3.3. Roles
ADMIN
The ADMIN role allows viewing and changing parameters within the unit,
but does not allow arbitrary over-the-air data transmission. Only one
ADMIN session is allowed at any given time.
USER
The USER role allows viewing parameters within the unit, and querying
GPS position information; however, unit parameter values cannot be
changed. This role does not allow arbitrary over-the-air data
transmission.
DATA
The DATA role allows exchange of arbitrary data over-the-air. This role
does not allow either viewing or changing parameters within the unit.
3.4. Login Authentication
The unit will respond to each of up to five coincident telnet connection requests with the
following authentication challenge prompt:
Login:
The client must enter the Login Name followed by a <return>. The unit will then respond
with:
Password:
The client must enter the password followed by a <return>.
Upon successful login authentication, the unit will respond with:
Prompt:
where the prompt can be set with command PROMPT XXXXXX. After three failed
attempts to enter a correct username/password combination, the session will be
terminated.
3.5. Session Modes
The
RF-7800W
‘s Ethernet interface supports different Session Modes per connection:
Command Mode and Data Mode. The mode of any given connected telnet session is
determined by the role associated with the credentials (User Name and Password) that
were entered at the session start. Sessions authenticated with either the ADMIN or USER
credentials shall operate in Command Mode, whereas session authenticated with DATA
credentials shall operate in Data Mode.
When a given
RF-7800W
telnet session is in Data Mode, it will not accept user-
commands. It will output over-the-air data or GPS information whenever the unit receives
it. Arbitrary data may also be scheduled for transmission over-the-air by simply entering it
via a telnet session operating in this mode.
