About Certificates; Load A Certificate - Honeywell CN75 User Manual

Honeywell recommends WPA2 security with PSK (Personal) or 802.1x (Enterprise)
key management.
Before you set security, you need to enable the radio, set the date, and set the SSID
on your computer. To use 802.1x security, you need to load a root certificate on
your computer. To use transport layer security (TLS) with 802.1x security, you also
need to load a user certificate.

About Certificates

You can use digital certificates to identify the computer for network access or
authentication to servers. To use a certificate to identify your device, you must
install it in the trusted credential storage on the computer.
Android supports DER-encoded X.509 certificates saved in files with a .crt or .cer
file extension. To install a valid certificate with a .der or other extension, you must
change the extension to .crt or .cer to install it.
Android also supports X.509 certificates saved in PKCS#12 key store files with a
.p12 or .pfx extension. To install a valid key store file with another extension, you
must change the extension to .p12 or .pfx to install it. When you install a certificate
from a PKCS#12 key store, Android also installs any accompanying private key or
certificate authority certificates.
