Any RF-7800W that is a TXRX may be either a PRIMARY or a SECONDARY. Primary
transmitters use TDMA slot 1 to transmit their GPS location in, and Secondary
transmitters use TDMA slot 2 to transmit their GPS locations in.
The second parameter of the MODE command is either a P or S for Primary or
Secondary. For example, to program a secondary transceiver, use the following
command:
MODE TXRX S
3.2. 10/100Base-T
– TCP/IP Socket Connections
The
RF-7800W
user interface is provided via a 10/100Base-T Ethernet interface. All user
communications in and out of the unit use TCP/IP socket connections that are compatible
with Telnet client applications. By default, the RF-7800W is a TCP/IP Telnet server.
The
RF-7800W
can interact with up to five (3) Telnet connections
(“sessions”) at any
given time
– additional connection requests beyond this limit shall be rejected (terminated
and closed) by the
RF-7800W
. By default, all connection attempts require successful
completion of a login authentication challenge sequence before an interactive session will
be established.
The “Primary IP” address that the RF-7800Wis configured to use is set
with the
IPADD
xxx.xxx.xxx.xxx
command.
There are three levels of radio modem access
or session “roles” with corresponding
privileges and features; they are:
“ADMIN”, “USER”, and “DATA”. Three programmable
User Name and Password
(“credentials”) combinations are maintained within the
RF-
7800W
, including one for each of the three roles defined above
.
The default credential
settings and their associated roles are as shown in the following table:
