The Open dialog box appears, letting you select the certificate file(s) to
send to the MCU.
Depending on the method used when the certificate file(s) were
created, send the certificate file(s) to the RMX according to the
contents of the file set that was created:
— The certificate files pkey.pem, cert.pem and a certPassword.txt. The
files were created by a Certificate Authority and are sent as is to
the RMX together with the required password contained in the
certPassword.txt file.
This is the recommended method.
— The files pkey.pem and cert.pem. The certificate files were created
by a Certificate Authority and are sent as is to the RMX.
— A *.pfx file and a certPassword.txt file. The file certPassword.txt is
manually created if the *.pfx file was created by the OCS using a
password. The *.pfx file will be converted internally by the RMX
using the password included in the certPassword.txt into three
certificate files named pkey.pem and cert.pem.
— A *.pfx file if the certificate file was created in the OCS without
using a password. The *.pfx file will be converted internally by
the RMX into three certificate files named pkey.pem and cert.pem.
