1. Overview
The Daisy Wireless Modem is a secure, high-performance, long-
range wireless access card and GPS transponder. Two data
interfaces are available, transparent-link mode and Raveon’s WMX
Wireless Packet Format. Modem operation is virtually transparent
to the user and the configuration of the modem is done easily
through the user serial port.
As a GPS transponder, configuration is as simple as setting a report
rate. Many options are available to create a customized GPS transponder by adjusting reporting rules
and detail levels of GPS reports.
For security, AES-128 encryption is available.
While easy to use out-of-the-box, the Daisy Modem’s programmability makes it extremely versatile.
Most parameters may be reconfigured to optimize for specialized operations, extended range or higher
data throughput.
1.1 Input and Output
1.1.1. Universal Wireless Radio Connector
Raveon utilizes a universal connector configuration on many of its radio modem modules, so the Z50 is
plug-in compatible with dozens of other radio modems. The UWRC connector pint-out is as shown

The primary connector is fully pin-for-pin compatible with M8 UHF, VHF, 220MHZ modems. V50 ISM
band radio modems.
1.1.2. LED
By default, the LED will indicate the following:
Green: Radio has received a packet
Red: Radio is transmitting a packet
Flashing Orange: GPS is locking (flashing will cease when GPS has locked)
Many commands modify the operation of the LED, including disabling it entirely.
1.1.3. RF Antenna Connection
The RF Antenna Connection is an MMCX
1.1.4. GPS Antenna Connection
If installed, the GPS Antenna Connection is a u.FL (sometimes known as IPEX)
2. Configuring the Daisy ISM
2.1 Overview
The UART serial port on the unit is used to send and receive data over the air, as well as to configure the
RF modem. In standard transparent-link operation, the user sends serial data into the TxD pin of the
user port, and this data is transmitted over the air. Received data from another RF modem is output to
the user via the RxD pin of the user port. This is the default operating condition of the RF modem. No
special characters, hardware control lines, or timing is required to operate the Daisy Modem.
By default, the serial port is set to 38400 baud, 8 data bits, 1 stop bit, no parity bit.

RV-M50-E Technical Manual

If the Daisy is configured as a GPS transponder, the serial port need not be connected to anything. The
internal GPS will initiate the transmissions of position and status. The serial port may be connected to
receive other GPS reports or send and receive additional data.
There is also a Command Mode used to program and configure the modem. In the Command Mode, the
modem accepts commands via the serial port TxD pin. The commands can be used to change certain
internal parameters of the modem as well as to read-out the current configuration and diagnostic
statistics.
The modem also supports Raveon’s Wireless Modem Exchange (WMX) protocol for commanding and
messaging. WMX is ideal for fully automated control and tighter integration. For more information, see
the WMX Protocol Description document and the Raveon Tech Note “Rapid Radio Configuration using
WMX”.
2.2 Command Mode
Command Mode is used to program and configure the modem. This mode is separate from data mode
and will not transmit received data over-the-air, instead executing commands detailed in this manual.
1.1.5. Command Mode Encoding and Line Format
In Command Mode, all characters are ASCII encoded. All output lines will use the standard network line
ending, CR+LF (ASCII 0x0D followed by ASCII 0x0A).
Inputs lines may use either CR, LF or CR+LF line endings.
1.1.6. Entering Command Mode
The modem may be put into a Command Mode, by entering a sequence of three plus characters (+++),
called the Entry Sequence.To keep the modem from unintentionally entering the Command Mode
because of the Entry Sequence occurring in a stream of data entering the modem, there must be a
pause in the data stream before the Entry Sequence as well as a pause afterwards. If either pause is
missing, the modem will not enter the command mode. The pause length is configurable, by default it is
500ms.
When the modem first enters the Command Mode, it will output the base model number along with the
OK sequence:
RV-M50
OK
Once in command mode, the instructions in the following sections can be followed to continue radio
configuration.
1.1.7. Exiting Command Mode
To exit command mode and return to data mode, the command EXIT may be used.
Alternatively, command mode will timeout after a configurable amount of time, by default 60 seconds.

RV-M50-E Technical Manual

2.3 Using Commands
To execute a command, send the command name and any parameters separated by spaces, followed by
a line ending. For example, to use the ATDT command to set the destination address to 1234, send:
ATDT 1234<LF>
Some commands may output result information on lines following the command, but the output will
always terminate with either the OK sequence (introduced in the previous section) or the ERROR
sequence (ERROR<CR><LF>).
Some commands may have different results depending on the number of parameters. In general, a
command that sets a parameter(s) can read back its values by issuing the command with no parameters.
To get on-line help with a command, enter the command with a question mark at the end.
To see a list of all commands, use the HELP command.

the unit reports at the TXRATE intervals if it
has moved this distance since the last
