2 - HUMAN-MACHINE INTERFACE
The D510C human-machine interface
consists of 3 elements:
- The USB link
- The I/O
- The LEDs

2.1 - Communication
USB link
The EasyReg software and the D510C
communicate via a USB cable (Universal
Serial Bus).
Warning: In SHUNT operation,
please use a USB isolator to connect the
PC to the D510C.
Do not connect the USB during the
starting if the DC supply of the AVR is
switched off.
2.2 - Analog I/O
This part of the board allows the operator to
use the inputs to make manual settings and
the outputs to check certain data or to
indicate whether certain AVR functions are
working correctly or not. An external voltage
(0 V – 10 V) is present which can be used as
a reference for an electronic device.
The minimum analogic input setting is 0%
and the maximum is 100%.
External by setting is either:
- from an external potentiometer (1k Ω),
- 4 - 20 mA,
- 0 - 10 V.
The two analog inputs can also be used to
achieve digital fun / -.
NB : Make sure that the voltage applied on
analogue input does not exceed 10V. For
applications requiring the use of +/-10V, the
D510C must be configured as 0-10V and the
following schematic must be used.
