Ethernet Connection
• When used as an output, typically when the receiver is a
base, port P or Q may forward differential data to a server
(see $PASHS,BAS).
• Still as an output, typically when the receiver is a rover,
port P or Q may provide NMEA messages to a server (see
$PASHS,NME).
• Port P or Q can also be used as an input for differential
data (see $PASHS,CPD,REM). This may be typically the
case when the receiver is used as a rover.
Here are a few key instructions to understand how to use port
P or Q through an IP connection:
• Port P or Q can only be used in client mode, using the TCP
or UDP protocol.
• Use the $PASHS,NTR,PAR command to implement the
NTRIP mode through port P or Q.
• Use the $PASHS,DIP command to implement the Direct
IP mode through port P or Q.
• Using the Web Server is the easiest way to set up port P or
Q.
Differential Data
Streaming Through
Ports
I1 to I9
The Ethernet port can also be used through ports I1 to I9 (Ix)
to output differential data streams for use either in server or
client mode. Ports I1 to I9 can only be used as outputs.
Here are a few key instructions to configure ports I1 to I9:
• Use $PASHS,DST to configure each port (server/client,
UDP/TCP, IP port number).
• Use $PASHS,BDS to define the differential data available
on each port.
• Use $PASHQ,DST,STS to read the current status of each
of the Ix ports. This command also provides information
on the status of ports E, P and I.
• In server mode, each port can up to five connections.
• Access to each of these ports is not password protected.
• Using the Web Server is the easiest way to set up ports I1
to I9.
Log Files
The history of Ethernet connections and disconnections is
kept in a log file stored in the root directory of the internal
memory.
This file is kept in memory for a user-set period of time (see
$PASHS,LOG,PAR). A new log file is created every day.
The naming convention used for log files is: “yyyymmdd.log”
where yyyy is the year, mm is the month number (1-12) and
