WARNING Do not apply voltage through pin 9 of the DB-9 connector

AND through the Power/Data Connector at the same time.

2.2 Power/Data Connector

ThePower/Data Connector providesastandard connectorfor powering the display module. The GLK240128-

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 volt-

age 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

C protocol, depending on what has

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.

Pin 1 PWR (See table ?? on page ??)

2 Rx \ SCL (I

C clock)

3 Tx \ SDA (I
