Chart 2-4: pin layouts of the the digital inputs and outputs

2.6.1 Connecting the digital inputs

At the inputs IN1 to IN4 any external voltage between VCC and GND can be applied. As

soon as the voltage difference between INx and GND is more than 3.0 V, the AnaGate CAN

Gateway interprets the input as logically HI otherwise LOW.

2.6.2 Connecting the digital outputs

The outputs are implemented as open collector drivers. If a output is active, it is pulled down

to GND. In the inactive condition the output is floating.

In principle the maximum current of each individual output is 400mA. For thermal reasons is

the sum of all output currents is limited to 500mA. The outputs not short-circuit proofed, and

must f be protected with a pre-resistor.
