System Setup
These instructions apply to setup using the front panel
LCD. If you will be using Wireless Designer for setup,
instructions are in the help files supplied with the soft-
ware.
Install Receiver Modules
Turn power off on the DR mainframe. Install the mod-
ules as needed. Any module can be installed in any
position in the mainframe assembly. When the power
is turned on, the modules will be detected during the
bootup sequence and an icon for each one will appear
on the LCD.
Generate Encryption Key
On the receiver LCD, navigate to the KEY MANAGE-
MENT item in the Top Menu and press the encoder to
enter the setup screen.
In this setup screen, the type of encryption key policy
can be set, a new key generated or the existing key
can be deleted.
The encryption key policy can be configured as:
s 0%23)34%.4
s /.%4)-%+%9
A PERSISTENT key will remain in receiver and trans-
mitter memory until it is replaced with a new key or
manually deleted using WIPE KEY in the menus.
A ONE-TIME ONLY key is used for maximum secu-
rity. The key exists only as long as the power on both
receiver and transmitter remains on during a single
session. If a transmitter is powered off, but the receiver
has remained turned on, the key must be sent to the
transmitter again. If the power is turned off on the
receiver, the entire session concludes and a new key
must be generated and sent to all transmitters.
In either key policy, there are 256 “instances” available
each time a new key is generated. “Instance” refers to
a transfer of the key from receiver to transmitter. Each
instance contains a unique key. The number of instanc-
es is reduced each time a key is transferred. When
the number of instances reaches 10, a warning will be
displayed on the LCD.
Select the NEW KEY option and press the encoder to
enter the setup screen.
NOTE: It is generally more convenient to use a
PERSISTENT key during setup, since power may
be need to be cycled on and off on the transmitters
or receiver until the system is completely set up.
The stored key can be deleted manually with the WIPE
KEY option.
Initial Transmitter Setup
Attach the antenna and install the batteries into the
transmitters that will be used. Turn the power on and
observe the BATT LED on the transmitter. Verify that
the batteries are fresh or fully charged (the LED will
glow green with good batteries).
Transfer Encryption Key to Transmitters
On the receiver LCD, navigate to the KEY TRANSFER
item in the Top Menu and press the encoder to enter
the setup screen.
YES indicates the transmitter is connected
Connect the transmitter with the key cable and press
the encoder to start the transfer. The LED on the top
right corner of the keypad will glow blue when the key
has been transferred successfully.
NOTE: The key can be transferred with the
transmitter either fully powered up or in the standby
mode with the RF output turned off.
