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 classified 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 flow 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 flow 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 specifically controlling RTS. Leaving RTS high for too long with RTS Enable set can cause data loss once the transceivers transmit queue fills.

* 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.

CL2510

RF Transceiver

THEORY OF

OPERATION

The CL2510 utilizes a Server-Client configuration 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 reconfigure 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 specified 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 specific 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 configure 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 Configuration 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 provided for OEMs manually configuring 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 sufficient 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 configured. Waiting at least 250ms should be sufficient for most applications.

THEORY OF

OPERATION

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

a point-to-point network consists of only two radios, one configured as a Server and one configured as a Client. Sometimes 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.

OEM

Host

OEM

Host

Server Client

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 point-to-multipoint network the Server would typically be set up as the access point and would be configured to transmit

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 interface would be transmitted only back to the Server. There is no limit to the number of Clients that can be configured in a 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.

OPERATION

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 configured as clients with auto-channel and auto-destination configured. 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 configured identical to the other clients and one radio configured 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.

8 www.lairdtech.com

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 sufficiently.

• 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 difficult 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.

SETTINgS

The CL2510 has an internal 256 Byte EEPROM which stores system configuration information. This EEPROM is loaded at startup and contains the networking and addressing information. The EEPROM can be configured with AT commands manually or through the Laird Technologies Windows Configuration 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.

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 identifier. All radios must be on the same System ID unless the Clients are configured with Auto System ID.

INTERFACE BAUD

This defines 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 first 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.

CONFIgURATION

SETTINgS

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 configuration, 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 configure the specific 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 field 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 transmitted across the RF and reflected 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 features refer to the LT2510 User Manual.

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:

17 www.lairdtech.com

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 verification as part of the test. This means that the application will send specific data out and the application expects a specific response to that transmission. If it does not get that specific 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 verification 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 field. 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.

OVERVIEW

There are three typical hardware setups.

1. One radio is plugged into a serial or USB port on a PC. The second radio is plugged into a separate

power supply with a loopback adapter connected.

2. One radio is plugged into a serial or USB port on a PC. The other radio is plugged into a different

serial or USB port on the same computer.

3. One radio is plugged into a serial or USB port on a PC. The other radio is connected to a serial or

USB port on another PC.

If using two PCs for the test, the application run on both sides should have the second COM port disabled on the PC Settings tab.

Problem read radio or Write radio displays error message:

“radio not responding.” solution

1. verify that power is applied and that the serial/USB cable is connected to the serial

board and the PC.

2. verify that the correct serial/USB port is selected in the software (Port 1 or Port 2).

3. verify baud rate and port address on the PC Settings page.

4. verify the Port Status is open in the Status bar or in the Port 1.

5. shut down the software and restart it.

6. reset the radio by cycling power after each unsuccessful read.

1. verify that baud rate and parity settings are correct.

Garbled Data received.

Client’s Link LED does not come on.

1. Make sure server CL2510 unit is connected to power.

2. Cycle power to the radio.

3. verify rF Channel and System ID are set correctly.

Link LED is on, but data does not get transmitted or received.

1. Make sure the CL2510 unit(s) is connected to the correct COM Port.

2. Check the COM port settings for correct Baud rate, Parity and either Hardware or

no Flow Control. Units can have transmission errors with Flow Control set to Xon/Xoff.

3. Try increasing the max Transmit retries (for Clients) and/or Broadcast attempts

(for servers) values in small increments until communication is established.

4. Check the Destination Address setting.

5. verify the radios are at least 10ft apart.

CL2510 BASICS AND TIPS

1. There needs to be one and only one Server per network (RF Channel Number & System ID);

there can be any number of Clients.

2. The Default configuration is a Client radio with the addressing mode not set. For the radios to

communicate the addressing must be set to either:

• Broadcast Mode

• Auto Destination (for Clients only)

• The MAC Address of the remote radio must be entered into the Destination Field.

3. The Link LED on the Server will always be lit. The Link LED on a Client will only be lit when it is in sync

with a Server. The Link light must be lit for RF communications to occur.

4. Configuration should always be performed with the Laird Technologies Windows OEM Configuration Utility.

Though the radios are serial modems accessible through traditional terminal emulators, such as

HyperTerminal, the AT commands must be sent in their entirety, which cannot be achieved when typed in.

Once configured testing can be performed with HyperTerminal or another emulator to send serial data.

5. Windows only allows one program to access a Serial Communications Port at a time. Therefore when the

Laird Technologies Windows OEM Configuration Utility is open, no other serial applications should be open.

6. When using the USB Evaluation Board, it is recommended to Close the Port on the PC Settings tab prior to

unplugging the USB cable or powering off the module. If not, the port may become unavailable and need

to be either toggled by Closing and Opening the Port or the software may need to be reset.

7. The PC Settings tab is used to set the configuration of the OEM Configuration Utility, not the radio.

The Configuration Tab is used to configure the radio, but the radio’s EEPROM must be read first.
