SPECIFICATIONS RS-232
RS-232 is a single-ended serial data transmission protocol. The RS-232 signals are represented by
voltage levels with respect to a system common (power/logic ground). The “idle” state (MARK) has
the signal level negative with respect to common and the “active” state (SPACE) has the signal level
positive with respect to the common.

INTERFACINg TO OTHER RS-232 EqUIPmENT
The CL2510 is a DCE (Data Communications Equipment) device with limited handshaking. Typically
devices like PCs are considered DTE (Data Terminal Equipment) devices while peripheral devices are
classied as DCE. A DCE device can be interfaced to a DTE device using a straight through serial cable.
When interfacing two DCE or two DTE devices together, a null modem cable is required to cross the
respective input and output signals.
DTE TO DCE AND DCE TO DCE INTERFACES
* Design Tip: When using a pair of CL2510s to connect a PC to a peripheral unit, if you previously used a
straight through cable to connect your PC to your peripheral device, you’ll need to use a straight through cable
between the PC and the CL2510 and a null modem cable between the other CL2510 and the peripheral device.
HARDWARE FLOW CONTROL
Flow control refers to the control of data ow between the host and the CL2510. It is the method used to
handle data in the transmit/receive buffer of the CL2510 interface, and determines how data ow between
the host and the CL2510 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 CL2510 and its Host, locally - NOT
over the air. Therefore, one CL2510 cannot tell the other to slow down or speed up).
The transceiver uses CTS to indicate the state of its input buffer. The OEM host uses RTS to indicate when
it’s able to receive data from the transceiver. When RTS Enable is set on the transceiver, the transceiver will
monitor RTS and will only transmit data out the serial interface when RTS is low. For this reason, the OEM
should not set RTS Enable on the CL2510, unless the OEM host is specically controlling RTS. Leaving RTS
high for too long with RTS Enable set can cause data loss once the transceivers transmit queue lls.
* 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 difcult to implement without the use of CTS.

CL2510
RF Transceiver
The CL2510 utilizes a Server-Client conguration to synchronize the frequency hopping of all devices in the
network. The Server transmits a brief beacon immediately after hopping to a new frequency. This beacon
contains information about the network and the hopping pattern. Client radios will synchronize to this beacon
to ensure they are on the same frequency at the same time as the Server. The Client Link LED will light when
the Client is synchronized to the Server.
Each network should consist of only one Server and there should never be two Servers on the same RF
Channel and System ID in the same coverage area. Collocated Servers are permitted, provided the Servers
are on different RF Channels. Additional Servers in the same coverage area will degrade the performance for
all radios. Interference will increase a maximum of 2.3% for each Server added when hopping over 43 hops
and a maximum of 1.2% when hopping over 79 hops. Degradation may be transparent to the end user
depending on the number of retries/attempts and the data rate.
mODES OF OPERATION
The CL2510 has two primary modes of operation:
Transparent Mode
Command Mode
Transmit mode is used to transmit serial data across the RF and Command Mode is used to recongure
the CL2510.
TRANSmIT mODE
All packets sent over the RF are either Broadcast or Addressed (Unicast) packets.
BROADCAST PACKETS
A Broadcast Packet is one that can be received by all eligible receivers on the network. To increase the
reliability of the delivery of Broadcast packets, the transmitting radio will transmit the message the number
of times specied by the Broadcast Attempts. Broadcast Attempts are necessary because Broadcast packets
are not acknowledged by the receiving radio. Therefore, the transmitting radio has no method for guaranteeing
receipt of the message. The default Broadcast Attempts is 3 and more or less may be necessary in different
applications. Increasing Broadcast Attempts will increase the reliability of data at the cost of the overall
throughput potential of the link. The receiving radio will not forward duplicate Broadcast packets on to the
OEM host.
ADDRESSED PACKETS
An Addressed Packet is one that is only sent to a specic transceiver based upon the MAC address of the
destination. Addressed packets are acknowledged by the receiving radio, so additional Transmit Retries will
only be used if necessary. The transmitting radio will retry sending an Addressed Packet until all of the
Transmit Retries have been used or until it receives a successful acknowledgement from the receiving radio.
COmmAND mODE
Command Mode is used to congure the transceiver. To enter Command Mode on the CL2510 the OEM host
must send the AT Enter Command string “AT+++”. Once in Command Mode, all data received by the radio
over the serial interface is interpreted as command data. Data received over the RF interface will be stored in
the TX buffer until Command Mode is exited.
When using the Laird Technologies Conguration Utility, the OEM doesn’t need to worry about entering and
exiting Command Mode, as the software will do that automatically. These details on Command Mode are pro-
vided for OEMs manually conguring the radio.
* Design Tip: Entering Command Mode.
A properly formed Enter AT Command string must be issued when the RX Serial buffer on the radio is empty.
If data is either pre-pended or added to the AT string, the radio will not properly identify it as the AT Enter
Command Mode command and will not enter Command Mode. It is suggested that the OEM host wait a
sufcient period of time between the last data packet and the AT Enter Command Mode. This time varies
depending on the amount of data being sent and the number of retries/attempts congured. Waiting at
least 250ms should be sufcient for most applications.

