Features Communication/Power Connector (ELK204-7T) The ELK Series comes with a simple four pin TE 282834-4 style terminal block to fulfill both communication and power needs. Voltage is applied through pins one and four while pins two and three are reserved for serial or I2C transmission. This versatile header can be connected to a variety of cables for a simple interface to any host.
Commands An extensive list of commands and additional display information* can be found in the LK204-7T-1U and GLK19264A-7T-1U display manuals at www.matrixorbital.ca/manuals. Quick Connect Serial Connections The serial interface provides a classic connection for RS232 or TTL development. 1. Set the Protocol Select jumpers. RS232: Connect the three jumpers** in the 232 protocol box with the zero ohm jumper resistors provided or an alternate wire or solder solution.
Troubleshooting Display If your display is powered successfully, the Matrix Orbital logo, or user created screen should display on start up. If this is not the case, check out these tips. • • • Check that power to your device is wired correctly using the Com/Power Pinout. Ensure the contrast is not too high or too low and that the backlight is on. See the Manual Override section to reset these values to default.
