Quick Start
2.1 Board Description
The Trane RF module is a 2.4GHz 802.15.4 data transceiver module based
on the Freescale MC13192 Low Power Transceiver device. It provides
enhanced range performance with a 100mW* power amplifier. The module
also contains the Freescale MC9S08GT60CFD microprocessor and an
integrated PCB trace antenna. Power is supplied by the host device through
the interface connection in accordance to the operating voltage requirements
with a nominal operating voltage of +3.3V. Exact details on the interface
connections and messaging are available upon request.

* Operation is Limited to 10mW Maximum for European Union Compliance
Page 5 of 41
2.2 Operational Overview
The quick start demonstration presented in this chapter is referred to as the
ping pong test*. The ping pong test allows an end user to easily verify
communication between two transceivers and get a feel for the quality of the
link via feedback of the flashing LEDs.
Operation involves two boards, with one designated as a master device and
the other as a slave device. The master periodically transmits packets to the
slave. If the slave receives and verifies the packet, it will flash its LEDs and
transmit an acknowledgement to the master. If the master receives and
verifies the acknowledgement, it will flash its LEDs.
In normal ping pong mode, LEDs indicate signal strength (two LEDs on
indicate high signal strength, one LED indicates low signal strength). If the
LEDs do not light, the packet or acknowledgement was not received.
2.2.1 Power Up
Insert batteries into interface boards and verify that battery supply is selected
using the jumper as shown in Figure 3-2 chapter 3.
2.2.2 Master/Slave Selection
Master device setup:
1. Press white reset button on Interface Board (See Figure 3-1 location
3) and black button on Trane RF module simultaneously.
2. Release reset button on Interface Module.
3. Wait until green LED is lit, then release button on Trane RF module
Slave device setup:
1. Press white reset button on Interface Board (See Figure 3-1 location
3) and black button on Trane RF module simultaneously.
2. Release reset button on Interface Module
3. Quickly release the button on Trane RF module (Release within 1.5
seconds of performing step 2 above).
2.2.3 Association Mode
In association mode, the red LED will flash rapidly on each board until it has
linked with the other device. At this point, the red LED will go out and the
green LED will begin to flash rapidly for approximately two seconds.
Association mode lasts up to thirty seconds after power up, so the master
and slave pair should be powered up at relatively the same time. If the
transceivers link, they will enter the ping pong mode after association mode
times out. However, if they do not link, they will not communicate and the
sequence must be repeated from the point of master/slave selection at
power up.
* Demonstration Application Operates at 100mW (This value is Not European Union Compliance)
Page 6 of 41
2.2.4 Ping Pong Mode
In ping pong mode, the master and slave boards will flash one or two LEDs
with each packet (slave) or acknowledge (master) received, based on
message signal strength. In case there is a lot of other traffic on the default
channel, it is possible to change the channel.
2.2.5 Channel Changing (can only be peformed if boards have been
associated)
While in the ping pong mode, the current channel can be changed to one of
four other unique channels (five channels total). This is accomplished by
holding the push button for approximately two seconds, at which point the
green LED will be lit steady. Once the push button is released, the current
channel option number (one through five) is displayed by a series of flashes
on the red LED. Each short push button press will increment the channel
option number and display it with a given number of flashes on the red LED.
To accept the last selected channel, hold the push button until the green LED
goes out (approximately two seconds). After again releasing the button, the
device will return to the ping pong mode.
Note that both the master and slave devices must be set to the same
channel option number for the pair to communicate, and each board must be
individually set to that given channel option number.

