Configuration connector
WS103 uses a RS232 port in order to be configured.
The USB/RS232 converter cable will be used together with a WS Wireless Configurator tool.
Connect USB/RS232 converter cable
Prepare communication between the PC/laptop and the USB/RS232 converter cable to allow the
configuration of the WS103 before connecting USB/RS232 converter cable to PC/laptop:
1. Go to http://www.ftdichip.com/Drivers/VCP.htm and download and install the latest VCP drivers (up
to version 2.12.10).
2. Connect RS232/USB converter cable.
Before opening the WS Wireless Configurator verify if the FTDI driver is correctly installed (check Version
in Device Manager) and make sure the RS232/USB converter cable is connected.
CAN bus termination
In each CAN bus system, signal reflections at the end of a wire or cable can cause interference, which is
one reason for transmission errors.
To minimize these reflections a terminator is placed at each end of a transmission line. This terminator
has to match the characteristic impedance of the transmission line.
In CAN bus networks, normally unshielded twisted pair cables are used for signal transmission. These
cables have a characteristic impedance of approximately 120 Ohms. Thus a resistor of 120 Ohms has to
be placed at each end of the CAN bus line between CAN-High and CAN-Low to reduce the reflections and
enable correct communication.
Connect power supply
1. Connect the power supply to the WS device. For the power connector assignment, refer to
CAN /
Power connector
on page 11 and
RS-232 connector
on page 11.
2. Connect the power supply to an electrical outlet.