NETWORK TOPOLOgIES
Topology refers to the shape of a network or the network’s layout. How different nodes communicate with each other is
determined by the network topology. The CL2510s support a point-to-point and a point-to-multipoint network topology.
The CL2510s do not support multi-hop meshing or any repeater functionality by default.
POINT-TO-POINT
referred to as a wireless bridge, a point-to-point link replaces a single communications cable. It does not matter which node is
the Server and which node is the Client as both nodes will support bidirectional serial data in the same manner.
POINT-TO-mULTIPOINT
Point-to-multipoint systems have one base station, or access point, that controls all communications with all of the other
wireless nodes in the network. This allows for the creation of a wireless network consisting of multiple nodes. In a
Broadcast Packets. The other nodes would be set up as Clients and set up in Addressed Mode (most likely using Auto Destination).
Data received on the Server’s serial interface would be transmitted to all Clients in range. Data received on the Client’s serial
point-to-multipoint network, but all radios would share the same bandwidth over the RF, so as more nodes were added care
should be taken when transmitting data to prevent collisions.

CL2510
RF Transceiver
In this example, client radios (because of Auto Destination and Auto Channel) will be able to synchronize
with either Server radio. Message communication from the central server will be broadcast out to all clients,
including those connected to the repeater server. Messages from the clients will be sent back addressed to
the central server.
Limitations:
There are some limitations to this setup.
• The addition of the repeaters requires two additional radios which increases the cost of the systems.
• The repeater setup of a client and server must be powered sufciently.
• The antennas of the client and the server in the repeater should be positioned to minimize interference.
For best performance the antennas should be placed more than 10ft from each other.
• There is no way to know if a client is attached to the central server or the repeater server without some
additional AT commands, this makes it difcult to perform addressed mode from the central server.
• There is no way to tell from the RF packet the clients MAC address when a message is received at the
central server, this is because all messages through the repeater will have the repeater client’s MAC address.
• The OEM must add their own layer of addressing into the data stream to address packets.
• There is some additional latency associated with the repeater; this latency is between 20 and 40ms typically.

OTHER NETWORK TOPOLOgIES
Repeater networks
Though there is no functionality for a node to automatically forward a message along to another radio,
repeater networks can be setup through the addition of a second Server to provide for additional coverage.
This example of a repeater network would still be useful for a point-to-multipoint network where some of the
nodes are not in range of the primary access point.
In this network topology a CL2510 is setup as a Server to act as the primary access point. All other radios are
congured as clients with auto-channel and auto-destination congured. Each client in range will then receive
every message from the server radio and will respond back with an addressed message to the server. To cover
additional areas, a repeater consisting of two CL2510s connected via a Null Modem cable can be added to
the network. The repeater would consist of one radio set up as a client to the central computer server and
congured identical to the other clients and one radio congured as a server in broadcast mode. Each repeater
server should be on its own RF Channel. Any client radios in range of this new repeater will synchronize to it.
All radios in the network should share the same System ID.

