The Communication/Power Header provides a standard connector for interfacing to the
LK202-
25/VK202-25.
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 Voltage Specifications
before connecting power. Pins two and three are reserved for serial transmission, using either the RS-
232/TTL or clocking data through the I2C protocol, depending on what has been selected by the
Protocol
Select Jumpers.
The versatile Tyco 640456-4-LF
style header used can be mated to a number of
connectors, the Molex 22-01-3047 for example.

The LK202-25/VK202-25
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.
*Note:
Do not apply voltage through pin 9 of the DB-9 Connector AND through the Communication/Power Header
at the same time.
