4 Hardware
Extended Communication/Power Header
The Extended Communication/Power Header provides a standard connector for interfacing to the
GLK240128-25/GLT240128. Voltage is applied through pins one and four of the four pin
Communication/Power connector. Please ensure the correct voltage input for your display by
referencing the electrical specifications in Table 62 before connecting power. Pins two and three are
reserved for serial transmission, using either RS-232/TTL communication or clocking data through the I²C
protocol, depending on what has been selected by the Protocol Select Jumpers. Pins five and six can be
used for serial transmission hardware flow control, and are ignored for I²C communications. The Molex
22-04-1061 style header used can be mated to a number of connectors.
Serial DB9 Connector
The GLK240128-25/GLT240128 provides a DB-9 Connector to readily interface with serial devices using
EIA232 standard signal levels. It is also possible to communicate at TTL levels of 0 to +5V by setting the
Protocol Select Jumpers to TTL. As an added feature it is also possible to apply power through pin 9 of
the DB-9 Connector in order to reduce cable clutter. A standard male DB9 header will provide the
perfect mate for this connector.
