UIF-420A

- When CUBLOC is used as the main controller, since the commands such as PRINT and GETPAD are supported to facilitate the use of the UI.

- When this product is used with other main controllers (MCUs), it still provides a friendly UI, as data is transmitted through UIF-420A to be displayed on the LCD, and input typed on UIF-420A is transmitted to the main controller.

2. The Product’s Main Features

1) Key inputs are transmitted through SPI or RS232 protocol.

2) A built-in 20 x 4 character LCD on which I

C/SPI or RS232 protocol can be displayed

3) Software-controlled backlight ON/OFF

4) Four (4) on/off LEDs

5) A buzzer sound that can be controlled down to milliseconds

6) Key buzzer sound ON/OFF feature

7) All keys’s working condition and each key value can be checked.

8) RS232C communication speed can be selected from 4800 to 115200 bps.

(* A new switch setting takes effect only when power is turned off and on again.)

#1 --> Via RS232 communication RS232 MODE transmits key value and displays English letters, symbols and numbers on the character LCD. On the other hand, the I2C/SPI MODE uses SPI communication to transmit key value, and or uses I2C communication to display English letters, symbols and numbers on the character LCD.

#2 --> Whenever a key is pressed, a short buzzer sound is made. This buzzer sound can be turned on/off using switch 5 (SW5).

#3 --> When the power is turned on with SW6 in ON state, the UIF checks the status of all the keys. If there is a problem, such is displayed on the character LCD as “KEY STATE: NO-GOOD”. When all keys operate normally, the character LCD displays: “KEY STATE: GOOD”, “KEY VALUE:”. And when the key is pushed, the key value is displayed in decimals. (Using this mode, one can find out the key value that was transmitted to SPI or RS232.)

9. LCD Control Commands

When an ASCII code is sent to UIF, the corresponding ASCII code’s content is displayed on the LCD screen. But when you want special effects such as changing the position of the cursor or clearing the entire screen, you need to use a control code.

UIF’s LCD control command begins with an escape code (ESC which is represented by HEX code 1B) followed by one English character, which is followed by necessary parameters.

▌How to connect CUBLOC and UIF-420A via I2C or SPI connection

CUBLOC (CUSB-22R) and UIF-420A are connected as follows:

RS232C download Keypad (SPI)

CUNET (I2C) AC220V Power Input 9V DC Power Input

Set UIF-420A’s dipswitches as in the picture below (i.e., only SW4 ON, the rest OFF).

By setting SW4 ON, select I2C (CUNET) communication. Remember that you MUST turn the power off and on again after a new dip switch setting, as the new dipswitch setting is read in when the power is turned back on.

▌Converting Scan Codes to Meaningful Data using a Table

User Interface Panel User Manual

UIF-420A

<The original key scan codes of UIF-420A>

As you can see in the above picture, scan codes are random values unrelated to the displayed key labels on the product. Therefore, it is better to use converted values.

For example, since a value of 3 is transmitted when the key labeled “1” is pressed, using the table conversion we can convert the value 3 to 1. In this manner, the other keys’ scan code can be converted to respective corresponding values. This process is called “table conversion.”

Const Device = CB280

Dim SCODE1 As Byte

Dim SCODE2 As Byte

Dim SCODE3 As Byte

Const Byte SCANCODETB = (&HFF,19,15,1,2,3,20,16,_

UIF-420A

<This source code is from UIF420A_TEST2.CUL file, which can be downloaded from website

www.comfiletech.com

’s UIF420A page.>

Owing to the above program (i.e., source code), the UIF’s keys’ values are converted as shown in the picture below.

That is, when a number key is pressed, the code of same value (as labeled) is transmitted; and other keys when pressed transmit a values larger than 10.

<The Key Code Values obtained via Table Conversion>

Regarding 2-Byte Reception

In this program, there is a command which transmits key data in 2 bytes. Originally a scan code is only 1 byte. But here the original byte’s inverted value is sent together with the original byte to prevent error or noise that may happen during communication.

PRINT 27,72

Once this command is executed, whenever a key is pressed a 2-byte value is transmitted. The above source code includes a part which compares the original byte and its inversion, and ignores the transmitted value if the two values differ.

#. UIF-420A Beginner’s Guide (when RS232C is used)

▌How to connect CUBLOC and UIF-420A via RS232C

When CUBLOC (CUSB-22R) and UIF-420A are far apart, it is safer to use RS232 connection to send and receive data. The two devices are connected as shown in the picture below.

Here the RS232 cable should be a cross cable where both ends are of DSUB-9pin-MALE type. Cross cable is a type of RS232 cable where the Pin 2 and Pin 3 are crossed.

When UIF is used in the RS232 mode, first the RS232 channel has to be opened using the OPENCOM command, and then the display type has to be specified using the SET UIF command.

When a key is pressed, data is received via RS232 Ch1. The data value can be checked using the GET command.