CL2510
RF Transceiver
The CL2510 has an internal 256 Byte EEPROM which stores system conguration information. This EEPROM
is loaded at startup and contains the networking and addressing information. The EEPROM can be congured
with AT commands manually or through the Laird Technologies Windows Conguration Utility GUI.
Basic Settings include:
mODE: SERVER/CLIENT
Designate the CL2510 network functionality. In each network, there must be only one Server, all other
CL2510s should be programmed as Clients. The number of Clients is not limited, though they all share
the same bandwidth so available throughput must be considered.
mAx POWER
The maximum transmit power of the CL2510. Reducing the transmit power will reduce the amount of
power the radio needs to transmit (current consumption). Reducing the Max Power will also allow radios
to communicate at very short ranges more effectively. At Full Power the radios should be at least 10ft away
from each other to avoid saturation.
TABLE 4:
POWER SETTING CL2510-050 OUTPUT POWER (mW) TYPICAL CL2510-100 OUTPUT POWER (mW) TYPICAL
Full Power 50 mW 125 mW
Half Power 25 mW 50 mW
Quarter Power 12.5 mW 25 mW
Low Power 10 mW 10 mW
*Power levels are approximate and can vary by 20%
RF CHANNEL
The RF Channel is a number that designates the frequency hopping pattern of the CL2510. All CL2510’s hop
over the same frequency range; the RF Channel dictates the order the radios hop through different frequencies.
All radios on the network must have the same RF Channel, unless Auto Channel is enabled on the Clients.
Collocated networks should use different RF Channels to avoid interference.
SYSTEm ID
A number that designates the network identier. All radios must be on the same System ID unless the Clients
are congured with Auto System ID.
INTERFACE BAUD
This denes the baud rate used for communicating with the CL2510 over the serial interface. The RF Baud is
independent of the Interface Baud Rate. The Default baud rate is 115,200 bps. The Interface Baud rate on the
CL2510 must match the host device baud rate.
TRANSmIT RETRIES
This value represents the maximum number of times a packet will be attempted without a successful
acknowledgement. This number is only used for packets sent in Addressed mode. The default value is 3.
Incrementing this value may increase the reliability of a link.
BROADCAST ATTEmPTS
This value represents the number of times a packet will be sent when using Broadcast Packets.
Unlike Transmit Retries, all Broadcast Attempts will be used every time a packet is sent. The default value is 3.
Increasing this value may increase the reliability of a link.
FULL DUPLEx
The CL2510 reserves two data slots per frequency hop for data transmissions. When Full Duplex is enabled,
Servers will only transmit on the rst data slot, thus reserving the second data slot for Clients to transmit.
In networks with a large amount of bidirectional data, Full Duplex will reduce collisions and reduce the need
for additional retries. Full Duplex must be set the same on all radios in the network. Full Duplex only affects the
RF transmission and not to the serial interface.

AUTO DESTINATION
Clients can enable Auto Destination to automatically set them in Addressed mode and address themselves
to the Server. This allows the OEM to program all the Clients with an identical conguration, allowing
communication with a central Server. This is valid for both point-to-point and point-to-multipoint networks.
BROADCAST
Enabling Broadcast will set the transceiver to transmit all information as Broadcast Packets.
DESTINATION ADDRESS
When not using Auto Destination or Broadcast, the OEM needs to congure the specic destination address for
addressed packets. This Destination Address is the MAC address of the intended receiving radio.
mAC ADDRESS
The MAC Address is unique 6 byte address assigned at the factory. It is the address a remote radio should place
in the Destination Address eld to communicate with that radio.
REmOTE I/O
Remote I/O for CTS/RTS and Remote I/O for DSR/DTR allow these pairs of I/O lines to have their states transmit-
ted across the RF and reected on the remote radio. These pairs of I/O lines can then be used to transmit state
information or for additional handshaking information. The I/O states are only transmitted a maximum of once
every 13ms, so these lines cannot be used for serial data.
ADDITIONAL FEATURES
The CL2510 is based on Laird Technologies LT2510 Embedded transceiver. Additional features are available
on the CL2510 including advanced API modes and additional AT Commands. For more information on these

those changes to the radio EEPROM.
Port 1/Port 2 Buttons
When the Port 1 button is depressed, the Write Radio and Read Radio buttons communicate through Port 1.
When the Port 2 button is depressed, the Write Radio and Read Radio buttons communicate through Port 2.
Calc Baud Button
The Baud pull-down menu includes all standard PC baud rates. In some rare cases, a user may want to use a
non-standard baud rate. To do this, the user will need to click on the Calc Baud button. The Calculate Baud
Rate dialog box will appear.
To calculate the settings for a particular baud rate, type that baud rate into the Desired Baud Rate text eld.
If the number in the Desired Baud Rate text eld is ±3% of an acceptable baud rate, the rest of the elds in
the Calculate Baud Rate will automatically populate. If the baud rate is not supported by the radio, the
remaining text elds will continue to display the number 0.

