1.4.2. USB, CAN and SERIAL Board
The optional carrier board includes the standard elements and the following ones:
Serial ports (TTL, RS-232, RS-422, and RS-485)
The TTL port is used for the short-range transmission of data. The port has a standard signal level
of 0 V through 3.3 V.
The RS-232 is used for the transmission of data. It defines the signals connection between the data
terminal equipment (such as a computer) and the data circuit-terminating equipment (such as a
modem).
The RS-422 (ANSI/TIA/EIA-422-B), a four-wire configuration, specifies the electrical characteristics
of the digital signaling circuit. It can transmit data at rates as high as 10 Mbit/s or may be sent on
cables as long as 1500 meters. Some systems directly interconnect and may be used to extend
the range of an RS-232 connection.
The RS-485 (ANSI/TIA/IEA-485) is a two-wire or four-wire differential serial communication port. It
is often used in electrically noisy environments.
Microcontroller MCU
The source and control assembly are equipped with an MCU on the carrier board. It is provided to
transmit data from the receiver module through the communication ports.
USB interface
The USB interface is a compatible 2.0, full-speed 12-MBit/s port. This interface emulates a VCP
(virtual COM port) used as a serial port.
Application and reset switch
The reset switch restarts the module. This can be used as an alternative to cycling the power.
Serial link configuration DIP switches
The source and control assembly is equipped with ten DIP switches. Five of them are used to
configure serial link 1 (see
Figure 2 and
Figure 3).
CAN bus interface
The CAN bus is implemented via a differential pair. The ISO 11898 standard describes the CAN
technology. The interface has a level of 3.3 V.
