2.1 Power

Warning:

Do not apply any power with reversed polarization.

Do not apply any 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.

Refer to the diagram below for this chapter.

5V jumper

Figure 2-1 Electrical Connections

2.1.1 Regular Voltage

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

Pin 1: +5V DC ± 0.25V

Pin 2: = SCL (I²C clock)

Pin 3: = SDA (I²C data)

Pin 4: Gnd

If the sole data source is via RS - 232, the data input is via the DB9 connector. In this case pins 2 and 3 are

not used.

2.1.1.1 Five volt Power Cable

If a GLK24064-25 module is used in a PC it is tempting to plug a spare power connector into the unit.

Don't do this! Wiring for the PC power connector and that required for the module are different as shown

in Figure 2-2 below.
