Figure 6-1 shows the WMIC header and bus locations.

Figure 6-1 WMIC Header and Bus Locations

Note The PC/104-Plus standard requires that the PCI bus and the ISA bus utilize keying features in the

standard stacking headers to guarantee proper module installation. On the PCI bus, pin D30 is removed

and the D30 opening is plugged. On the ISA bus, pin C19 and pin B10 are removed, and the C19 and

B10 openings are plugged.

Antenna Connector

On the radio card, there are two ultra-miniature coaxial connectors (U.FL connector) that are used to

connect the coax cables between the WMIC and the external antenna connectors. Two connectors are

used to support antenna diversity.

The cable should be as short as possible to minimize the loss in strength of the radio frequency (RF)

signal. The cable carries the RF signal from the antenna to the low noise amplifier (LNA) on the receiver

and transmits the RF signal from 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 Cisco 3200 Series router card and the Fast Ethernet Switch Mobile Interface

Card (FESMIC) and Serial Mobile Interface Card (SMIC).

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.
