Additional hardware you will need#

Before we proceed, we need the following additional hardware to properly communicate with SimpleSwitch™ devices.

  • A RS232 adapter, e.g. standard conform USB-to-RS232 adapter

  • A Null modem cable

  • An Ethernet cable (CAT5 or better)

  • suitable SD-Card

Caution

Be sure to pick an USB-to-RS232 adapter that supports at least 5V signals. 1.8V (and even 3.3V) adapters may not work.

A known to be good adapter can be found here

SD-Card recommendations

We recommend using UHS-I (or better) SD-Cards between 8-32GB capacity. Cards above 32GB might face compatibility issues on some SoMs.

Connecting the hardware#

  • With the null modem cable connect the RS485/RS232 Connecter X1102 connector of the base board with the RS232 adapter on your computer’s end

  • Connect the ETH0 port of the base board with a network with the help of the Ethernet cable
