Page 14: Firmware Upgrade
3.1 Firmware Upgrade Beginning with revision 8.1, the firmware of the GLK24064-25/GLT24064 can be upgraded in the field. Alternatively, the changes to the filesystem and subsequent commands can also be reverted by downgrading the firmware to revision 8.0 using the same process. -
Page 15: Hardware
Figure 7: Extended Communication/Power Header The Extended Communication/Power Header provides a standard connector for interfacing to the GLK24064-25/GLT24064. Voltage is applied through pins one and four of the four pin Communication/Power Header. Please ensure the correct voltage input for your display by referencing the electrical specifications in Table 62 before connecting power. -
Page 16: Power Through Db9 Jumper
DB-9 Jumper labelled R42, as illustrated below. This connection can be made using a zero ohm resistor, recommended size 0603, or a solder bridge. The GLK24064-25/GLT24064 allows all voltage models to use the power through DB-9 option, see the specifications in Table 62 for voltage requirements. -

Tx (A) Figure 12: RS422 Header The six pin RS422 interface header of the GLK24064-25-422/GLT24064-422 offers power and ground connections as well as two differential pair communication lines. Regular and inverted lines are provided for both receive and transmit signals. Power is supplied locally to the regular variant while the –VPT can receive power over a distance. -
Page 19: Glk Model
Row 5 Gnd/Vcc* To facilitate user input, the GLK24064-25 provides a Keypad Interface Connector which allows a matrix style keypad of up to twenty-five keys to be directly connected to the display module. Key presses are generated when a short is detected between a row and a column. When a key press is generated, a character specific to that key press is automatically sent on the Tx communication line. -

4.5 GLT Model Touch Screen The GLT24064 facilitates user touch input in one of two distinct ways. Coordinate mode will report events by supplying their exact position on the screen. Region mode will report events within defined boundaries on the screen. Both modes are outlined below. Coordinate Mode In coordinate mode all touch events are reported using three single byte values. -

Page 28: Font File Creation
Font files alter the style of text and appearance of the display. By default, a Matrix Orbital graphic display is loaded with a small filled font in slot one and a future bk bt 16 style in slot two. Both are available in the software download section at www.matrixorbital.ca. The easiest way to create, add, or modify the fonts of any graphic display is through the MOGD# tool. -
Page 29: Bitmaps
The character data is a binary graphical representation of each glyph in a font. Each character is drawn on a grid containing as many rows as the height specified in the header and as many columns as the width specified in the character table. Cells are drawn by writing a one in their location and cleared by setting a value of zero. -
Page 30: Bitmap File Creation
Bitmap File Creation example Bitmap File Creation In addition to fonts, Matrix Orbital graphic displays can also hold a number of customizable bitmaps to provide further stylistic product integration. Like font files, bitmaps files are most easily uploaded to a display using MOGD#. -

Page 41: File Upload Protocol
Once a bitmap or font file has been created and paired to its command it must be sent using a file protocol developed specifically for Matrix Orbital displays. Once a file upload command has been sent requesting a unique reference number and specifying the file size required, the display will respond indicating whether it has enough room to save the file or not. -
Page 42: Xmodem Upload Protocol
XModem Upload Protocol In addition to its original simple upload format, Matrix Orbital has added an XModem based protocol. This facilitates much faster download speeds by increasing the packet size from 1 byte to 128 bytes greatly increasing throughput. Though a protocol similar to the original upload scheme is used, a two byte CRC check is preformed at the end of each packet in place of the byte echo system. -
