Starting the Wayside Chandra ACA EGSE

1. Log in to cooty or unagy as user aca.
2. Start the telemetry receipt process:

   ssh aca@cooty
   egse    # Set environment for running EGSE 
   kill_recv_tlm   # Typically not required but a good idea
   start_recv_tlm >>& recv_tlm.log &
   tail -f recv_tlm.log
   

3. Confirm proper startup

   START_RECV_TLM% Initializing for SKA, defaulting to world write
   permission
   START_RECV_TLM% cd
   /acawayside/ska3/data/aca_egse/tlm/raw_cooty.cfa.harvard.edu
   Starting recv_tlm and memshar_put at  2019 Mar 26 (085) 17:38:29 UTC
   % /acawayside/ska3/share/aca_egse/recv_tlm.pl:  2019 Mar 26 (085)
   17:38:29 UTC: Opening socket to listen on port 5019, timeout 3600
   % /acawayside/ska3/share/aca_egse/recv_tlm.pl:  2019 Mar 26 (085)

   % /acawayside/ska3/share/aca_egse/recv_tlm.pl:  2019 Mar 26 (085)
   17:38:29 UTC: New socket accepted
   

4. If the socket is not accepted or other issue, call up GOT Duty officer or IST (or telephone: 6-7069 or 617-592-6010) and ask them to recycle the connection to cooty or unagy. You should see the telemetry receipt program confirm that a connection has been made.
5. Run ACA image display tool splat.pl from another window

   ssh aca@cooty
   egse   
   memshar_get.pl | splat.pl
   

Starting the Backup Chandra ACA EGSE

1. Contact HEAD systems personnel and ask that they switch the ACA home directory server to numa with this procedure if needed.
2. Log in to kadi-test as user aca.
3. Start the telemetry receipt process:

   ssh aca@kadi-test
   egse    # Set environment for running EGSE (not necessary on coot)
   kill_recv_tlm   # Typically not required but a good idea
   start_recv_tlm >>& recv_tlm.log &
   tail -f recv_tlm.log
   

4. Confirm proper startup

   START_RECV_TLM% Initializing for SKA, defaulting to world write permission
   START_RECV_TLM% cd /proj/telmon/tlm/raw
   Starting recv_tlm and memshar_put at  2009 Jan 21 (021) 18:51:54 GMT

   % /proj/telmon/aca/bin/recv_tlm.pl:  2009 Jan 21 (021) 18:51:57 GMT: Waiting to accept socket connection on port 5019
   % /proj/telmon/aca/bin/recv_tlm.pl:  2009 Jan 21 (021) 18:51:57 GMT: New socket accepted
   

5. Run ACA image display tool splat.pl from another window

   ssh aca@kadi-test
   egse   
   memshar_get.pl | splat.pl
   

Additional info

• Other engineering telemetry can be displayed similarly by typing disp <DISP_PAGE> where the list of <DISP_PAGE>'s can be found in /home/aca/disp_pages.
• The ACA EGSE software is found in /proj/telmon/aca, with the scripts/executables within the bin directory.
