slsReceiver/ slsMultiReceiver

One has to start the slsReceiver before loading config file or using any receiver commands (prefix: rx_ )
For a Single Module
# default port 1954
slsReceiver

# custom port 2012
slsReceiver -t2012
For Multiple Modules
# each receiver (for each module) requires a unique tcp port (if all on same machine)

# using slsReceiver in multiple consoles
slsReceiver
slsReceiver -t1955

# slsMultiReceiver [starting port] [number of receivers]
slsMultiReceiver 2012 2

# slsMultiReceiver [starting port] [number of receivers] [print each frame header for debugging]
slsMultiReceiver 2012 2 1

Client Commands

One can remove udp_dstmac from the config file, as the slsReceiver fetches this from the udp_ip.
One can use “auto” for udp_dstip if one wants to use default ip of rx_hostname.
The first command to the receiver (rx_ commands) should be rx_hostname. The following are the different ways to establish contact.
# default receiver tcp port (1954)
rx_hostname xxx

# custom receiver port
rx_hostname xxx:1957

# custom receiver port
rx_tcpport 1954
rx_hostname xxx

# multi modules with custom ports
rx_hostname xxx:1955+xxx:1956+


# multi modules using increasing tcp ports when using multi detector command
rx_tcpport 1955
rx_hostname xxx

# or specify multi modules with custom ports on same rxr pc
0:rx_tcpport 1954
1:rx_tcpport 1955
2:rx_tcpport 1956
rx_hostname xxx

# multi modules with custom ports on different rxr pc
0:rx_tcpport 1954
0:rx_hostname xxx
1:rx_tcpport 1955
1:rx_hostname yyy
Example commands:
# to get a list of receiver commands (these dont include file commands)
sls_detector_get list | grep rx_

# some file commands are:
fwrite
foverwrite
findex
fpath
fname
fmaster
fformat

# to get help on a single commands
sls_detector_get -h rx_framescaught

Performance

Please refer to Receiver PC Tuning options and slsReceiver Tuning under Troubleshooting.

Using Callbacks

One can get a callback in the receiver for each frame to:

  • manipulate the data that will be written to file, or

  • disable file writing in slsReceiver and take care of the data for each call back

When handling callbacks, the control should be returned as soon as possible, to prevent packet loss from fifo being full.

Example

  • main cpp file

  • cmake file.

  • how to install the slsDetectorPackage with cmake is provided here.

  • compile the example e4-rxr by:

    cmake ../path/to/your/source -DCMAKE_PREFIX_PATH=/path/to/sls/install
make
