2.1 CAN
The CAN controller of the microcomputer is connected to the CAN FD transceiver
(TJA1044GT). It supports CAN physical layer. Also, CAN bus signal is connected to DSUB 9pin
female connector.
One terminal can be selected by using jumpers from maximum of three multipurpose terminals, and
can be connected to CAN transceiver.
Only one line must be shorted in each jumper.

About the MODE signal
The MODE signal is connected to the STB terminal of the CAN driver IC (TJA1044GT).
If not controlled by the port, changing the jumper pin to 2-3 short circuit will be fixed to Low, and it
can always be in the normal state.

2.2 Serial select
It can be connected by selecting the microcomputer's UART terminal to "LCD",
"RS-232C", "USB Serial Conversion", and "LIN".
The terminals for using UART can be selected by jumpers.
The connection destination of each UART can be selected with the jumper switch shown
below.

2.2.1 LCD
Words can be displayed on LCD panel by sending data to UART that is connected to LCD.
"Binary mode" to display hexadecimal and "ASCII mode" to display ASCII characters can be
selected by the DIP switch (SW1).
Initial screen displays when you press the reset switch on CPU board.
UART Communication Specifications
・Baud Rate 115.2Kbps (Fixed)
・Data Length 8ｂｉｔ (LSB First)
・Parity None
・Stop Bit 1bit
・Flow Control None (continuous transmission enabled)
Binary Mode 1 (SW1_1:ON, SW1_2:ON, SW1_3:Any)
It displays the hexadecimal data as sent with entering space between 1Byte data.
It can display 10Byte in 1 screen. It scrolls 1 line when it received 11Byte of data.
(example）URTH?TX = 0x01; TXWait();
URTH?TX = 0x02; TXWait();
・・・・・・・・・・
URTH?TX = 0x0A; TXWait();

Binary Mode 2 (SW1_1:ON, SW1_2:OFF, SW1_3:ON)
It displays the hexadecimal data as sent without entering space between 1Byte data.
It can display 16Byte in 1 screen. It scrolls 1 line when it received 17Byte of data.
(example）URTH?TX = 0x01; TXWait();
URTH?TX = 0x02; TXWait();

ASCII Mode Ver.2 (SW1_1:OFF, SW1_2:Any, SW1_3:Any)
It displays the characters as sent.
It can display 16 characters in 1 line. It scrolls 1 line when it received 17th character or
linefeed code (0x0D: \r ).
(example）URTH?TX = ‘F’; TXWait();

2.2.3 USB Serial Conversion
UART that is connected to "USB serial conversion" can communicate with the COM port of PC
through USB controller (FT230).
If the USB driver is a PC connected to the Internet, the latest driver is automatically installed
by "Windows Update". Please wait until the pop-up "Device is ready to use" appears.
If the driver is not installed, it can be downloaded from the following URL.
http://www.ftdichip.com/Drivers/VCP.htm
Recommended UART communication specification
・Baud rate 115.2Kbps
・Data length 8bit (LSB First)
・Parity None
・Stop Bit 1ｂｉｔ
・Flow Control None

2.3 Push Switch
4 interrupt signals can be connected to microcomputer's interrupt terminals. The signal can
be set to High by pressing H button, and to Low by pressing L button. It becomes High by reset
signal of the CPU.
Also, it has chattering prevention circuit.
The interrupt signals are disconnected by taking each jumper pin out.

2.5 Power
Connect bundled AC adapter (+5V) to AC Jack. You do not need to connect to the AC Jack
on the CPU board.
Using the regulator from the power supplied from here, + 12V and + 3.3V are also generated.
Power supply source can be changed by JP2 and JP3.
