7. Electrical Interface Characteristics
The following chapters are organized in terms of similar functions, not interfaces. There is no
chapter about the DIOP interface, for example. However, each chapter will mention which
interfaces are relevant to it. Information about the DIOP interface for example, can be found in the
Digital Inputs, Digital Output and PWM Output sections below.
7.1. Analog Inputs
There are two types of Analog Inputs, namely: type B and type A making up a total of 12 Analog
Inputs. Type B measures voltage, while Type A measures current. After their respective filters, the
values are fed directly to the microprocessor’s A/D converter. Ports 1 and 2 have 12 bits resolution,
instead of 10.
