5.2 Using the CR Oscillator Circuit Pattern

There is a CR oscillator circuit pattern on the M37531T-ADS.

To use the CR oscillator circuit pattern, mount R3 and C5, and remove the coated wire of JP1, then

change the setting.

CAUTION

Note on Setting Up:

• Always shut OFF power before connecting this product. The power ON state could

destroy internal circuits.

As pins 5-6 and 2-3 of JP1 are shorted out by the coated

wire when shipped from the factory, use the oscillation of

OSC-2.

To use the CR oscillator circuit pattern, mount R3 and C5,

and remove the coated wire of JP1, then change the

setting as following.

When using CR oscillation: Short-circuit 4-5, 1-2

When using OSC-2: Short-circuit 5-6, 2-3
