RF Pass-Through
The RF pass-through feature enables the Motorola ML910™ Rugged Notebook Computer
to receive and transmit radio signals through external antennas for better coverage or
range, as compared to using its internal antennas, which typically are impaired by
in-vehicle shielding. RF pass-through operation depends on having the required RF
pass-through option (ZA00618AA) and certain wireless options installed in the ML910, as
well as a vehicle docking station that supports RF connectivity to the ML910. The presence
of the RF pass-through option is noted on a label affixed to the underside of the ML910.
The wireless options that support RF pass-through are: embedded Wireless Wide Area
Network (WWAN) modules, such as one of the public carrier modules or the Motorola
Private DataTAC PRM240 modem, and/or a GPS receiver module.
1 Figure 1 shows the
RF pass-through connectors (labeled as 3 and 4) which refer to the GPS antenna
connector and WWAN module antenna connector, respectively. Note that these
connectors are present on all ML910 notebooks regardless of the associated options
being installed.
RF pass-through is a standard feature on the high tier ML910 Vehicle Docking Station
(VDS or “dock”), and is available on compatible
2 ML900 docks by installing the RF
pass-through retrofit kit. The ML910 RF pass-through feature is not backward compatible
with the ML900 high tier dock's standard RF pass-through facility (located on the deck of
that VDS) that is intended for ML900 notebooks only.

1 The ML910’s 802.11 Wireless Local Area Network (WLAN) feature includes an internal
antenna and does not utilize RF pass-through.
2 RF pass-through retrofit kit is compatible with VDS models DDN7501B and C and
DDN7502B and C, but not DDN7501A or DDN7502A.
