422 receiver of serial line
Connect termination and forcing circuitery to RS
485 receiver/transmitter or to RS 422 receiver of
serial line
Does not connect on board Lithium battery to
optional Real Time Clock + SRAM circuitery.
*
Connects on board Lithium battery to optional Real
Time Clock + SRAM circuitery, allowing to keep
date, time and SRAM content even when power
supply is not present.
Does not connect 2.5 Vdc to signal MM PIN 7 of _*
socket ZC1.
Connects 2.5 Vdc to signal MM PIN 7 of socket
ZC1. If a grifo ^® Mini Module is installed, this
tension is used as reference voltage (Vref) for on
board A/D converter.
