2.1 DB-9 Connector

The LCD2041 provides a DB-9 Connector to readily interface with serial devices which use the EIA232

standard signal levels of ± 12V to ±12V. 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. However, in order to accomplish this you must

set the Power Through DB-9 Jumper.
