class C network uses 24 network bits and 8 host bits. (Class A
= 24, Class B = 16). This value can be changed with the command,
SYST:COMM:LAN:CLASS <number>
As an example, to set to Class A, the command would be
SYST:COMM:LAN:CLASS 24
Note that many systems refer to an alternate description referred to
as the subnet mask. Some conversions from subnet mask to class
are:
Subnet Mask Class
255.255.255.0 24
255.255.0.016
255.0.0.0 8
Any change to this value will NOT take effect until after power on the
unit has been cycled.
Port No
TCP remote port number. This value must be set to
5025
(SCPI) to
support the built in Web page.
This value can be changed with the port number command:
SYST:COMM:LAN:PORT <number>
For example to set the TCP port to 5025, the command would be
SYST:COMM:LAN:PORT 5025
Any change to this value will NOT take effect until after power on the
unit has been cycled.
LAN Default
Factory default settings for LAN are entered by setting the right knob
to the PGM location, and then selecting LAN with the left knob and
pressing and holding it until the “LAn R5t” message appears on the
front panel. The IP address is set to DHCP or AUTO IP.
Alternatively, the LAN may be reset with the SCPI command,
SYST:COMM:LAN:DEF
