2.1.1 Power Through DB-9 Jumper
Power through DB-9 Jumper pictured in
power through DB-9 option, see table 1 on the following page for display module voltage requirements.
2.2 Power/Data Connector
25 requires five volts for the standard display module, between nine to fifteen for the wide voltage (V)
and between nine to thirty-five volts for the wide voltage with efficient power supply module (VPT). The
voltage is applied through pins one and four of the four pin Power/Data connector. Pins two and three are
reserved for serial transmission, using either the RS-232/TTL or the I
been selected by the Protocol Select Jumpers. Pins two and three may be reversed by changing the Legacy
Matrix Orbital
In order to provide power through pin 9 of the DB-9 Connector you must place a solder jumper on the
The Power/Data Connector provides a standard connector for powering the display module. The LK204-
WARNING Do not apply voltage through pin 9 of the DB-9 connector
AND through the Power/Data Connector at the same time.
