Protocol
Mode
Choose one of the following:
•
Telnet:
User names, passwords, and data are transmitted without
encryption.
•
Secure SHell (SSH), version 1:
User names, passwords, and data are
transmitted in encrypted form. There is little or no delay when you are
logging on.
•
Secure SHell (SSH), version 2:
User names, passwords, and data are
transmitted in encrypted form, but with somewhat more protection than
version 1 from attempts to intercept, forge, or alter data during data
transmission. There is a noticeable delay when you are logging on to
the Battery Management System.
•
Secure SHell (SSH), versions 1 and 2
: Do not enable both versions of
SSH unless you require that both be activated at the same time.
(Security protocols use extensive processing power.)
