### Connecting to the Pingvin unit
|
||||
#### RPi/computer running the daemon
|
||||
- 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 of your adapter.
|
||||
- Tested on:
|
||||
- RPi 4B and Zero W 1, generic x86_64 linux machines (Alma Linux 8 & 9, Fedora)
|
||||
- Zihatec RS-485 HAT with the Pis
|
||||
- generic USB-RS485 adapter (checksum errors considerably more often, but nothing critical)
|
||||
- Ensure the user you intend to run the daemon as has read/write privileges to the serial device.
|
||||
- No need to run the daemon as root, and it is not recommended
|
||||
- **Not recommended and no need to run as root**
|
||||
- Usually adding the user running the executable to the `dialout` group gives permissions to serial devices
|
||||
|
||||
#### Pingvin
|
||||
- Shut down the main power of the unit