An example of an acceptable non-standard baud rate being accepted is shown in the following graphic:
Acceptable Baud Rate Found
No Acceptable Baud Rate Found
Clicking the Save button will cause the baud rate shown in the Actual Baud Rate window to be displayed in the
Baud window on the Congure tab of the application. Clicking Cancel will ignore these changes. The Actual
Baud Rate will not always match the Desired Baud Rate. However, the program veries that the Desired Baud
Rate is within 3% of the Actual Baud Rate (as required by the radio).
Hex/Decimal Button
All of the text entry type boxes found on the Congure tab have an indication of whether the value is
presented in Hexadecimal (Hex) or Decimal (Dec). The indication (Hex or Dec) can be clicked to toggle
between Hexadecimal and Decimal notation.
GUI View Button
Clicking the GUI View Button enables a GUI representation of the 256 byte EEPROM contents of the radio.

EEPROM Editor View Button
Clicking the EEPROM Editor View enables a hexadecimal dump of the full 256 byte EEPROM resident on
the radio. The EEPROM Editor View is shown in the following graphic, as it will appear after a radio has been
successfully read:
Load File Button
This button is used to load a le previously created by this application and can be loaded to restore an EEPROM
to a former state.
Save to File Button
This button is used to save an EEPROM program to a le. This allows for the current state of the EEPROM to be
restored at a later time.
Compare EE Button
The Compare EE button allows you to compare two or more saved EEPROM les. This can be a very useful tool
when analyzing performance of two or more transceivers. An example is shown in the following graphic:

RANgE TEST TAB
The Range Test tab allows packets of data to be sent between two radios and reports the numbers of successes
and errors. An example is shown in the following graphic:
Test Selection
There are six test options that can be selected. For each of these options, excluding Port 1 Send Only, the DVK
application will perform data verication as part of the test. This means that the application will send specic
data out and the application expects a specic response to that transmission. If it does not get that specic
response, it will report an error.
Important: The ports referred to are Ports for the application, NOT the Windows communication ports.
The available selections are:
• Port 1 -> Port 2 – This test selection is used when two CL2510s are connected to one PC.
This selection is used to send data from the radio connected to Port 1 to the radio connected to Port 2.
• Port 2 -> Port 1 – This test selection is used when two CL2510s are connected to one PC.
This selection is used to send data from the radio connected to Port 2 to the radio connected to Port 1.
• Port 1 <-> Port 2 – This test selection is used when two CL2510s are connected to one PC.
This selection is used to send bidirectional data from both radios connected to the PC.
• Port 1 Send Only – This test selection is used when one CL2510 is connected to a PC. This selection
is used only to send data from the radio connected to Port 1. This would most often be used when
the remote radio is connected to a second PC and is running the Port 1 Receive Only test. There is
no data verication with this option.
• Port 1 Receive Only – This test selection is used when two PCs are being used with two CL2510s.
One CL2510 is connected to each PC. When this selection is made, the radio attached to the port
of PC 1 will be receiving data sent from the radio attached to PC 2, which is set to Port 1 Send Only.
Both PCs should be set up with the same number of bytes in the Create Data eld. Important: The test
on both computers should be initiated at the same time. If this is not done, there may be some errors
reported until the two radios synchronize with each other.
• Port 1 Loopback – This test selection is used with two CL2510s and one PC. The PC will be connected
to one CL2510 and will be running the development software. The second CL2510 will be powered on.
The second CL2510 is set up in loopback mode, using a jumper to connect TX and RX. The radio
attached to PC 1 will transmit data to the remote radio. The remote radio will receive the data and
retransmit it back to the radio attached to PC 1.
