mDNS and DNS-SD are two additional protocols: Multicast DNS and DNS Service
Discovery. They are used for device communication in zero configuration networks
working without DNS and DHCP
Ping Client
Ping is a utility that verifies the connection between the LXI-compliant instrument and
another device. The ping command uses the
ICMP
echo request and echo reply pack-
ets to determine whether the LAN connection is functional. Ping is useful for diagnos-
ing IP network or router failures. The ping utility is not password-protected.
To initiate a ping between the LXI-compliant instrument and a second connected
device:
1. Enable "ICMP Ping" on the "Advanced LAN Configuration" page (enabled after an
LCI).
2. Enter the IP address of the second device
without the ping command and with-
out any further parameters
into the "Destination Address" field (e.g.
10.113.10.203
).
3. Select "Submit".
How to Change the GPIB Instrument Address
In order to operate the instrument via remote control, it must be addressed using the
GPIB address. The remote control address is factory-set to 20, but it can be changed if
it does not fit in the network environment. For remote control, addresses 0 through 30
are allowed. The GPIB address is maintained after a reset of the instrument settings.
Setting the GPIB address
1. On the R&S
ZNL/ZNLE, press the [SETUP] key.
2. Press the "N Remote" softkey.
3. In the "N Remote" dialog box, select the "GPIB" tab.
4. In the "GPIB Address" field, enter a value between 0 and 30.
Remote command:
SYST:COMM:GPIB:ADDR 18

How to Operate the Instrument Without a Network
To operate the instrument without a network connection either temporarily or perma-
nently, no special measures are necessary. Windows automatically detects the inter-
ruption of the network connection and does not set up the connection when the instru-
ment is switched on.
