If the USER role credentials are entered, the corresponding telnet session will also be in
Command Mode as above; however, in this case, the radio cannot be programmed or
configured. The user can execute certain commands to read settings. Section 5.7 list
the commands, and which ones are available to the user session.
If the DATA role credentials are entered, the corresponding telnet session will be in data
Communication Mode. In this case, data entering the device via the telnet session is
transmitted over the air. Data received from another RF modem is output to the user via
the telnet connection.
The following descriptions detail the Command Mode modem behavior.
5.2.
Resetting the IP Address
For the first 30 seconds, the unit listens to the default IP address. (192.168.26.4 port 23).
If someone logs into the default IP address, the unit will reset the user settings back to
default.
5.3.
Setting a Parameter
RV-M29
modem parameters may be set via any ADMIN telnet session. To do so, enter
the proper command, a space, the corresponding parameter, and then a carriage return.
For example, to set the destination address of the
RV-M29
modem to 1234, enter the
following command:
ATDT 1234
<
CR
>.
RV-M29
radios automatically save changed parameters to non-volatile EEPROM memory
whenever the parameter value is changed.
5.4.
Reading a Parameter
To read the value of a particular setting, issue the command with no parameter via either
an ADMIN or USER telnet session. The modem will return the value followed by an
“OK”.
For example, if the user enters the command to read the
RV-M29
’s
destination address
and its address was 1234, the user would issue the following command:
ATDT
<
CR
>
and the modem will respond with:
1234
<
CR
><
LF
>
OK
<
CR
><
LF
>
To get on-line help with a command, enter the command and put a question mark in for
the parameter. For example, to see what the ATDT command is used for, type
ATDT ?
<
CR
>. The modem will respond by listing a brief description of the command. To see a
list of all commands, type
HELP
<
CR
>.
5.5.
CONFIG Button
If certain parameters within the
RV-M29
transponder are modified in a manner that
erroneously causes the modem to cease functioning or if the user cannot enter Command
Mode via an ADMIN telnet session, there is a small push-button internal to the
RV-M29
to
