Figure 10: Twelve Volt Power Cable NOTE The connector provided does not allow access to the middle two pins, which are used for I C communications. If this functionality is required, Matrix Orbital suggests a suitable connector be wired. 2.1.4 Power Connection (DB-9 Connector) The display can be powered via pin 9 on the DB-9 connector. -
Page 14: Communications
Note that this device complies with the EIA232 standard in that it uses signal levels from 12V to 12V. It can also operate correctly at TTL (0 to +5V) levels. To use standard RS-232 no modifications are required. For TTL, please refer to the Table below. Figure 13: RS-232 Pinout Matrix Orbital GLC24064... - Page 15 RS-232 communication can also be achieved through the middle two pins of the power connector. Figure 14: Power Connector Table 5: Connector Pinout Pin 4 Pin 3 Pin 2 Pin 1 Ground To allow this, the jumpers must be set as indicated below. Figure 15: RS-232 Matrix Orbital GLC24064...

Page 17: Ack
Matrix Orbital module processes data. Basically, the reason why a Matrix Orbital module might fail to receive a byte correctly is that it was unable to process the byte previous before the failed byte was transmitted. Because the module cannot possibly know that it would be unable to store the byte before the next byte was received, it cannot know to not ACK. -
Page 18: Displaying Text
GLC24064 please read sections 7.2 and 7.3. 3.1 General Text is displayed on the GLC24064 using fonts saved in its internal flash memory. The display is supplied with a 5x7 font installed. If this is suitable, then there is no need to install any other fonts. -
Page 19: Text Commands
"Set font metrics" command in the display memory (normally, the bottom right character position - default value for the GLC24064 is 64). 3.3.2 Auto Scroll Off (254 82) When auto scrolling is disabled, text will wrap to the top left corner of the display area. -

This command sets the drawing color for subsequent graphic commands that do not have the drawing color passed as a parameter. The parameter [color] is the value of the color where white 0 Hex, and black is 255 Hex. NOTE All non-zero values will display as black. Matrix Orbital GLC24064... -

0x00, 0x08, 0x10, etc. It is not possible to write a 10 x 10 bitmap to the screen at pixel location (13,13). It is however, possible to write a 16 x 10 bitmap to the screen at pixel location (24,13). The user may wish to use flow control during direct screen bitmap writes to avoid possible buffer over- flow. Matrix Orbital GLC24064... -
Page 24: Initialize Strip Chart (254 106 [Ref][X1][Y1][X2][Y2])
With text the strip chart the user can produce a ’marquis’ effect. NOTE If the strip chart is used with text, Matrix Orbital recommends the use of a 6 or 7 pixel wide fixed width character set with each character placed 8 pixels from the start of the previous one. -

Operationally, there is one important difference between the Matrix Orbital file system and that of a PC. While a PC will allow fragmentation of its files across the available file space, the Matrix Orbital file system takes great care to ensure that all parts of a file are stored together. This system works well to maximize storage space and operational efficiency. -
Page 26: Using Mogd.exe
5.2 Using mogd.exe The Matrix Orbital Interface program "mogd.exe", which is provided on the disk and the website, gen- erates and saves fonts larger than 14 pixels in height. It is also used to save graphic images (bitmaps) to the display. -

Page 29: A Sample Font File
Below is a short sample font file containing only the letters "h", "i" and "j". First we need to define the font size. For this example we’ll use a 5x7 pixel font. Next, we have to draw the bitmaps for each of the characters.
