### Connecting to the Pingvin unit
|
||||||
|
- Connect an RS-485 adapter to the computer you intend to run the daemon on
|
||||||
|
- Tested only on a RPi 4B and Zero W 1 with the Zihatec RS-485 HAT
|
||||||
|
- You may need terminating resistors in your adapter, see documentation
|
||||||
|
- Ensure the user has read/write privileges to the serial device.
|
||||||
|
- No need to run the daemon as root, and it is not recommended
|

|
||||||
|
- Open the cover in which the power switch is attached to. No need to disconnect the switch, there
|
||||||
|
should be enough length in the wires to move the lid with the switch connected out of the way

||||||
|
- Locate the green RS-485 connector on the motherboard
