3.3.3 RVP10 socket interface
RVP10SRV is configured to listen on a network port. It is ready to interface to a host computer
through the network using the
DspExport program. When the IRIS Radar software is
installed on the same RVP10SRV computer, it is pre-configured to communicate with
RVP10SRV processes through the native interface, bypassing the socket interface.
RVP10SRV includes built-in utilities such as Setup , dspx , and Ascope . See IRIS and RDA
Utilities Guide (M211316EN) .
Because RVP10SRV can only have one program controlling it at a time, using a local program
such as
dspx blocks network access.
3.3.4 RVP10SRV socket protocol
The socket interface supports the commands in appendix RVP10 programming interface .
All messages going both ways consist at the lowest level of an 8-character decimal ASCII
number, followed by a block of data. The decimal number indicates how many bytes follow.
Generally, all data transfers are initiated by the host computer by sending a block of data,
consisting of a command word followed by the
|
character, followed by optional data.
It responds to all commands with either an
Ack|
, indicating acknowledgment that the
command was
OK
, or
Nak|
, indicating that there was an error. For
Nak|
, the reply always
includes a string indicating what the error was. For Ack, there is optional data following.
On initial socket connection request DspExport provides a response of either
Nak|
,
indicating the connection failed and why, or
Ack|
, followed by some connection information.
The
Ack|
string is in the form of name/value pairs, for example:
Ack|CanCompress=1,Model=RVP10,Version=10.0
Your program can evaluate, or ignore, these keywords. CanCompress=1 indicates that the
DspExport computer supports compression. The host computer can then choose to use
compression. When you first connect, you are in the "info only" mode. This means that the
server only responds to INFO and OPEN commands.
DspExport supports the following commands:
• Read command (
READ
)
• Write command (
WRIT
)
• Read Status command (
STAT
)
• Set Information command (
INFO
)
• Read data available command (
RDAV
)
• Open the connection for I/O (
OPEN
)
