Connecting LK202-25

Regular Voltage

Power is applied to the white or brown four pin SIP connector as follows:

Pin 1: +5Vdc

Pin 2: = SCL (I²C clock)

Pin 3: = SDA (I²C data)

Pin 4: Gnd

If the sole data source is via the RS-232, the data input is via the DB9 connector. Pins 2 and 3 are not used.

Wide Voltage Option (V)

Power is applied to the white or brown four pin SIP connector as follows:

Pin 1: +7 - +15Vdc

Pin 2: = SCL (I²C clock)

Pin 3: = SDA (I²C data)

Pin 4: Gnd

If the sole data source is via the RS-232, the data input is via the DB9 connector. Pins 2 and 3 are not used

WARNING:

DO NOT APPLY ANY POWER WITH A REVERSED CABLE.

DO NOT APPLY AN VOLTAGE OTHER THAN THE SPECIFIED VOLTAGE.

DO NOT USE ANY CABLES OTHER THAN THE CABLES SUPPLIED BY MATRIX ORBITAL, UNLESS YOU ARE AWARE OF

THE MODIFICATIONS REQUIRED.

DO NOT UNDER ANY CIRCUMSTANCES USE AN UNMODIFIED FLOPPY DRIVE POWER CABLE.

DB9 Connector Pin Out

RS - 232 port: This connector is wired so that a standard “straight through” 9 pin D-sub cable may be used to connect the

modules on a standard serial port such as comm ports on PCs. Note that this device complies to the EIA232 standard in

that it uses signal levels from +/- 3V to +/- 12V. It will not operate correctly at TTL (0 to +5V) levels.

Note: Signals are shown as interpreted by the Liquid Crystal Display module.
