Overview
The ADIO Wireless Bridge is configurable Analog or Digital input and output wireless trans ission
device. It is designed easure and replicate Analog or Digital I/O signals and wirelessly trans it those
signals to a second ADIO Wireless Bridge device. Alternatively, it can be used in conjunction with the RS-
232, RS-485 or USB Wireless Bridges to easure and trans it data back to a serial host device. In this
ode it can act as a ediu to be a wireless data logger.
The ADIO Wireless Bridge has a five pin screw ter inal block for the four channels and a icro USB port
for radio and device configuration specific to the ADIO Wireless Bridge. Data is also available on the
icro USB port. By default, the ADIO Wireless Bridge is configured to easure up to four 0-10V Analog
inputs. Inputs can also be configured for Digital inputs (3.3V and 5V tolerant) or for 4-20 A inputs. The
four channels can also be configured as 0-10V Analog outputs or as Digital signal outputs.

Operation
Standard Operation
The ADIO Wireless Bridge is intended to easure Analog or Digital Input data lines and wirelessly
trans it those signal levels to a second ADIO Wireless Bridge to output the easured signal levels. By
default, any data sent into one device is broadcast and received by all other Wireless Bridge devices
within range. The ADIO uses channel tokens to control which devices respond to the data. Additional
addressing can be used to isolate co unication between specific devices or to create unique
networks.
The Wireless Bridge device is equipped with a icro USB connector. When the icro USB connector is
plugged into a USB host device such as a co puter, the Wireless Bridge enu erates as two standard
serial COM ports. One port is a data port and can send and receive data. The second COM port is the
device’s infor ation port.
The Wireless Bridge uses standard co posite device drivers are preinstalled in Windows 10 and MAC
co puters. Drivers will need to be installed for Windows 7 achines. While not every achine will

ADIO WIRELESS BRIDGE USER’S MANAUL REV. 02 7
enu erate exactly the sa e, as a general rule the lower nu bered COM port is for Wireless Bridge
configuration. The higher nu bered COM port can be used to trans it or receive data over the USB
port.
ED Indication
The wireless bridge has four LEDS for indication. The Blue Power LED is lit any ti e the Wireless Bridge is
properly powered. A green TX LED and a yellow RX LEDs indicate activity on the serial port of the device.
They do not necessarily reflect all activity that ay be occurring over the air as they will only blink when
a properly addressed data packet is received. The Special function LED is lit when the USB port is in use.
Data Formats and Baud Rates
Since the ADIO Wireless Bridge only co unicates with a co puter through the icro USB COM port,
baud rate is not a para eter that needs changed for ost use cases. The default baud rate and data
for at is 9600 baud, 8 data bits, no parity and one stop bit. The baud rate and data for at can be
adjusted by adjusting the BD and NB para eter of the radio odule (See the Changing the Baud Rate
section). Baud rates can be set fro 1200 to 115200 bps. If the data of the sending or receiving devices
do not correspond with the data settings of the Wireless Bridge then the output data will be appear
garbled.

ADIO WIRELESS BRIDGE USER’S MANAUL REV. 02 8
Communicating with the Wireless Bridge
The Wireless Bridge device can be connected to a co puter through the icro USB port. Figure 4 shows
the device anager view of an exa ple connected device. Note that a single device shows up as two
separate COM ports. In Figure 6, the COM ports are COM43 & COM44. The COM port nu bers will vary
fro achine to achine depending on what COM port device drivers have been previously installed.
Fig. 4 Examp e COM port Device Manager View
COM ports can be opened with any ter inal progra . Putty, Tera ter and X-CTU ay all be used to
send data and co unicate with the Wireless Bridge. Links to so e ter inal progra s can be found on
the Datawave website.
Once a COM port has been opened, pressing the ENTER key can deter ine which port is the data
ter inal and which port is the in ormation ter inal. If a co and pro pt appears, than that port is the
in ormation ter inal. The co and pro pt for the ADIO Wireless Bridge indicates the Wireless Bridge
type and appears si ilar to the text below.
ADIO>
Typing ‘help’ at the co and pro pt will display the list of available co ands as shown in Figure 5.
Any data typed into the data ter inal window will result in the data being trans itted. This can be
confir ed by watching the TX LED blink when data is sent.

