Ethernet cable
Wi-Fi Antenna
The Wi-Fi cabling and antenna must meet the following requirements:
• 50 ohm impedance
• RP-SMA (Male) connector
• Antenna designed for Wireless LAN or Wi-Fi
• Recommended antenna frequency rating: 2.4 GHz
• Recommended antenna bandwidth rating: 1.0 GHz
The Wi-Fi performance specifications of the RAM-9000 are shown in the table below:
Ethernet cable
If you are connecting to the unit via the Ethernet port, you will need a straight or crossover minimum category 5
cable with two 8-pin RJ45 connectors on each end.
To visually confirm that Ethernet cabling was done properly, check the LED indication on the Ethernet port of the
unit. The link LED should be on when the correct cable is used.
Note: A shielded cable is required to fully meet EMC standards.
