6. Configuring the RF-7800W
6.1. Command Mode Overview
The Ethernet port on the unit is used to send and receive data over the air, as well as to
configure the RF modem.
The user interacts with the radio via a TCP/IP telnet session, connecting to a
preconfigured IP port (the factory default is port 23). The behavior of any given connected
telnet session depends on the credentials entered during the authentication challenge at
the start of the session.
If the ADMIN role credentials are entered, the corresponding telnet session will be in
Command Mode. The
RF-7800W
may then be programmed and/or configured.
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.
6.2. Setting a Parameter
RF-7800W
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
RF-7800W
modem to 1234,
enter the following command:
ATDT 1234
<
CR
>.
RF-7800W
radios automatically save changed parameters to non-volatile EEPROM
memory whenever the parameter value is changed.
6.3. 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
RF-7800W
’s
destination address
and its address was 1234, the user would issue the following command:
ATDT
<
CR
>
and the modem will respond with:
