The NL900PRO transceiver is a Frequency-Hopping Spread Spectrum FHSS) radio designed for license-free
operation in the 900 MHz ISM band. The radio sustains a standard asynchronous serial data stream
between two or more radios out of the box. Housed in a compact and rugged die-cast enclosure, the radio
is equipped to replace miles of serial cable using a selectable RS232, RS485, or RS422 interface.

The NL900PRO uses Frequency Hopping Spread Spectrum modulation, where the units "hop" from frequency
to frequency many times per second using a specific hop pattern applied to all the transceivers in the same
network. A distinct hopping pattern is provided for each Channel Number, thereby allowing multiple
networks to co-exist in the same area without interference.
NL900PRO transceivers operate in a Point-to-Point or Point-to-Multipoint, Client-Server architecture. One
transceiver is configured as a Server and there can be one or many Clients. To establish communication
between transceivers, the Server emits a beacon and upon detecting a beacon, RF link is established with
the Client s).
NL900PRO implement a proprietary communication protocol to provide secure data transmissions. The use
of FHSS technology ensures data reliability over long distances. Use of license free frequency bands ensure
that the units are ready for use with no further certification requirements.
Each unit is small and easily portable for use in mobile and temporary settings as well as for fixed
installations. The NL900PRO configuration software enables custom configurations based on unique
application requirements.

The RS-485 interface uses a Differential Data Transmission that can help nullify the effects of ground shifts
and induced noise signals that can appear as common mode voltages on a network.
The NL900PRO implements a RS-485 2-wire Half Duplex) multi-drop interface. Typically, a RS-485 bus will
consist of a master and several slaves. The nodes will have unique addresses and can send addressed
packets to specific nodes. Because the bus is half duplex, no two nodes should try to talk at the same time.
The NL900PRO does not have a RS-485 address, therefore, it will transmit all RS-485 traffic over the RF.
Conversely, as soon as a NL900PRO receives a packet over the RF, it will transmit the packet over the RS-
485 bus.

Flow control refers to the control of data flow between the host and the NL900-PRO. It is the method used to
handle data in the transmit/receive buffer of the NL900-PRO interface, and determines how data flow
between the host and the NL900-PRO is throttled. Often in serial communication, one device is capable of
sending data much faster than the other can receive. Flow control allows the slower device to tell the faster
device to pause and resume data transmission. Flow control CTS and RTS are used by the NL900-PRO and
its Host, locally - NOT over t e air . Therefore, one NL900-PRO cannot tell the other to slow down or speed
up as is mentioned above in the paragraph).
When the RTS Enable option is selected on the Configuration Utility, the transceivers use hardware flow
control to regulate data flow. While using hardware flow control, the transceiver that is ready to receive
data sends a Clear To Send signal to its host or the device it is connected to). On the other hand, when a
transceiver has something it wants to send to its host, it checks the state of Ready To Send and if it is logic
low, will send data to its host. If RTS is logic high, it will not send data to its host. These signals are sent
apart from the data itself on separate wires.

C H A P T E R 3 - S E R I A L I N T E R F A C E 8
Note: CTS is always enabled by default. RS-485
Interface does not support Hardware flow control.
DESIGN TIP
Can I implement a design using just Txd, Rxd and Gnd Three-wire Interface)?
Yes. However, it is strongly recommended that your hardware monitor the CTS pin of the
radio. CTS is taken High by the radio when its interface buffer is getting full. Your
hardware should stop sending at this point to avoid a buffer overrun and subsequent loss
of data).
You can perform a successful design without monitoring CTS. However, you need to take
into account the amount of latency the radio adds to the system, any additional latency
caused by Transmit Retries or Broadcast Attempts, how often you send data, non-delivery
network timeouts and interface data rate. Polled type networks, where the Server host
requests data from the Client host and the Client host responds, are good candidates for
avoiding the use of CTS. This is because no one transceiver can monopolize the RF link.
Asynchronous type networks, where any radio can send to another radio at any point in
time, are much more difficult to implement without the use of CTS.

The NL900PRO utilizes a Server-Client network where all Clients synchronize their hopping to the Server. The
Server transmits a beacon during the first 1 ms of every hop 20 ms). The Client transceivers listen for this
beacon and upon hearing it assert their In Range Low and synchronize their hopping with the Server.
Each network should consist of only one Server and there should never be two servers on the same RF
Channel number in the same coverage area as the interference between the two servers will severely
hinder RF communications. For those applications requiring collocated servers, Raveon Technologies
recommends using the Sync-to-Channel feature which is further explained in the Sync-to-Channel
Appendix.
M O D E S O F O P E R A T I O N
The NL900PRO has three different operating modes; Receive, Transmit, & Command Mode. If the
transceiver is not communicating with another radio, it will be in Receive Mode actively listening for a
beacon from the Server. If the Client determines that the beacon is from a server operating on the same
RF Channel and System ID, it will respond by asserting In Range Low. A transceiver will enter Transmit or
Command mode when the OEM Host sends data over the serial interface.
T R A N S M I T M O D E
All packets sent over the RF are either Addressed or Broadcast packets. Broadcast and Addressed delivery
can be controlled dynamically with the API Control byte and corresponding on-the-fly commands. To
prohibit transceivers from receiving broadcast packets, Unicast only can be enabled.
A D D R E S S E D P A C K E T S
When sending an addressed packet, the RF packet is sent only to the receiver specified in destination
address. To increase the odds of successful delivery, Transmit retries are utilized. Transparent to the OEM
Host; the sending radio will send the RF packet to the intended receiver. If the receiver receives the packet
free of errors, it will return an RF acknowledge within the same 20 ms hop. If a receive acknowledgement
is not received, the radio will use a transmit retry to resend the packet. The radio will continue sending the
packet until either 1) an acknowledgement is received or 2) all transmit retries have been used. The
received packet will only be sent to the OEM Host if and when it is received free of errors.
B R O A D C A S T P A C K E T S
When sending a broadcast packet, the RF packet is sent out to every eligible transceiver on the network. To
increase the odds of successful delivery, Broadcast attempts are utilized. Transparent to the OEM Host, the
sending radio will send the RF packet to the intended receiver s).
Unlike transmit retries, all broadcast attempts are used; regardless of when the RF packet is actually
received and without RF acknowledgements. If the packet is received on the first attempt, the receiver will
ignore the remaining broadcast attempts. The received packet will only be sent to the OEM Host if and
when it is received free of errors.

When a transceiver is not in Transmit or Command mode, it will be in Receive Mode listening for data.
While in Receive Mode, subsequent data of up to 80 bytes can be received every hop 20 ms).
C O M M A N D M O D E
A radio will enter Command Mode when data is received over the serial interface from the OEM Host and
contains the “AT+++” Enter AT Command Mode) command. Once in Command Mode, all data received by
the radio is interpreted as command data. Command Data can be either EEPROM Configuration or On-The-
Fly commands.

Topology refers to the shape of a network, or the network's layout. How different nodes in a network are
connected to each other and how they communicate, is determined by the network's topology. The
NL900PRO supports a Point-to-Point and a Point-to-Multipoint network topology.

Point-to-Multipoint systems have one base station, or access point, that controls communications with all of
the other wireless nodes in the network. This allows for the creation of a wireless network consisting of
multiple nodes. By programming each NL900PRO with a network specific Channel Number and System ID
multiple networks can be created.

1) Client/Server: Designates NL900PRO type. In each network, there must be only one Server. All
other NL900PRO units must be programmed as Clients. The number of Clients in the network is not
limited; however, if performance diminishes, consider additional RF Networks.
2) Interface Baud Rate: This defines the baud rate used for communicating with the NL900PRO over the
serial interface. The RF baud rate is fixed at 76.8 Kbps and is independent of the Interface Baud Rate. The
default baud rate setting is 57600 bps unless the units have been pre-configured by Raveon Technologies.
T e
Interface Baud Rate setting of t e NL900PRO must matc t e Baud Rate setting of its ost
device.
3) C annel Number: A number that designates an independent network of NL900 units. Up to 32
independent networks can be created. The valid range of values for this field is 16 to 47.
4) Max Transmit Retries (For Clients and Servers in Point-to-Point networks only): This value
represents the maximum number of times a particular data packet will be transmitted unsuccessfully, or
without an acknowledgement, before the NL900PRO discards the packet. The default value is 16
attempts. If communication is lost and the Client's Link LED is on, try increasing this value in small
increments until communication is reestablished.
Note: This value is always associated to Client radios and Server radios in Point to Point Mode. The valid
range of values for this field is 1 to 255.
5) Broadcast Attempts (For Servers in Point-to-Multipoint networks only): This value represents
the number of times a data packet will be transmitted by the Server NL900PRO. The default value is 4
attempts. If communication is lost and the Clients' Link LED is on, try increasing this value in small
increments until communication is reestablished. The valid range of values for this field is 1 to 255.
6) System Identification: A number from 0 to 256 that provides added security to each independent
network of NL900PRO units. The System ID is used in conjunction with the Channel Number and serves as
an RF password to maintain secure transfers of data. The combination of the Channel Number and System
ID must be unique to each network of NL900PRO to establish communication. Multiple Servers in the same
coverage area must be programmed with different Channel Numbers to prevent inoperability of the networks.
The System ID will not prevent inoperability that occurs from locating multiple Servers with the same
Channel Number in the same coverage area.
Note: Separate Collocated NL900PRO networks must operate on different Channel Numbers. All units in a
given NL900PRO network must have identical Channel Numbers and System IDs.
7) Data Encryption Key: Encryption is the process of encoding an information bit stream to secure the
data content. The DES algorithm is a common, simple and well-established encryption routine. An
encryption key of 56 bits is used to encrypt the packet. The receiver must use the exact same key to
decrypt the packet; otherwise garbled data will be produced.
8) Destination Address: The MAC Address of the remote NL900PRO in a Point-to-Point network. Used to
optimize Point-to-Point communications by utilizing RF Acknowledgement.
9) Firmware Version: Displays the NL900PRO's firmware version.

C H A P T E R 5 - N L 9 0 0 P R O S E T T I N G S 12
10) MAC Address: A unique 6 Byte, IEEE 802.3 Ethernet address assigned by Raveon Technologies to each
NL900PRO.
RAD I O F E A T U R E S
1) Data Encryption: Enables the Data Encryption Key. All NL900s in the same network must have the
same encryption setting.
2) RTS Enable: Enables the Request To Send control line. When enabled, enables Hardware Flow Control.
3) Parity: Needs to be enabled if host requires even or odd parity and 8 data bits. This is considered as
9-bit mode. Note: Enabling Parity cuts the overall throughput into half.
4) Full Duplex: This mode restricts Client radios to transmitting on odd numbered frequency hop bins and
the Server to even numbered frequency hop bins. Though the RF hardware is still technically half duplex, it
makes the transceiver seem full duplex. This can cause overall throughputs to be cut in half. Note: All
transceivers on the same network must have the same setting for Full Duplex.
5) Modem Mode: Full modem handshaking is supported by the transceivers when Modem Mode is
enabled. Modem Mode is incompatible with RS-485Interface. Enables, DCD, DTR, DSR and Ring Indicator
control lines.

radio will send data only to the radio whose MAC matches that specified in the
Destination Address field point-to-point).
2 If the Destination Address field is set to FF FF FF FF FF FF on a client radio, it will be set
to auto destination mode & transmit to the radio whom it last received a packet from.
3 If the Destination Address field is set to FF FF FF FF FF FF on a server radio, it will be
set to Broadcast mode & transmit to all available clients point-to-multipoint).
