RTS repo:

See RTS repo repository, that is cloned under /home/aorts/src/rts. This is configured as such in .env:

# RTS PACKAGE (g2if and consort)
export RTS_PACK_ROOT=${HOME}/src/rts
export PATH=${RTS_PACK_ROOT}/bin:${PATH}

More notes are available in The rts_start.md

Boot sequence

Run cc-rightafterboot (from computer_config repo / ${HOME}/computer_config) immediately upon login and only once.

Reminder

• Customize post-boot sequence: ${HOME}/computer_config/bin/cc-rightafterboot-thiscomputer
• Add more VNC desktops: ${HOME}/computer_config/bin/cc-vncspawn
• Customize VNC desktop startups: ${HOME}/computer_config/bin/cc-vncpopulate-<X>

If cset set yields any information, it has been run already. If it has crashed / partially run / not sure, reboot and start over.

(AO) Boot sequence - 2

Script rts_start.sh:

• Starts camera acquisition (can be achieved standalone with just cam-iiwistart)
• Starts DM write (WARNING) on loopback (not real) hardware channel
  • When ready, hop over to real DAC40: bim188-hwint hw (bim188-hwint lo back to loopback)
  • Monitor loopback DAC40 packets on SHM bim188_loopback.
• Configures AO loops.
• Start RTS/OBCP net server.

Should be run only once after the rightafterboot.

A good idea if stuff starts going wrong is to patrol the various tmuxes and check stuff around the place is still running.

WARNING

Software

Progressively porting 2021 scripts.

• Folder (on the PATH) for RTS scripts: ${HOME}/src/rts/bin
• Backup of 2021 scripts: ${HOME}/src/rts/bin_bak

Porting progressively:

• tt_zero.py [all]: reset TT command to 0V
• wtt_zero.py (0|5): set WTT to 5V (midrange, should always be there) or 0V (for power off only).
• bim_zero.py [all]: set bimorph to 0V. If [all], zeroes all channels of DMcomb00.
• tt_flat.py: loads latest ref in ${HOME}/rts/conf/tt_flats/ and shows it on DM01 channels 00.
• bim_flat.py [sim]: loads latest ref in ${HOME}/rts/conf/bim_flats/ and shows it on DM00 or DM10 channels 00.
• tt_make_flat.py:
• bim_make_flat.py [sim] [--noclear]: Gets dm00disp or dm01disp (if [sim]), saves to fits file, loads to dm0Xdisp00, clears the other channels (unless [--noclear]).

AO

See again: rts_start.md

DM units

1 DM unit = 10 V 1 TT unit = 1V 1 WTT unit = 1V

Best starting flat: -2 unit on all of BIM188.

Limits and safeties are:

• defined in ${HOME}/src/hardwaresecrets/interfaces/cw-nsl/dac40_safety.h.
• recompile cd ${HOME}/src/hardwaresecrets/interfaces/cw-nsl; ./install.sh
• Re-run (tmux fpdp_dm). Dont forget to promote cset and RT priority.
