6. Installation

6.1 Connect

Connect WCS-232 to a serial port on a PC or a
communication device and supply power.

3

WCS-232 can get the power from USB cable
connected to the USB port on the PC.
When both WCS-232 is powered up, they will be
connected using Bluetooth. This is when you can
start using the serial port.

6.2 Environment Setting

Since WCS-232 is connected to the serial port,
serial related settings (baud rate, data bit, parity
bit, stop bit, and flow control) and RF related
configurations (name of the device, operation mode,
target address) are required to be set. Regarding
RF connection settings, if WCS-232 is not trying to
connect to other WCS-232 but Bluetooth device from
other companies or when trying to reset the settings
to the factory default, it is required.

Proceed with Microsoft Visual C++ 2005 SP1
Redistributable Package installation.

After WCS-232 Setup Utility installation is complete,
click WCS-232 v5.0 Setup Utility v5 from the Start

7. Operation Environment Configuration

7.1 How to configure

Dedicated WCS-232 v5.0 configuration utility can
be used to modify communication speed, parity,
stop bit, device name, and operation mode.

■ Retrieve settings

① Connect WCS-232 to COM port and supply power to

the unit.
② Set switch in WCS-232 to Setup Mode.
③ Run WCS-232 v5.0 Setup Utility
④ From the utility, click Connection then COM Port at

the top of the menu to select the port to connect.

⑤ When successfully completed, “Read from flash is

success” message will appear.

■ Pairing Role

Select Master/Slave mode

■ Bluetooth Address

Current Bluetooth address can be checked. The target
Bluetooth address can be checked and set.

■ Pin Number

When connecting to the Bluetooth device, this pin is required.
Up to ASCII 16 characters can be set for a pin number.

■ Connection Mode

WCS-232 v5.0 supports “1:1 connection” a n d “connection
waiting” modes.
In 1:1 connection mode, connection is established when
the add re s s of the Bluetoot h devic e is ent ered manua l ly.
In connection waiting mode, When a target device is
not specified, it will look for new devices automatically.

3. When the “File Load” button is clicked, following
dialog box will appear.

4. When you click on the “Firmware Upgrade” button, it will

upload the firmware and show the progress from the bar.

5. After uploading the firmware is completed, the
following message will appear.

1-2 Check the pin wiring

• Data transmit/receiving devices are separated to
DTE (Data Terminal Equipment) device and DCE
(Data Communication Equipment) device. Generally, a
terminal such as a PC is a DTE device and a data relay
system such as a modem is a DCE device. According
to RS-232 standard, when DTE device is required to
connect to a DCE device, two devices are connected
directly or by 1:1 cable.

In other words, signal lines such as TX and RX or

signal control line should not be crossed but connected
directly. However, when two same kind of devices,
such as DTE and DTE, or DCE and DCE devices needs
to be connected, cross cable (often called the null
modem cable) is used. This cable is used to connect
TX with RX signal lines and cross connect other
signal control lines.

WCS-232 v5.0 is a DCE device required to be connected

to a PC directly. Therefore, if it needs to be connected
to a DTE device, it can be connected to a DTE device
directly or use a 1:1 cable. However, if it needs to be
connected to a DCE device or a modem, a cross cable
is required to be used.

2. Data loss or dysfunction

■ Save settings

① Click Apply button to save the settings in the device

memory.

② After it is saved, “Write to flash is success” message

will appear.

③ Click on the OK button to save the settings in the

device memory and close the windows.

7.2 Operation Setting

■ Serial Port

Set ser ial commu n icat ion config uration for SPP (Ser ia l Port
Profi le).

9

■ Device Name

A device name can be given here with up to 16 ASCII
characters.

■ Connection Timeout

Set a given period of time until the Bluetooth device
searches and connects.

8. Firmware Upload

1. WCS-232 v5.0 unit and the DFU (Device Firmware
Upgrade) file is required to upload a firmware.

2. Select F/W upgrade tab.

Appendix : Troubleshooting

1. Things to check when communication is not established.

1-1 COM port setting

• WCS-232 v5.0 supports 8 data bits only. When the
host supports 7 data bits and even or odd parity,
WCS-232 v5.0 can be set to 8 data bits, no parity
(factory default state). However, it cannot be applied
to a device such as 7 bit USB dongle.

• Check whether both WCS-232 devices are set to the
same parity and stop bit. WCS-232 supports v5.0 no,
even and odd parity and 1 or 2 stop bits.

• RTS (Request To Send) and CTS (Clear To Send) signal
from RS-232 standard are used for data transmit/
receiving (Hardware Flow Control or Hardware
Handshaking) control purpose.

• WCS-232 v5.0 does not support the break signal from
RS-232, thus it cannot be used for the device which
requires such feature.

13

target Bluetooth device, but when the communication
environment is not good, resending packets will be
repeated resulting a delay in communication. When
a hardware flow control is not used, internal buffer
in WCS-232 v5.0 may receive more data than it can
handle, causing an overflow. Therefore when the
wireless environment is not good, it is recommended
to use the hardware flow control.

3. Delay in communication

3-1 Delay in converting to wireless signal

• When WCS-232 v5.0 converts a data from the
host to wireless signal, it takes about 30 msec.
This delay may be increased due to the wireless
connection environment. Additionally, when WCS­232 v5.0 receives a data it converts to the wireless
signal immediately. Therefore, sequencing data can
be divided and transmitted. To prevent this, Inter­Character Timeout feature is provided which is when
no data is received from the serial port, transmission
begins.

3-2 Wireless Environment

• The Bluetooth uses 79 channels to transmit a data
to avoid interferences. However, when there are
numbers of Bluetooth devices in a small area, trying
to send a large amount of data, data loss or error
may occur. WCS-232 v5.0 can use 1.2 AFH feature in
Bluetooth to avoid Wi-Fi interference, but depending
on the distance or the number of the devices, it may
have less effect in such environment.
