Housing
The V290iA is housed in a case designed to be resistant to pressure, moisture, and
extremes in temperature. The V290iA is not intended for field servicing.
The housing is fully sealed, and uses a pressure valve to equalize pressure inside and
outside the housing while holding out water molecules. The housing provides a fully
stable environment with the ability to resist moisture even in full immersion. The
housing is held in place by locking screws to maintain a proper seal.
The Ethernet and Serial interfaces use a rugged design to protect the interface pins.
The interface panel is located on the bottom of the V290iA when it is mounted in the
standard way, and the RF antenna connection is on the top.
A 100° cable is attached to both halves of the housing to permit ease of service for a
field technician. A console port for the Cisco router is available on the interface panel.
Heating and Cooling
In order to maintain the proper working temperature, the V290iA has a temperature
control system included inside the housing. This temperature control system allows the
V290iA to operate in outdoor installations, maintaining a temperature range
between -30° C and 60° C.