4.3 Setting Up and testing a Wireless Link
Operational testing of the Trane RF module requires at least 2 units in order
to establish a link. One unit will be the initiator and the other will be the
responder. In order for a link to be established it is necessary to setup the
transceivers RF Channel, long or short address and PAN id.
Link testing may be performed in either a single ended or a round trip
fashion. This can help to differentiate between real world packet error
performance and raw radio performance. If Acknowledgement settings are
not used then it is a single-ended test, if Acknowledgements are enabled
then it is a round trip test.
4.3.1 Single-ended Test
Single ended performance will require 2 computers, since it will be necessary
to read the statistics from each radio. An example setup is outlined below.
Device 1 (Refer to Figures 4-7 and 4-9)
1. Set PAN ID to 100 (IDs Page)
2. Set Short Address to 1 (IDs Page)
*Note to use long addressing set short address
to 65,534
3. Disable Acknowledgements/Retries (RF Settings Page)
4. Disable Receive All RF Messages (RF Settings Page)
5. Set to RF Channel 23 (RF Settings Page)
6. Set transmitter power setting to 31 (RF Settings Page)*
7. Set Short Destination address to 2 (Located Upper left corner of TT)
8. Select Short Address Radio Button (Upper Section of TT)
*Long may be selected if sending to a long address device
9. Select “Save Config To NV Memory” Command Button (Upper
Section of TT)
10. Check the Show Received box (Upper Section of Test Tool)
*Set to a value of 14 to operate at 10mW Maximum for European Union Compliance.
Page 19 of 41
Device 2 (Refer to Figures 4-8 and 4-9)
1. Set PAN ID to 100 (IDs Page)
2. Set short address to 2 (IDs Page)
*Note to use long addressing set short
address to 65,534
3. Disable Acknowledgements/Retries (RF Settings Page)
4. Disable Receive All RF Messages (RF Settings Page)
5. Set to RF Channel 23 (RF Settings Page)
6. Set transmitter power setting to 31 (RF Settings Page)*
7. Set Short Destination address to 1 (Located Upper left corner of TT)
8. Select Short Address Radio Button (Upper Section of TT)
*Long may be selected if sending to a long address device
9. Select “Save Config To NV Memory” Command Button (Upper
Section of TT)
10. Check the Show Received box (Upper Section of Test Tool)
Figure 4-7 ID Settings for Device 1

Place the 2 units in physically separate locations and apply power to them.
The statistics will clear when power is cycled, but they will need to be cleared
manually after each test if power is not cycled.
Connect each individual PC serial port to each of the units and verify the
correct destination address is typed in the address field on the top of the test
tool. Type a short message into the “RF Data” window of the initiating
device. The message can be any text or numbers. If no message is entered
it will not be possible to transmit.
Set the “Repeat Delay” to 100 msec if it isn’t already set. Click the “Send
Single Repeated Msg” button to start transmission. The radio will send
messages repeatedly with 100mSec in between messages until the “Stop
Repeat” button is clicked.
Allow the test to run for some convenient amount of time and then stop
transmission. Go to the “Statistics” screen of the initiating device and select
the “Query Statistics” command button and record the packets sent in the
Transceiver section of the test tool. Next select “Query Statistics” on the
receive device and record packets received in the Transceiver section of the
Statistics page. Link success is simply the ratio of the “Packets Received” to
the “Packets Sent”.
This test will give the raw performance of the link in one direction without
retries. It is a good indicator of the RF environment in which the radios are
being used. High levels of noise or other products operating in the 2.4 GHz
band can cause lower packet success rates.
4.3.2 Round Trip Test
To test the ability of the system to retry messages in a noisy environment, it
is necessary to use a round trip test where the remote end can acknowledge
receipt of packets. Use the setup screen as shown in Figure 4-7 thru 4-9 for
each respective device, but enable acknowledgements on both devices
(Refer to RF Settings Page).
Perform the test in the same manner as the single ended test. Run enough
transmissions to get a statistically valid sampling of the radio environment
over a reasonable period of time.
Look at the “Statistics” screen on the initiating radio to find the total number
of packets sent. Link quality is displayed in the Pkt Success Rate w/Acks
text box. Total link success is the ratio of “Acks Received” to “Packets
Sent”.

Trane RF Module Input/Output
5.1 Overview
There are a total of 10 user input/output pins on the Trane RF module which
consist of 8 configurable digital input/outputs and 2 fixed analog inputs.
5.2 Digital Inputs/Outputs
There are 8 configurable digital input/output pins that can be programmed to
be either inputs or outputs. In addition if the pins are inputs the internal
pullup resistor can either be enabled or disabled. Refer to Table 1 below for
a mapping of the digital input and output pins.

Using the digital input output pins consists of the following:
•
Configuring the pins
Select direction (input or output), enabling or disabling pullup
resistors for pins configured as digital inputs, and setting the
initial output value for pins configured as digital outputs. These
parameters define the configuration of the pins when a reset
occurs. Also the direction and pullup parameters are used to set
the state of the pins after exiting sleep mode.
•
Configuring the sleep state of the pins
Select direction (input or output), enabling or disabling pullup
resistors for pins configured as digital inputs, and setting the
output value for pins configured as digital outputs. Although
these parameters are the same as those shown in the
“Configuring the pins” item shown above, they are independent
and are the state of the pins when the Trane RF module is put
into Sleep Mode.
•
Reading the state of the pins configured as inputs
Read the digital value (0 or 1) of the signal applied to the pins
configured as inputs.
•
Setting the state of the pins configured as outputs
Set the digital value (0 or 1) for the pins configured as outputs.

