Sets the network port’s IP Address setting (see Section 8.2, Configuring the Network (LAN) Port, on page
65).
Parameter <IP address> is a string specifying the address using IP dot notation.
This setting is only allowed when DHCP is OFF.
The query form returns the static IP address when DHCP is OFF and returns the dynamically assigned IP ad-
dress when DHCP is ON.
8.7.3.105 SYST:COMM:SOCK:CONT OFF|ON|QUER
Query form: SYST:COMM:SOCK:CONT?
Sets the network port’s Control Enable setting. This determines whether the instrument accepts control com-
mands received via the network port.
Allowed parameter values are OFF, ON, and QUER. When the setting is OFF the network port cannot be used
to control the instrument, and all commands are ignored. When the setting is ON commands may be used to
control and operate the instrument. When the setting is QUER, commands that read settings and data are al-
lowed, but commands that change settings are ignored. The default setting is QUER.
8.7.3.106 SYST:COMM:SOCK:DHCP <boolean>
Query form: SYST:COMM:SOCK:DHCP?
Sets the network port’s DHCP Enable setting (see Section 8.2, Configuring the Network (LAN) Port, on page
65).
8.7.3.107 SYST:COMM:SOCK:GAT <IP address>
Example command: SYST:COMM:SOCK:GAT “147.120.0.1”
Query form: SYST:COMM:SOCK:GAT?
Sets the network port’s Gateway setting (see Section 8.2, Configuring the Network (LAN) Port, on page 65).
Parameter <IP address> is a string specifying the address of the gateway server, using IP dot notation.
This setting is only meaningful when DHCP is OFF.
The query form returns the value of the Gateway setting when DHCP is OFF and returns the dynamically
provided gateway address when DHCP is ON.
8.7.3.108 SYST:COMM:SOCK:KEEP <seconds>
Example command: SYST:COMM:SOCK:KEEP 3600
Query form: SYST:COMM:SOCK:KEEP?
Alternate parameter: DEF, MIN, MAX
Sets the network port’s keep-alive timeout setting.
Parameter <seconds> is the keep-alive timeout value, in seconds.
This setting determines the length of time, in seconds, after which the socket is automatically closed if there is
no activity. At power-on the setting defaults to 60 seconds. If a different timeout is desired, the settings can be
changed using this command. If the setting is set to 0, the keep-alive timeout will be disabled.
The keep-alive timeout may be useful if a connection is dropped unexpectedly, such as if the network or cli-
ent fails. The network socket of the Super-Thermometer might otherwise remain open indefinately, and no
subsequent socket connection request would be accepted. With the keep-alive timeout enabled, if no activity
is detected during the timeout period, the socket will close automatically, and a new connection will then be
accepted.
In applications where there might normally be a long period between messages, it might be necessary to in-
crease or disable the keep-alive timeout to prevent the connection from being closed automatically.
