Connecting the Chamber to a Client PC
Connect the mmWave OTA Validation Anechoic Chamber to a client PC using a direct
connection.
Tip
For best results, dedicate one Ethernet port for the communication and connect
the Ethernet cable from that port directly to the client PC to avoid slow hubs or
switches.
Note
The Ethernet port on the client PC must use the same subnet as the host
chamber. For example, if you use the default fixed IP address for the chamber
(
192.168.2.10
), use
192.168.2.1
for the client PC. If you are connecting
multiple clients to the host chamber through a switch, each client must have a unique
IP address on the same subnet as the host.
Verify the Connection
To verify that the chamber is connected to the client PC, open a Command Prompt window
and enter
"ping 192.168.2.10"
.
