 +===== JTAG/SWD connections =====
 +
 +The EVAL-CN0359-EB1Z **J4** is the JTAG/SWD debug connector.  This JTAG/SWD connector is pin compatible with [[https://www.segger.com/jlink-debug-probes.html|SEGGER J-Link]] debug probe.
 +
 +The EVAL-CN0359-EB1Z JTAG/SWD debug interface only support SWD debug mode.
 +
 +====== Usage Instructions ======
 +
 +The CN0359 system runs using a 6V DC wall connector (EVAL-CFTL-6V-PWRZ) and will run automatically when the power on.  The system has two interfaces to show the conductivity and RTD results: LCD screen and RS-485 interface, and those two interfaces can working simultaneously as well.
 +
 +<note tip>The CN0359 usage is depend on the software version, maybe there have difference between following instructions and shipped CN0359, please check [[adi>cn0359-DesignSupport]] for latest software update download</note>
 +
 +The CN0359 has the following opinions which can be set by the user:
 +  * Excitation voltage
 +  * Excitation frequency
 +  * Track-hold setup time
 +  * Track-hold hold time
 +  * Temperature coefficient
 +  * Conductivity cell constant
 +  * RS-485 baud rate
 +  * RS-485 address
 +  * LCD contrast
 +
 +<note warning>Please check with the conductivity sensor excitation signal requirements in sensor's datasheet before connecting the sensor or changing the setting, to make sure no damage is caused by inappropriate setting.</note>
 +
 +===== LCD Screen and Encoder User Interface =====
 +
 +The LCD screen can show the measurement results and settings of CN0359, user interactive with CN0359 could be done using the LCD and encoder **S1**.
 +
 +==== General usage instructions ====
 +
 +The CN0359 LCD display area have 3 status with different meaning:
 +  * normal status (dark font with light background) ⇒ item normal displayed
 +  * reverse status (light font with dark background) ⇒ item has been selected
 +  * blink status (keep flipping between normal status and reverse status) → item has been selected and in value chang status
 +
 +The CN0359 encoder **S1** can be turned clockwise or counterclockwise (no mechanical stop), and can also be used as a push button. The following is the encoder operating meaning:
 +  * turn clockwise at reverse status ⇒ change selection to next item.
 +  * turn clockwise at blink status ⇒ increase value
 +  * turn counterclockwise at reverse status ⇒ change selection to previous item
 +  * turn counterclockwise at blink status ⇒ decrease value
 +  * push button at reverse status ⇒ enter selected item
 +  * push button at blink status ⇒ exit blinked item
 +
 +<note>
 +There have two exception dialogs:
 +  * home dialog ⇒ no selected item in this dialog, push button will enter setting menu
 +  * LCD contrast setting dialog ⇒ in case the LCD display abnormal there is no blinked item in this dialog, turn encoder clockwise/counterclockwise will increase/decrease LCD contrast, push button will return
 +</note>
 +
 +The CN0359 have a buzzer on PCB, it will beeping when value limit reached or notify asserted.
 +
 +==== CN0359 start up and LCD contrast ====
 +
 +The CN0359 LCD screen contrast can be set by user, if the LCD contrast value set improper it will cause LCD display murky dull or have crosstalk, in this case user need to recover LCD contrast blindly, the following step can adjust LCD contrast blindly:
 +  - power up CN0359, the CN0359 will beep for 50ms immediately, this means all setting is right, flash disk is good.
 +  - the LCD should be showing the splash screen for 3s, maybe LCD show nothing or black screen if the contrast set improper, please push encoder button **S1** within 3s from powering on in splash screen.
 +  - the CN0359 will beeping 100ms two times, interval 100ms, this means the CN0359 entered LCD contrast setting status
 +  - turning the encoder **S1** clockwise/counterclockwise will increase/decrease LCD contrast, set the LCD display to clear and sharp
 +  - push button **S1** return to setting dialog
 +  - enter "reurn to home" menu item, CN0359 LCD will display properly and contrast setting will be saved
 +
 +==== Buzzer and Alarm ====
 +The EVAL-CN0359-EB1Z board have a buzzer **U2** on it, the buzzer will beeping in the following cases:
 +  * notify beeping 50ms at power up
 +  * notify beeping 200ms when from splash screen entering home dialog
 +  * notify beeping 100ms twice, interval 100ms, when button pushed at splash screen, entering LCD contrast setting dialog
 +  * alarm beeping 50ms for 5 times, interval 50ms when startup internal error, then means all the settings restore to default value, if this error asserted, please set all the settings to requirement
 +  * alarm beeping 10ms at home dialog when RTD error, if this error asserted, please check RTD connection
 +  * alarm beeping 100ms at home dialog when conductivity sensor error, if this error asserted, please check conductivity sensor connection
 +  * notify beeping 10ms if encoder turned to against software limit
 +
 +
 +
 +===== RS-485 Interface =====
 +
 +The RS-485 interface can connect multi (up to 254) CN0359 in the same RS-485 network, in the following chapter the CN0359 in the RS-485 network will be called client, the PC or any type of RS-485 device who can initiate the communications will be called host. Please notice: because the CN0359 use the single duplex mode RS-485 network, so there only one device can send the data at the same time, otherwise the RS-485 network will involve into the signal conflict, this will cause unpredictable result. In usually the CN0359 RS-485 network have only one host, if you have multi host in the network, please make sure there is no conflict occur in any time.
 +
 +The in the RS-485 network all the clients will keep in receive status in idle time. The client only send data when it response the right command.
 +
 +<note important 80%>
 +The EVAL-CN0359-EB1Z board RS-485 address can only be set by LCD interface.  Make sure you set the address first before trying to send RS-485 commands to the board.
 +</note>
 +==== RS-485 command usage ====
 +
 +<note tip>In order to use the RS-485 interface, a terminal program such as [[http://www.putty.org/|Putty]] or [[https://ttssh2.osdn.jp/index.html.en|Tera Term]] must be used. Please check the software settings before start, to make sure the terminal program output data stream on UART line can satisfy the following command format exactly.</note>
 +
 +The CN0359 command format is following:
 +
 +**SYNOPSIS**
 +
 +**address** **command** [options]  
 +
 +**DESCRIPTION**
 +
 +**address** is the integer value of CN0359 address, range from 1 to 254, the **address** should be issue before any command to wake corresponding CN0359 to receive **command**
 +
 +<note tip>
 +The CN0359 RS-485 interface use char '\n' LF (Line Feed) as ending character, that means the CN0359 will response the right command immediately after received char '\n', to prevent the half duplex RS-485 signal conflict, please make sure the char '\n' is the last byte send to CN0359 in each command string. Some of serial port terminal software add '\n' char to output stream when you press return key, if the software can not append '\n' automatically please send the command string in hexadecimal format append with 0x0a.
 +
 +The CN0359 use char ' ' space character as delimiter, please make sure no ' ' space character lost in command string.
