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.

   chewie-v has been retired and we still need to configure a machine for BUOCC

2. Log in to chewie-v as user aca.
3. Start the telemetry receipt process:

   ssh aca@chewie-v
   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) 18:51:56 GMT: Opening socket to listen on port 5019, timeout 3600
   % /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@chewie-v
   egse   
   memshar_get.pl | splat.pl
   

Start the ACA telemetry monitor by clicking the launching spaceship icon.

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.