CHAPTER 6
Trane RF Application Guide
6.1 Overview
This Chapter describes the essentials for using the host protocol to configure
and use a Trane RF module in an application. Please refer to Host Protocol
Document for Further Details on messaging.
6.1.1 Host Protocol
The host protocol that is used to communicate with a Trane RF module is a
simple binary based protocol. Every message in the protocol consists of a
header, a trailer, and potentially some payload information.
The header is made up of a start byte (0x01), a length byte that is the length
of the entire message including header and trailer, and a message type that
identifies the intention of the message.
The payload varies from message to message but in general includes things
such as data to be sent or received, or configuration information.
The trailer is made up of a checksum, which the sum of all of the bytes in the
message is starting with the start byte and up through the payload, and an
end byte (0x04).
Every message that the host device sends to the Trane RF module has a
complimentary acknowledgement message that will get sent back upon
successful decoding and processing by the Trane RF module.
6.1.2 Configuration
After power-up or after receiving a “Reset Request” (type 0x18) message,
the Trane RF module will read the configurable parameters from the onboard microcontroller’s non-volatile memory, and store them in RAM to be
used from that point on. Changing a parameter by sending the module a
new message does not automatically result in the module saving the
parameter to non-volatile memory, but rather just changes the value stored in
RAM. This allows a particular host application to change the configurable
parameters dynamically without unnecessarily writing to, and shortening the
lifetime of, the non-volatile memory. All of the Trane RF module’s
configurable parameters that are stored in RAM can be saved to non-volatile
memory by sending a “Save Configuration Values to Non-Volatile Memory”
(type 0x11) message.
Page 25 of 41
Communication Parameters
There are six configuration parameters used to setup the Trane RF module
for communications, which are outline below.
1. Set PAN ID – The Personal Area Network (PAN) ID is used to
establish networks of transceivers. Only devices with the same PAN
ID will communicate with one another.
2. Set Transceiver Address – The Transceiver Address is used to
differentiate transceivers within a network. Each transceiver should
be configured with a different address. The Transceiver Address
consists of both a short two byte and a long eight byte address.
Setting the short address to 65,534 (0xFFFE) will cause the Trane
RF module to use its long address. To use the short address, the
short address should be set to between 0-65,533.
3. Set RF Channel – The RF channel is used to select the channel in
the 2.4GHz band that the transceiver will operate on.
Communication between transceivers is only possible if the devices
are both using the same RF channel. Valid RF channels are from 11
to 26.
4. Enable/Disable Receive All RF Messages – Enabling receive all RF
messages allows all messages on the configured PAN ID to be
received by the Trane RF module. This intended use of receive all
messages is for diagnostics tools so that it is possible to see all
messages on a network. Note that when this mode is enabled that it
is not possible to transmit RF messages.
5. Enable/Disable RF Acknowledgements and Retries – When RF
Acknowledgements and Retries are enabled, the destination
transceiver will respond to the received message with an
acknowledgement. If the source transceiver does not receive an
acknowledgement, it will attempt to re-send the message to the
destination transceiver up to 3 more times (3 retries). By using
acknowledgments and retries, the likelihood of successfully getting a
message from one transceiver to another increases.
Set Transmit Power Level – This setting allows for adjusting the transmit power, which affects the
overall range. The range varies from 0 to 31. (Set to 31 for 100mW operation or 14 to operate at
10mW Maximum for European Union Compliance.)
Page 26 of 41
Input/Output Parameters
There are three configuration messages used to setup parameters for
controlling the user input and output pins, which are outlined below.
1. Set Digital Pin Configuration – This message is used to configure the
direction (input or output), whether or not the internal pull-up resistor
is enabled for pins configured as inputs, and the initial output value
for pins configured as outputs. The initial output value is the default
state that output pins will be assigned after power-up or a “Reset
Request” command is issued to the module.
2. Set Digital Pin Sleep State – This message defines the state that the
digital pins will be put into when the low power sleep mode of
operation is requested for the module. Similar to the “Set Digital Pin
Configuration” message, the direction of the pin, whether or not the
pull-up resistor is enabled for input pins, and the output value for
output pins can be configured. Upon exiting sleep mode the pins will
be configured back to the state they were in prior to entering sleep
mode.
3. Set Analog Pin Sleep State – This message is used to set the state
of the two analog input pins when the transceiver is put into the low
power sleep mode of operation. It is possible to leave the pin
configured as an analog input, or change it to an output either driven
low or high. Upon exiting sleep mode the pins will be configured
back to be analog inputs.

Diagnostics and Feedback Parameters
There are two configuration parameters used to setup diagnostics and user
LED feedback which are outlined below.
1. Set Debug Mode – Setting the debug mode allows the host
application to configure what debug information gets displayed on
the three mode pins when the mode pins are in their default state.
The default state for the mode pins is that none of the external pulldowns are installed. The intent of the debug signals is to allow for
monitoring on an oscilloscope how the device is operating.
2. Set LED Functionality – This message is used to configure if any
LED feedback information is enabled or not, and if it is enabled what
it represents. For modules that are embedded in an enclosure, the
LED functionality can altogether be disabled to further reduce power
consumption. Several examples of the types of functionality that can
be displayed on the LEDs are a heartbeat LED flash to indicate the
microcontroller is running or flashes when an RF or serial message
is either transmitted or received. Multiple functions can be enabled
simultaneously.
Example configuration
The following example will show details of what host protocol messages a
host device would send to a Trane RF module to configure all of its
programmable settings. After all of the settings have been sent to the
transceiver, save configuration parameters message is issued to save the
settings to non-volatile memory.

For all of the messages shown above that would get sent from the host
application to the Trane RF module, a host level acknowledgement will be
sent back when it has been successfully processed. It is recommended that
the host application send a message to the module and then wait for an
acknowledgement response prior to sending the next message. This will
take care of flow control and prevent the host application from overflowing
the module.

6.1.3 RF Messaging
Overview
The Trane RF module provides a versatile command set for communications
between modules. Depending on the application’s requirements, either short
or long address modes can be used. Short addressing mode uses a two
byte transceiver address, while long addressing mode uses eight byte
transceiver addresses.
It is also possible to communicate between
transceivers using mixed addressing modes, hence a message can be sent
from a transceiver with a short address to another transceiver with a long
address or vice versa.
There is a single host message that is used to send data from one
transceiver to another and two host messages that are generated when a
message is received. When in the receive all mode of operation and a
message is received by a transceiver, host message type 0xA9 is generated
and sent out the serial port to the host. In the default mode of operation
(receive all mode disabled) host message type 0x95 is generated and sent
out the serial port to the host.
RF host messages consist of a standard header (start, length and type), RF
message header, payload, and a standard trailer (checksum and stop). The
RF message header contains a Packet ID, a Target/Sender identifier, an
Address Mode byte, and the Transceiver Addresses. The Packet ID is used
to identify each message and should be incremented for each new packet
when sending a message. The Target/Sender byte indicates where the
message originated from and is being sent to. Messages either are
originated from or sent to either the host or the application. The application
is the user application code that is running on the Trane RF module
(currently not supported). The host is the host application. The Address
Mode byte describes the type of addressing for the particular message. The
upper nibble indicates the addressing mode used for the destination of the
message, while the lower nibble indicates the mode for the source of the
message. A 0 is used to represent a short address, while a 1 represents a
long address. Following the Addressing Mode is the destination address and
then the source address (for received messages only – types 0x95 and
0xA9).
Short Addressing
In order to use short addressing it is required that the transceiver address be
set between 0 and 65,533 (0xFFFD). Setting the short address to 65,534
causes the transceiver module to use the eight byte long address.
Long Addressing
Long addressing mode is configured by setting the short address to 65,534
and then selecting a long address in the range of 0 to
18,446,744,073,709,551,614 (0xFFFFFFFFFFFFFFFE).
Broadcasts
It is possible to broadcast a message to all transceivers configured to the
same RF channel and PAN ID. Messages are broadcast by sending the
message to the short destination transceiver address 65,535 (0xFFFF).
Page 30 of 41
Receive All
Receive all mode is used as a diagnostic mode in which a transceiver can
listen to and receive all of the messages from any device that is
communicating on the same PAN ID and RF channel. Messages with long
and short addressing types will be received, and when a message is
received it is sent out the host serial port with a message type of 0xA9. In
receive all mode it is not possible to transmit messages to other transceivers.
Addressing Modes Summary
The table below gives an overview of the addressing modes that are
available in the Trane RF module. The table shows a summary of what
happens when messages are sent between two modules (Transceiver A and
Transceiver B) using the various addressing modes (short and long), and
also broadcasts.
The first column “Host Send Mode” lists what type of message the host
would send to the Trane RF module into transceiver A. The “Addressing
Mode” columns show what type of address (short or long) each transceiver is
configured to use. Upon transceiver A receiving the message from the host
device, transceiver A would then send a message over the RF link to
transceiver B using the type of address shown in the first column. If
transceiver B successfully receives the RF message from transceiver A, then
a host message is generated that will be sent from transceiver B to the host
connected to transceiver B. The messages that get generated will have the
source and destination addresses contained in it which are shown in the
table under the “Host Receive Mode” columns. A dash (-) denotes that a
message was not received by the transceiver because the destination
address for transceiver B was not the same type (short or long) as the
destination address type to which the message was sent (shown in the first
column). It is assumed that the destination address to whom the message is
being sent is the same as that address for which the receiving transceiver is
configured to use.

Table 2 – Addressing Overview
Note 1: Since a transceiver is setup with both a long and a short address, if long addressing is
being used (short address = 65,534) and a message is being sent to the transceiver with a short
address of 65,534, a RF acknowledgement will be sent by the MAC.
Note 2: Since a transceiver is setup with both a long and a short address, if short addressing is
being used (short address not equal to 65,534) and a message is being sent to the transceiver
with a long address that matches the transceiver’s long address, a RF acknowledgement will be
sent by the MAC.

6.1.4 Example Messaging
For all of the following examples it is assumed that the PAN ID and RF
channel are set to be the same on both Trane RF modules. Also the
messages will originate in the host connected to transceiver A and they will
be sent to transceiver B. The data contained in the message will be 0x01,
0x02, 0x03. All received messages have a Link Quality Indication (LQI) of
200 (0xC8).

6.1.5 Input/Output Usage
There are three host messages used to query and set the inputs and outputs
respectively. Below is a more detailed description of each of the messages
with examples showing the corresponding host messaging.
1. Query Analog Pin Values – This message is used to read the values
of the two analog input signals. The result is returned in a host
message that gets sent back from the Trane RF module containing a
two byte value (LSB to MSB), for each of the two analog inputs, with
the 10 least significant bits representing the voltage applied to the
inputs. The input signal voltage is converted to a 1.25v reference.
Example:
Analog Input PTB0 = 0.42v (10 bit value => 344 = 0x0158)
Analog Input PTB1 = 1.07v (10 bit value => 876 = 0x036C)
Host -> Trane RF Module – (Query Analog Pin Values – Type 0x22)
< 0x01 0x05 0x22 0x28 0x04 >
Trane RF Module -> Host – (Respond With Analog Pin Values –
Type 0xA2)
< 0x01 0x09 0xA2 0x58 0x01 0x6C 0x03 0x74 0x04>
Page 35 of 41
2. Query Digital Pin State – This message is used to read the values of
the eight potential digital input signals. A bit mask for each digital
input/output signal is returned in a host message that gets sent back
from the Trane RF module. Only digital pins configured as inputs
contain any meaningful information. A zero indicates a low signal is
applied to the input, while a one indicates a high signal is applied.
Example:
Digital Pin Configuration – Inputs = PTC1, PTC5, PTD3, and
PTD4.
Digital Input PTC1 = 0
Digital Input PTC5 = 1
Digital Input PTD3 = 0
Digital Input PTD4 = 1
Host -> Trane RF Module – (Query Digital Pin State – Type 0x21)
< 0x01 0x05 0x21 0x27 0x04 >
Trane RF Module -> Host – (Respond With Digital Pin State – Type
0xA1)
3. Set Digital Pin State – This message is used to write the values of
the eight potential digital output signals. A byte containing a bit mask
for each digital input/output signal is sent in a host message to the
Trane RF module. Only digital pins configured as outputs contain
any meaningful information. A zero indicates a low signal is applied
to the output, while a one indicates a high signal is applied.
Example:
Digital Pin Configuration – Outputs = PTA4, PTA5, PTA6,
and PTC0.
Digital Output PTA4 = 1
Digital Output PTA5 = 0
Digital Output PTA6 = 0
Digital Output PTC0 = 1
Host -> Trane RF Module – (Set Digital Pin State – Type 0x20)
< 0x01 0x06 0x20 0x24 0x4B 0x04 >
Trane RF Module -> Host – (Set Digital Pin State Acknowledged–
Type 0xA0)
< 0x01 0x05 0xA0 0xA6 0x04>
