Connection directly via USB-Serial Cable
Red Wire - Pin4 - +5V
Black Wire - Pin 6 or Pin 14 - GND
White Wire - Pin 8 - TXD
Green Wire - Pin 10 - RXD
Power directly from the Serial cable
If you are going to power the Raspberry Pi from the dedicated power adapter, DO NOT attach the +5V red wire from the serial cable.
Connect via Serial to the Raspberry Pi
In Linux, using PuTTY:
Address: /dev/ttyUSB0
Speed: 115200
Default User: pi
Default Pass: raspberry
Launch Raspberry Pi Software Configuration Tool (raspi-config)
pi@<hostname>: ~$ sudo raspi-config
Enable Networking
Option 2 - Network Options > N1 - Hostname
Please enter a hostname
raspberry-pi-zero-w
Option 2 - Network Options > N2 - Wireless LAN
Please enter SSID
<Home-SSID>
Please enter passphrase. Leave it empty if none.
<password>
Option 5 - Interfacing Options > P2 - SSH
Would you like the SSH server to be enabled?
Caution: Default and weak passwords are a security risk when SSH is enabled!
Yes
The SSH server is enabled
Ok
Option 5 - Interfacing Options > P6 - Serial
Would you like a login shell to be accessible over serial?
Yes
The serial login shell is enabled
The serial interface is enabled
Ok
Now serial and SSH are setup, the Pi Zero should be connected to the wireless network. This can be verified by exiting the Raspberry Pi Configuration Tool and checking that the hostname is set correctly and getting the IP address of the Pi Zero.
pi@<hostname>: ~$ hostname

Option 8 - Update >
The software tool will update.
Next is to update the OS.
pi@<hostname>: ~$ sudo apt update
pi@<hostname>: ~$ sudo apt upgrade
The Raspberry Pi Zero W is not configured and setup for Serial and SSH access to enable further programming and tuning.