Common Configurations and Use Cases
Analog Signal Bridge
Fig. 6 Typica 4 Channe Ana og input to Ana og Output Signa Bridge
A co on configuration for the ADIO Wireless Bridge is as an Analog signal bridge. By default the ADIO
Wireless Bridge is configured to accept 0-10V analog inputs. By configuring a second Wireless Bridge for
Analog outputs the analog input voltages on the trans itting radio will appear at the outputs on the
receiving radio. Not all channels need to be the sa e type. Each channel can be configured as an analog
input, analog output, 4-20 A input, Digital input or a Digital output. For si plicity, Figure 6 shows one
radio with all Analog inputs and a second device with all Analog outputs.
Devices use channel tokens to deter ine if signals should be replicated and output. For I/O line passing
to occur, one channel ust be an input and the corresponding channel ust be set to be an output. The
channel token values ust also atch. It is possible to have a single input driving the signal outputs on
ultiple radios.
To set up the Wireless Bridge for Analog I/O line passing:
For any radio with Analog inputs:
1. Set the channel token value for each channel that will be used. This value can be different for
each channel or it can be the sa e, but a value set in channel 1 will not enable a different
channel. To set a channel token at the co and pro pt type:
ADIO> set ch.X.token YYYY where “X” is the channel nu ber 1-4 and “YYY” is any value fro 0
up to 4 illion.
2. Set the io.txrate value in illiseconds.
3. Use set store to save the configuration.

ADIO WIRELESS BRIDGE USER’S MANAUL REV. 02 11
For the radio with Analog outputs:
1. Set the channel type
2. Set the channel token value to atch the value of the input channel token.
3. Set pkts.en para eter to 1.
4. Optional: Use set store to save the configuration
Exa ple:
Figure 7 shows a setup for two radios. COM44 is the infor ation COM port of Radio A and COM57 is the
infor ation COM port of Radio B. In this exa ple, Radio A is the input radio and Radio B is the output
radio. The sa e value was used for the channel tokens on all channels in this exa ple. The channel
types on Radio B were set to analog outputs (type 2) and the pkts.en co and was set to 1.

ADIO WIRELESS BRIDGE USER’S MANAUL REV. 02 12
Digital Signal Bridge
This is si ilar to the analog signal bridge except that the outputs will transition when the inputs cross
logic voltage thresholds. The High input voltage threshold is 2.1V and the low threshold is 0.8V. By
default the high output voltage is 3.3V but this can be adjusted with the chX.lvl. dovolts co and. See
the ADIO co and reference table for details. For digital I/O line passing the following setup should
occur. Optional para eters are noted.
Input radio:
1. Set the ch.X.type to 3
2. Set the ch.X.token value
3. Optional: Set ch.chX.cd if you want the radio to trans it only on an input signal change. Also set
cd.rate if this para eter is used.
4. Set the io.txrate para eter if change detect is not used
5. Optional: Use set store to save settings to non-volatile e ory.
Output radio:
1. Set the ch.X.type to 4
2. Set the ch.X.token value
3. Set the pkts.en co and to 1.
4. Optional: set default starting voltage, ti eout and output voltage level if desired.
5. Optional: Use set store to save settings to non-volatile e ory.
Wireless Data Collector
Fig. 8 Wire ess Ana og Data Co ector
The other Datawave Wireless Bridge products can receive and process data fro the ADIO Wireless
Bridge. Figure 8 shows the typical architecture for this scenario. The ADIO Wireless Bridge can trans it
the status of the Input channels at an interval specified by the io.txrate co and. With the pkts.en
co and set to 1, the receiving radios output the data in JSON (default) or si ple text for at. Figure 9
shows an exa ple output packet. In Figure 9, the na e field is blank and all the channels of the
trans itting radio are set to analog inputs (AIN). The voltage value of each channel is shown in
illivolts.

Changing the Baud Rate
The Wireless Bridge device is ade up of two ain co ponents:
1. The host processor
2. XBee radio odule
The host processor anages the USB interface, the infor ation enu and co unication to and fro
the XBee radio odule. Changing the device’s baud rate is a two-step process. In order to change the
baud rate successfully, the following steps ust be followed in order.
1. Change the baud rate on the XBee odule through the data COM port using AT co ands or
the X-CTU progra . Write the para eter to non-volatile e ory.
2. Change the Wireless Bridge device baud rate through the information COM port using the set
uart.rate co and. Write to non-volatile e ory using the set store co and.
Exa ple:
Changing the baud rate fro the default 9600 to 115200 bps.
Step 1: Using the X-CTU progra , the XBee radio odule is discovered on the data port – in this case
COM43. The baud rate is changed to 115200. The “Write” button is used to store the setting.

Configuring the XBee Module
The ADIO wireless bridge utilizes the Digi XBee odule. Consequently, all radio settings can be read or
set with Digi AT co ands or The Digi X-CTU software. As a general rule the only co ands that ight
need be set are the Networking and Serial Interfacing co ands. Any I/O co ands or other features
are not used. See Digi’s website at www.digi.co and the XBee user anual and discussion foru s for
