4.3 Jumper Settings

4.3.6 Node ID Switch SW1

An 8-position DIP switch is implemented, that is used to select the ARCNET Node ID of the CC121 module. The switch setting is used by the COM9026 and can be read by the MPU. The switches are numbered from 1 through 8, and each switch can be put "on" or "off". An "on"-position is read as "0", while an "off"-position is read as "1". Position 8 represent the most significant bit and position 1 the least significant bit of the 8-bit Node ID.
