Jumper configuration:
Having configured Ardbox Analog HF as it is shown above, these are the features that are
available:
o Available communication protocols:
 Hardware Serial RS-485.
 I2C *If I2C is active I0.0 & Q0.6 are disabled
 SPI
 TTL
 USB
o Inputs: 8 out of 10 inputs, I0.0, I0.1 and 10.4 to I0.9. If using I2C I0.0 is also disabled
o Digital Outputs: All 10 outputs. If using I2C Q0.6 is disabled.
o Analog Outputs: From A0.0 to A0.6. If using I2C A0.6 is disabled
Hardware Serial RS-232
In order to enable the Hardware Serial RS-232 the total configuration of the Ardbox Relay HF

Note: The switches of the left
zone of the RS-485 don’t
interfere in the RS-232 HS, the
thing is that as pins 0 & 1 are
reserved for the RS-232, the
RS-485 is totally disabled. As it
is disabled, there is no point on
configuring these switches as
RS-485 mode
