The PKG-T RF Modem provides a wireless link between devices out-of-box and without

configuration. If more advanced features are needed, the XStream RF Module and Telephone

Module can be configured via the DB-9 connector or a wireless link.

The Data Path Switch is controlled by the

and lines of the DB-9 connector. In the PKG-

T’s RF Modem’s default state (when nothing is attached to the DB-9 connector), data is routed

between the RF module and the telephone module. In this case, the Telephone Module

communicates directly with a remote RF Modem and receives commands through a wireless link.

+10V -10V DB-9 connects to Telephone Module for configuration.

-10V (default state) -10V / +10V (default state)

RF Module and Telephone Module are connected to each other and not

to the DB-9 connector.

This is the default state of the RF Modem

(when DB-9 is not connected).

Refer to the RF Module Configuration [p15] and Telephone Module Configuration [p20] sections

for more information about configurations of the on-board Telephone and RF Modules.
