2.1 Power/Data Connector
ThePower/Data Connectorprovides a standard connector for powering the display module. The GLK12232-
25 requires ?ve volts for the standard display module. Exten
ded voltage options are available as an add-on,
please contact a sales representative for additional information. 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 I2C protocol, depending on what has been selected by the
Protocol Select
Jumpers.
