XTEND®-PKG
RF MODEMS
900 MHz radio modems oer long-range performance, advanced networking
and simple out-of-the-box operation with multiple data interface options
Digi’s XTend-PKG RF modems provide everything you need
for out-of-the-box serial cable replacement, enabling quick
wireless connectivity of electronic devices across a broad
range of applications. Simply feed data into one modem
and the data is transported to the other end of a long
range wireless link. Data security is provided by 256-bit AES
encryption (128-bit AES is available outside of North America).
If more advanced functionality is needed, the modems
support an extensive set of AT and binary commands.

Quick Start Guide
XTend-PKG-U™ USB RF Modem
Create a long range wireless link in minutes.
Connect Hardware
To install the modem and test modem range, you need:
• One XTend-PKG-U™ USB RF Modem
• One XTend-PKG-R™ RS-232/485 RF Modem
• Accessories (USB cable, Loopback Adapter, 2 Power Supplies, 2 RPSMA Antennas)
• One Windows computer that has an available USB port and is loaded with the following
software: X-CTU software and USB RF Modem drivers.
Hardware Setup
1. Verify PKG-U RF Modem ("Radio1") was successfully connected to the USB port of the PC.
2. Attach serial loopback adapter to the female DB-9 serial connector of the PKG-R RF Modem
(Radio2). The serial loopback adapter configures Radio2 to function as a repeater
by looping data back into the modem for retransmission.
3. Configure Radio2 (PKG-R RF Modem) for RS-232 operation
using its built-in DIP Switch (Switches 1, 5 & 6 are ON (up)
and the remaining switches are OFF (down)).
4. Attach RPSMA antennas to Radio1 & Radio2.
5. Power Radio1 & Radio2 through their respective power connectors. Radio1
can be powered through the USB connection (Bus power mode); however,
its power output is limited to 100 mW.

Install Software
Install X-CTU Software
Go to the X-CTU softwre page at www.digi.com/xctu and launch the latest X-CTU installer. Follow the
prompts on the installation screens.
Install USB RF Modem Drivers (Hardware USB Bus and Virtual Com Port drivers)
Go to www.digi.com/xctu and click the Drivers link. Under General Drivers, select the apporpriate
operating system to download drivers.
Verify Driver Installations
1. Connect the PKG-U RF Modem "Radio1" to the USB port of a PC.
An illuminated bottom-left red LED indicates a successful USB link.
2. Launch the X-CTU Software and select the PC Settings tab.
(Start > All Programs > Digi > X-CTU)
3. In the Com Port Setup section of the PC Settings tab, select the PKG-U
RF Modem that is connected to the USB port. Com ports dedicated
to a USB RF modem have ”Digi PKG-U” in the com port name.
This PC com port will be used when executing the range test.

Congure Serial Port-Modem Commuications
Configure a PC serial port to communicate with the modem:
1. Launch X-CTU Software:
2
Click the PC Settings tab. From the dropdown list, select the PC com port
2
that will be used to connect to Radio1. Com ports dedicated to USB RF Modems
will always begin with “Digi PKG-U...”.
Select the Baud rate that matches the default RF data rate (over-the-air
3
baud) of Radio1. Use default values for remaining fields.

By default, the XTend-PKG-U RF data rate
is set to 9600 baud (bps).
Remaining Default Values:
Flow Control = NONE
Data Bits = 8
Parity = NONE
Stop Bits = 1
Determine the RF Modem Range
1. Click the Range Test tab.
(Optional) Check the check box in the RSSI section to enable display of signal strength.

Tips and Suggestions
Modify Interface Data Rate of RF Modem (Optional)
OEMs and integrators can interface with XTend RF Modems at different baud
rates than the modem defaults. To change the modem’s serial interfacing rate,
first select the PC com port baud rate that matches the modem’s default [steps
1-2 below]. Then change the baud rate of the modem itself [steps 3-7]. Finally,
select the baud rate of the PC com port to match the newly set baud rate of the
modem [step 8].
1. Set up a connection to a PC by following the steps of the Hardware Setup
instructions on page 1.
2. Select the PC Com port baud rate that matches the RF Modem's fixed RF
data rate by following steps in Configure PC-Modem Communications on page 3.
3. In the X-CTU Software, click the Modem Configuration tab.
4. Click the Read button to view currently stored parameter values.
5. In the Commands/Parameters hierarchical tree, open the Serial Interfacing Options
folder by selecting its plus (+) sign.
6. Select the Baud Rate entry, then select a desired baud rate from the
dropdown list.
7. Click the Write button to save new settings to non-volatile memory.
8. Click the PC Settings tab, then select the value from the Baud dropdown list
that matches the newly set baud rate. This configures the PC Com Port
to communicate at the new baud rate.
Create a Wireless Link between Devices
A pair of RF Modems can be used in lieu of a cable to create a wireless link
between devices. The topology below illustrates a basic wireless strategy that can
be used when connecting to target devices such as automatic meter readers, fleet
management devices, remote weather stations and a host of other applications.
When connecting devices, consider the following:
• Use the male-to-male NULL modem adapter to connect Radio2 to a
target serial device [Figure 6]. Signals crossover inside the adapter.
• To verify cabling is functioning properly, insert a female-to-female
NULL modem adapter in place of Radio1 and Radio2, then test
communications without the RF modems in the link.
