1 Introduction Figure 1: GLK19264A-7T-1U Display The GLK19264A-7T-1U is an intelligent graphic liquid crystal display engineered to quickly and easily add an elegant creativity to any application. In addition to the RS232, TTL and I2C protocols available in the standard model, USB and RS422 communication models allow the GLK19264A-7T-1U to be connected to a wide variety of host controllers. Communication speeds of up to 115.
2 Quick Connect Guide 2.
2.2 Standard Module The standard version of the GLK19264A-7T-1U allows for user configuration of two common communication protocols. First, the unit can communicate using serial protocol at either RS323 or TTL voltage levels. Second, it can communicate using the Inter-Integrated Circuit connect, or I2C protocol. Connections for each protocol can be accessed through the four pin Communication/Power Header as outlined in the Serial Connections and I2C Connections sections below.
2. Make the connections. a. Connect the six pin female header of the Extended Communication/Power Cable to the Communication/Power Header of your GLK19264A-7T-1U. b. Insert the male end of your serial cable to the corresponding DB9 header of the Extended Communication/Power Cable and the mate the female connector with the desired communication port of your computer. c. Select an unmodified floppy cable from a PC power supply and connect it to the power header of the Communication/Power Cable. 3. Create.
2.3 USB Module The GLK19264A-7T-1U-USB offers a single USB protocol for easy connection to a host computer. The simple and widely available protocol can be accessed using the on board mini B style USB connector as outlined in the USB Connections section. Recommended Parts The External Mini USB cable is recommended for the GLK19264A-7T-1U-USB display. It will connect to the miniB style header on the unit and provide a connection to a regular A style USB connector, commonly found on a PC.
2.4 RS422 Module The GLK19264A-7T-1U-422 provides an industrial alternative to the standard RS232 communication protocol. Rather than single receive and transmit lines, the RS422 model uses a differential pair for the receive and transmit signals to reduce degradation and increase transmission lengths. Power can be transmitted at distance to a -VPT module or supplied from the immediate vicinity to a regular or –LV unit.
3 Software The multiple communication protocols available and simple command structure of the GLK19264A-7T1U means that a variety of applications can be used to communicate with the display. Text is sent to the display as a character string, for example, sending the decimal value 41 will result in an 'A' appearing on the screen. A single control character is also available. Commands are merely values prefixed with a special command byte, 254 in decimal.
Figure 7: MOGD# Command Example Again, the clear screen command is sent to a connected display, this time using the MOGD# Send Numeric function command style. Scripts can be run as a whole using the Play button from the toolbar or as single commands by selecting Step; once executed it must be Reset. Before issuing commands, it is a good idea to ensure communication with a display is successful using the autodetect button.
4 Hardware 4.1 Standard Model Extended Communication/Power Header Table 4: Extended Communication/Power Pinout Figure 8: Extended Communication/Power Header Pin 1 2 3 4 5 6 Function Vcc Rx (SCL) Tx (SDA) Gnd CTS RTS The Extended Communication/Power Header provides a standard connector for interfacing to the GLK19264A-7T-1U. Voltage is applied through pins one and four of the four pin Communication/Power Header.
Power Through DB9 Jumper In order to provide power through pin 9 of the DB-9 Connector you must connect the Power Through DB-9 Jumper labelled D, as illustrated below. This connection can be made using a zero ohm resistor, recommended size 0603, or a solder bridge. The GLK19264A-7T-1U allows all voltage models to use the power through DB-9 option, see the Voltage Specifications for power requirements.
4.2 USB Model Mini USB Connector Table 6: Mini USB Pinout Pin 1 2 3 5 Figure 11: Mini USB Connector Function Vcc DD+ Gnd The GLK19264A-7T-1U-USB comes with a familiar Mini USB Connector to fulfill both communication and power needs. The standard Mini-B style header can be connected to any other USB style using the appropriate cable. Most commonly used with a PC, this connection creates a virtual com port that offers a simple power solution with a familiar communication scheme.
4.3 RS422 Model RS422 Header Table 8: RS422 Pinout Pin 1 2 3 4 5 6 Figure 13: RS422 Header Function Gnd Rx (Y) Inv Rx (Z) Inv Tx (B) Tx (A) Vcc The six pin RS422 interface header of the GLK19264A-7T-1U-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 or –LV variants while the –VPT can receive power over a distance.
4.4 Common Features General Purpose Outputs Table 10: GPO Pinout Figure 15: GPO Header Pin 1 2 3 4 5 6 7 Function GPO 1 GPO 2 GPO 3 GPO 4 GPO 5 GPO 6 Vcc Pin 8 9 10 11 12 13 14 Function Gnd Gnd Gnd Gnd Gnd Gnd Gnd A unique feature of the GLK19264A-7T-1U is the ability to control relays* and other external devices using either one or six General Purpose Outputs. Each can source up to 10mA of current at five volts when on or sink 20mA at zero volts when off.
5 Troubleshooting 5.1 Power In order for your Matrix Orbital display to function correctly, it must be supplied with the appropriate power. If the power LED near the top right corner of the board is not illuminated, power is not applied correctly. Try following the tips below. First, check the power cable which you are using for continuity. If you don't have an ohm meter, try using a different power cable, if this does not help try using a different power supply.
5.3 Communication When communication of either text or commands is interrupted, try the steps below. • • • • • • • • First, check the communication cable for continuity. If you don't have an ohm meter, try using a different communication cable. If you are using a PC try using a different Com/USB Port. Next, please ensure that the display module is set to communicate on the protocol that you are using, by checking the Protocol Select Jumpers.

6.4 Fonts 4.1 Upload a Font File Dec 254 36 ID Size Data v8.0 Hex FE 24 ID Size Data ASCII ■ $ ID Size Data Upload a font to a graphic display. To create a font see the Font File Creation section, for upload protocol see the File Transfer Protocol or XModem Transfer Protocol entries. Default font is ID 1. ID* Short Unique font identification number, value between 0 and 1023. Size* Integer Size of the entire font file. Data Byte(s) Font file data, see the Font File Creation example.
Font File Creation Matrix Orbital graphic displays are capable of displaying text in a wide variety of styles customizable to suit any project design. Front 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 at www.matrixorbital.ca/software/graphic_fonts.
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. Starting at the top left, moving right, then down, eight of these cells form a character data byte.
6.5 Bitmaps 5.1 Upload a Bitmap File Dec 254 94 ID Size Data v8.0 Hex FE 5E ID Size Data ASCII ■ ^ ID Size Data Upload a bitmap to a graphic display. To create a bitmap see the Bitmap File Creation section, for upload protocol see the File Transfer Protocol or XModem Transfer Protocol entries. Start screen is ID 1.

X1 Byte Leftmost coordinate of bitmap. Y1 Byte Topmost coordinate of bitmap. Data Byte(s) Bitmap file data, see the Font File Creation example. Command Summary v8.
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#. However, the critical data component of the bitmap upload command is detailed below for reference. The bitmap data block is similar to that of a font. However, as a bitmap is a single glyph, only a simple two byte header is required.
