Note The PC/104-Plus standard requires that the PCI bus and the ISA bus use keying features in the standard
stacking headers to guarantee proper module installation. On the PCI bus, pin D30 is removed and its
opening is plugged. On the ISA bus, pin C19 and pin B10 are removed, and their openings are plugged.

Antenna Connector

On the radio card, two ultra-miniature coaxial connectors (U.FL connector) connect the coax cables
between the WMIC and the external antenna connectors. Two connectors support antenna diversity.
The cable should be as short as possible to minimize the loss in strength of the RF signal. The cable
carries the RF signal from the antenna to the low noise amplifier (LNA) on the receiver and carries the
RF signal from the power amplifier (PA) to the antenna that radiates the RF signal.
There are many antenna connector families. The Cisco RP-TNC antenna connector can be used to
support standard antennas.

WMIC Console and Fast Ethernet Ports

Cisco 3200 Series router cards do not support any ISA bus signals. The PCI bus connector supports
communication between the Cisco 3200 Series router card and the PCI Serial Mobile Interface Card
(SMIC) and between the SMIC and the Fast Ethernet Switch Mobile Interface Card (FESMIC).
In a Cisco Rugged Enclosure, the WMIC communicates with the router through the WMIC Fast Ethernet
interface. The WMIC Fast Ethernet ports are connected internally to Fast Ethernet ports that provide a
communications link with the router.
The WMIC interfaces are configured through a WMIC console port.
