PC connected directly to an ETH port
The default IP address for access via ETH ports is 192.168.169.169.
Set a static IP address in PC to 192.168.169.0/24 (e.g.192.168.169.250, subnet mask
255.255.255.0).
Important
When you change the RipEX2 ETH address to a different IP address/mask, the IP address
of your PC might be necessary to be updated to match the same subnet (mask).
Note
https - For security reasons the http protocol with ssl encryption can be used for the commu-
nication between the PC and RipEX2. The https protocol requires a security certificate. You
must install this certificate into your web browser. The first time you connect to the RipEX2,
your computer will ask you for authorisation to import the certificate into your computer. The
certificate is signed by the certification authority RACOM s.r.o. It meets all security regulations
and you need not to be concerned about importing it into your computer. Confirm the import
with all warnings and exceptions that your browser may display during installation.
Warning
Before you start any configuration, make sure only one unit is powered ON, otherwise a different
radio modem could reply to your requests! (In default settings: all units share the same IP ad-
dress and are in Bridge mode - which means, they can connect together over the air and create
unwanted responds.)
Note
If you do not have the USB adapter or you have forgotten the password, you can reset the
access parameters to defaults, see
Section 2.2.9, “HW button” .
1.1. Bench testing
Before installing a RipEX2 network in the field, a bench-test should be performed in the lab. The RipEX2
Demo case is great for this as it contains everything necessary: 3× RipEX2 unit, Power supply, dummy
load antennas, etc.
If you use your own installation for lab tests, do not forget:
• A dummy load or an actual antenna with 50 ohm impedance should be connected to the RipEX2
• Minimum RF output must be set to avoid overloading the dummy antenna and to keep the received
signal at reasonable level, between -40 and -80 dBm.
• The power supplies must meet the requirements given in the specifications. Make sure the power
supplies do not generate interference in the radio channel and that they can handle very fast changes
in the load when RipEX2 switches from reception to transmission and back.
