2.1.1 Power Through DB-9 Jumper
Power through DB-9 Jumper pictured in
the 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
Connector Jumpers in order to be compatible with previous PCB revisions.

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 VK202-
WARNING Do not apply voltage through pin 9 of the DB-9 connector
AND through the Power/Data Connector at the same time.
