RS-232 WIRELESS BRIDGE USER’S MANAUL REV. 02 3

Overview

The RS-232 wireless bridge is designed to be a transparent bidirectional three-wire RS-232 cable

replacement. The RS-232 Wireless Bridge has a DB9 DCE female connector for data and for the internal

radio module configuration, and a micro USB port to configure settings that are specific to the RS-232

Wireless Bridge. The RS-232 Wireless Bridge is available in three different options differing by frequency

and RF power output.

It is possible to mix and match Wireless Bridge products. The RS-232 Wireless Bridge will communicate

with the RS- 85, Analog and Digital I/O and USB Wireless Bridge products that share the same radio

configuration. By using an RS- 85 Wireless Bridge at point A and a RS-232 Wireless Bridge at point B, the

wireless bridges can act as a RS- 85 to RS-232 over-the-air converter.

The mechanical dimensions for the Wireless Bridge are shown in Figure 1. The mechanical dimensions

are shown with the optional DIN rail mount bracket which is not included with the standard part

number. Mechanical data for the antenna is not shown.

Pinout and Wiring

The pinout follows the standard RS-232 Data Communications Equipment (DCE) device. Signal names

for RS-232 are defined from the standpoint of a Data Terminal Equipment (DTE) device. The signal

named Receive Data is an output from the RS-232 Wireless Bridge and the signal named Transmit Data is

an input. Not all RS-232 signals are implemented on the Wireless Bridge. Only Transmit Data, Received

Data and Ground are required for basic function. The DTR input may be used to control the pin sleep

function on the internal radio for reduced power draw.

Operation

Standard Operation

The RS-232 Wireless Bridge is designed to be data transparent. By default, any data sent into one device

is broadcast and received by all other Wireless Bridge devices within range. Any device that receives the

transmitted data packet will send the received data out the serial port to its host. Without any

configuration the Wireless Bridge will operate in a point-to-point or point-to-multipoint mode.

Additional addressing can be used to isolate communication between specific devices or to create

unique networks.

The Wireless Bridge device is equipped with a micro USB connector. When the micro USB connector is

plugged into a USB host device such as a computer, the Wireless Bridge enumerates 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 information port. When the micro USB connector is plugged into the RS-232 Wireless Bridge,

the DB9 port is disabled. The DB9 port is the default data port and is automatically used whenever the

USB cable is not plugged in.

The Wireless Bridge uses standard composite device drivers which are preinstalled in Windows 10 and

MAC computers. Drivers will need to be installed for Windows 7 machines. While not every machine will

enumerate exactly the same, as a general rule the lower numbered COM port is for Wireless Bridge

configuration. The higher numbered COM port can be used to transmit or receive data over the USB

port.

LED ndication

The wireless bridge has four LEDS for indication. The Blue Power LED is lit any time the Wireless Bridge is

properly powered. A green TX LED and yellow RX LEDs indicate activity on the serial port of the device.

They do not necessarily reflect all activity that may 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.

RS-232 WIRELESS BRIDGE USER’S MANAUL REV. 02 7

Data Formats and Baud Rates

The default baud rate and data format is 9600 baud, 8 data bits, no parity and one stop bit. The baud

rate and data format can be adjusted by adjusting the BD and NB parameter of the radio module (See

the Changing the Baud Rate section). 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 appear garbled.

Common Configurations and Use Cases

Radio Architectures

Point-to Point

Fig. 4 Typica RS-232 Point-to-Point Configuration

The most basic architecture is point-to-point. In this mode, one Wireless Bridge Device communicates

with a second Wireless Bridge Device. If more than one pair of radios are within range of each other,

then certain addressing commands should be set within the on board Digi XBee radio to isolate the

individual pairs. The commands that control addressing are:

ID – Controls the network identification number.

CH- Controls the channel (frequency) of the device.

DH & DL – Sets the destination address. For point-to-point mode DH & DL on Radio A should be set to

the SH & SL values of Radio B and vice versa.

See the XBee S2C manual and X-CTU program for complete details.

Point-to-Multipoint

Fig. 5 Point-to-Mu tipoint Configuration

Figure 5 shows a typical point-to-multipoint configuration. By default, all the Wireless Bridge devices will

broadcast their data meaning that point-to-multipoint mode will work without any configuration. If

there is the potential for other Wireless Bridge networks to be in the same area, then all devices in a

given network may want to be set to a non-default PAN ID.

Communicating with the Wireless Bridge

The Wireless Bridge device can be connected to a PC through the micro USB port. Figure 6 shows the

device manager view of an example connected device. Note that a single device shows up as two

separate COM ports. In Figure 6, the COM ports are COM 3 & COM . The COM port numbers will vary

from machine to machine depending on what COM port device drivers have been previously installed.

Fig. 6 Examp e COM port Device Manager View

COM ports can be opened with any terminal program. Putty, Tera term and X-CTU may all be used to

send data and communicate with the Wireless Bridge. Links to some terminal programs can be found on

the Datawave website.

Once a COM port has been opened, pressing the ENTER key can determine which port is the data

terminal and which port is the i formatio terminal. If a command prompt appears, that port is the

i formatio terminal. The command prompt for the RS-232 Wireless Bridge indicates the Wireless

Bridge type and appears similar to the text below.

RS232>

Typing ‘help’ at the command prompt will display the list of available commands as shown in Figure 7.

Any data typed into the data terminal window will result in the data being transmitted. This can be

confirmed by watching the TX LED blink when data is sent.
