2.1 DB-9 Connector
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.
2.1.1 Power Through DB-9 Jumper
Power through DB-9 Jumper pictured in
power through DB-9 option, see table 1 on page 8 for display module voltage requirements.
Matrix Orbital
The LK162-12 provides a DB-9 Connector to readily interface with serial devices which use the EIA232
In order to provide power through pin 9 of the DB-9 Connector you must place a solder jumper on the
