LF Performs a line feed command. The vertical cursor position is moved down one line. Font mode only. CR Performs a carriage return. The horizontal cursor position is moved to the left most column. Font mode only. ESC + C + Xpos + Set cursor co-ordinates. X = horizontal pixel position (0-255). Y = vertical byte position (0-7). Ypos Cursor range is dependent on VFD module connected. ESC + D + cmd Sets the display mode. ‘O’ = Turn Display On - this is the power on default. ‘F’ = Turn Display Off - the display contents are retained. The graphic modules contain two displays areas, which allows for writing to a hidden screen, whilst display another. This can help improve the appearance of a slow display update. ‘1’ = Display screen 1 – power on default. ‘A’ = Write to screen 1 – power on default. ‘2’ = Display screen 2. ‘B’ = Write to screen 2. ESC + F + font Select font mode. All data transmitted to the controller is interpreted as character data. ‘1’ = 5x7 font ‘2’ = 10x14 font ‘3’ = 20x28 font ESC + G Select graphic mode. All data transmitted to the controller is interpreted as graphic data. Graphical data is displayed at the current cursor position in a vertical format (bit 7 = top, bit 0 = bottom). After each data write, the cursor x position is advanced by one pixel. ESC+ H Set data format as hex. All data transmitted to or from the interface module will be in a 2 byte hex format. This setting is retained in EEPROM. ESC + I Set data format as binary. This setting is retained in EEPROM. ESC + K + cmd Keyboard command. ‘A’ = Change keyboard mode to automatic send. A key response is transmitted from the controller each time a key is pressed. ‘M’ = Change keyboard mode to manual. No key response from the controller unless manually read. ‘R’ = Read keyboard – A key response is immediately transmitted from the controller. Keyboard responses takes the form of - “ESC + ‘K’ + byte1 + byte2”. st The 1 byte bits 3-0 = keyboard lines C3-C0, bit 7 = keyboard unchanged flag. nd The 2 byte bits 7-0 = keyboard lines C7-C0. ESC + L + level Set the display luminance:- ‘A’ = minimum luminance. ‘P’ = maximum luminance – power on default. Note: The number of luminance levels is dependent on the VFD module connected. rd ESC + M + icon + data Download icon. The 3 byte indicates which icon to create - ‘1’ to ‘8’. The icons are 16x16 pixels in size. The data (32 bytes) is in a vertical format. All icon data is retained within EEPROM. ESC + N + icon Write icon ‘1’ to ‘8’ at the current cursor position. ESC + P + byte Send single byte direct to the VFD module with control line C/D held high. ESC + Q + byte Send single byte direct to the VFD module with control line C/D held low. ESC + R Re-initialise controller to power on defaults. All error status flags are reset. The start-up string is executed from EEPROM. rd ESC + S + bytes Send start-up data to EEPROM. The 3 byte should indicate the number of bytes to send to the EEPROM (240 maximum). This data is executed upon each reset, re-initialise and power-up. rd ESC + T + bytes Transfer data to SPI port. The 3 byte indicates the number of bytes to send. Data is clocked out of the SPI port (DATA & CLK lines). After the data has been sent, a positive pulse is generated on the LATCH line. ESC + V Read controller status, response in the form of – “ESC + ‘V’ + byte”. bit 7 = Module type - GU300 (0)/GU800 (1) bit 3 = UART parity error bit 2 = UART overrun error bit 1 = UART framing error bit 0 = EEPROM locked ESC + W Wipe the current screen. ESC + Y + byte Set baud rate and parity. Baud Rate Bit 7 Bit 6 Bit 5 Bit 4 Parity Bit 3 The byte bits 2, 1, 0 are not used. 2400 0 0 1 1 NONE 0 4800 0 1 0 0 EVEN 1 9600 0 1 0 1 14400 0 1 1 0 19200 0 1 1 1 38400 1 0 0 0 ESC + Z Lock EEPROM. Once the required icons & communication settings have been sent, it is recommended to lock the EEPROM with this command. Any subsequent changes made to the EEPROM will be ignored. Unlocking can only be achieved by erasing the whole EEPROM, this is done by shorting the DTR & RXD lines at power on. Subject to change without notice NORITAKE ITRON INTERFACE CONTROLLERS MCBK10JRA
