APPOINMENT


Wireless communication device (later in text named as WCD)

is functionally and structurally complete
device for wireless communication

between

devices with

one of
interfaces
:

-

RS
-
232

-

RS
-
485


WCD is

used as
a wire
less alternative to wired lines and is

installed

to replace the cable
s (between

external
device
s) with

radio communication
.
WCD

is designed to transmit / receive data
via radio channel at a speed
of

up to 9600

bit / s in the frequency range (2410
-
246
5) MHz
with

the t
ransmitter output power up to 1
0

mW
.

If

cable routing between devices

(which usually are using
wired communication chan
nels

for data
exchange
)

is impossible,

then

it is necessary to look for other means of communication
,

other than wire
d
.
Wireless transmission of data between devices is one of possible solutions
for this

problem.
WCD

is a
variation of radio extenders for
communication
line
s

us
ing

for communication interface
s

RS
-
232
and

RS
-
485.


WCD

is connected to an external device

via

co
mmunication
interface RS
-
232 or RS
-
485 (2
-
wire or 4
-
wire)
and is

"transparent"

for the devices (
additional

modification of

the device is

not

required
)
.

After switching
-
on WCD itself scans the radio channel, searching for any other WCD

devices

in the networ
k
and establishes contact with them without any commands from the device, connected to WCD. Thus,
devices connected to the WCD can exchange data

over the air the same way as they did it using wired
communication.

WCD operates in a mode of direct access to
the radio channel, thus, external devices can exchange data
over the radio channel, using their own protocols, addressing, coding etc. Using the protocol of addressing
between external devices, WCD can be used to connect a group of external devices
in
to th
e
common
network.

WCD is designed for application

in different remote control systems,

data collection

system
, etc.
WCD

can
be

easily integrated into already
existing

system
s

without
redevelopment

of the software.

OPERATION MODES


Selection of WCD o
peration mode is made using jumpers located on WCD PCB board.

DATA mode

This mode is the main mode of
WCD
. In this mode data from the

external

device

connected to WCD is sent

through

radio channel

t
o

address
es
, specified in
address table of the
WCD

(see co
mmand "LIST ADDR"

in
section “
List of WCD commands

in configuration mode

)
.

To select this mode, you need to set the jumpers:

In data mode
-

«POWER» LED will be constantly

CTU mode

This mode allows using the X
-
CTU utility to configure the Zigbee
-
module within WCD.

with
two short
shinings
per second (double
shining
every second).

Read more about X
-
CTU utility for configuration of Zigbee
-
modules in section “X
-
CTU utility”
.

Co
nfiguration mode

This mode allows you to configure WCD (see "List of WCD commands

in configura
tion mode
").

To select this mode, you must remove the jumper:

Jumper
XS5
:


remove jumper

In the configuration mode
-

«POWER» LED
will blink one short
shining

every second (0.1 sec.
shining

and 1
sec. without
shining
).

To configure WCD it is necessary to co
nnect
personal

computer through the
COM
-
port (
RS
-
232
interface)

to WCD.

It is necessary to r
un any terminal program (for example

H
yper
T
erminal
)
with

the following parameters:
baud rate
= 38400, data bits = 8, stop bits = 1,
p
arity = none, flow control =
no
ne.

After connection to power supply unit

WCD
begins testing.
Upon completion of testing

terminal program
launched on the personal computer
will display a message about loading of the operating system

in WCD:

START

OF OPERATION


To turn on WCD it is necessary to connect the power supply to one of the connectors "9 ...
24V


on the
back panel of

WCD

(either using a power supply plug or wires screwed to the terminal block)
. After power

up

WCD en
ters the test mode and launches

the radio channel.
WCD activation ends with "POWER" LED
indication.


In data mode
-

«POWER»

LED will be constantly shining
.

In this mode, the modem allows externa
l devices
to exchange data via
radio channel.

In the configuration mode
-

«POWER» LED will blink one short flash every second (0.1 sec.
shining

and 1
sec. without
shining
).

In this mode
, WCD configuration can be perfo
rmed using

commands
,

described in
section “Configuration” on this Technical Guide
.

In
X
-
CTU

mode
-

«POWER»

LED will blink two short
times

per second (double
shining

every second).

This
mode allows us
age

of

X
-
CTU utility to configure the Zigbee
-
module.

lete documentation on the used
X
-
CTU utility
can be downloaded from official website:

M ports:

-

port
#
0


is

an

external COM port

of the
WCD, to which external devices are to be connected

-

port
#
1
-

is an internal COM port

to which
Zigbee
-
module

is connected

Therefore as a

<number>

parameter
it is necessary
to specify value “
0


or

1

.

This command allows to obtain
a value for
timeout

of
COM
-
port

for
waiting
o

arrival of
the next
byte in the packet
coming from external device
before
transmitting of the obtained bytes package
over the radio channel

B
efo
re
transmitting over the radio channel WCD
within
<packtimeout>

milliseconds
is waiting for

accumulation

of
data packet in its buffer
.
If
during the timeout limit no byte has arrived from
the COM
-
port


WCD transmits obtained data packet
over the radio cha
nnel. If case if some byte has
arrived until timeout is expired


byte is added
to the data packet and again process waits

until
timeout expiration.


SET PACKTIMEOUT


SET PACKTIMEOUT,

<

This command allows to set
a value for
timeout

for COM
-
port for

waiting
of

EXAMPLE OF APPLICATION ON PETROL STATION


Following picture shows a configuration of petrol station, where wired connections to fuel dispensers and
ATG system is made wireless instead of wired.

In order to provide control over fuel dispensers each of the fuel dispensers should be connected to WCD

(several fuel dispensers or all of them can be connected to the same WCD).

In order to provide control over ATG systems ATG console (or ATG probes directly) should be connected to
WCD.
