• Mobitex radio
A Mobitex radio allows the PTC to communicate
via the wide-area Bell-South Mobile Data digital
communication network.
A wide-area network is a radio network that supports
data communications across a broad area, such as a
city, a state, or even nationwide.
Your PTC’s application program
controls the radio. Refer to your
application’s manual for details on
using the radio to transmit and
receive data.
The PTC uses its radio to communicate with a host
computer. Via the radio, the PTC can send data to the
host, and the host can send data and instructions to
the PTC.
Antenna
If the PTC-2124 contains an expansion module and a
radio, the radio antenna is located inside the
expansion module.
Fold the antenna against the PTC
when the unit is not in use. If the PTC contains a radio but not an expansion
module, a single external articulating 800 MHz, 900
MHz, or 2.4 GHz antenna is attached to the blank
module cover on the right side of the PTC. The
articulating antenna bends at a 90
× angle at its
knuckle and rotates 360
°
degrees around its mounting
point. To achieve maximum signal strength for both
transmission and reception, make sure the antenna is
perpendicular to the ground, regardless of whether
you are holding the PTC or it is installed in a
communication cradle.
