Running Communications

With the Host

The PDT 3400 communicates with the host through the IrDA interface while the unit is in
the CRD 3400 or VCD 3400 cradle.
Note on Cradle Communications
The vehicle cradle "bus" is always available available to an application for communications
via the IrDA interface. The office cradle can be chained to other office cradles and therefore,
prior to transmitting to the host, the cradle "bus" must be "locked" before an application
transmits data. Applications can receive data from the bus without locking the bus.
The PDT 3400 SDK provides a utility, PDTSET, which includes an option for locking the bus
on (PDTSET BUS=ON) and unlocking the cradle bus (PDTSET BUS=OFF) when
communicating through IrDA using the INT 14 interface. When communicating via the
IRCOMM interface, the bus is locked using API calls defined in Chapter 9 of the PDT 3400
System Software Manual.
Refer to Chapter 3, Hardware Installation, for instructions on setting up the cradles for
communications.

With Printers

The PDT 3400 communicates with IrDA-compliant devices (e.g., Comtec and O'Neill
printers) through the IrDA interface in the base of the unit. From a maximum distance of 1
meter, point the PDT 3400 at the IrDA-compliant printer and run the application's print
function.

In a WWAN Network

PDT 3400s equipped with an integrated WWAN radio card can communicate on the network
supported by that card. For more information, refer to the documentation for the specific
WWAN radio in your PDT 3400.
