This morning I built labview foucs/alignment to only talk to Rcam/cam0 based on our existing focus.vi. On the first pass I missed commenting out one set exposure call on cam1. The alignment code crashed and I incorrectly assumed and I found myself in a configuration where I could no longer talk to cam0 with pfremote. (In hindsight this was becasue labview still and open refence to the camera blocking pfremote for getting access ot the hardware). Thinking the issue was hardware related I did a repeat of the inspections Allen did Saturday. Control room camera links seemed fine. Soild Green Leds on the front Blinking red leds on the back Up stairs the camrea link extenders both looked fine green LEDs. Rcam status had a red LED Tcam status no led On power cycling of the upstairs equpiment (camera and cameralink) I was able to reconnect to Rcam with pfremote. Tcam was still offline. Just to make sure we didtn have a cableing issue: Power cables were swapped between the two cameras at the cameeras. We could connect to cam0 and not cam1. Note I moved Rcam focus; the knurled focus knob felt like the knurled thumb screw around the power cable. Next swapped the extender->camrea cameralink cables. Now Rcam was talking to pfremote on the cam0 port; tcam still down on the cam1 port. Extneders swapped back. Conclusion1: TCAM 13890 appears to be dead At this point I looked back into the labview code and found and commented out the code where I was trying to talk to Tcam/cam1. This fixed the crashing and I can now connect and disconnect from the cam0 with labview or pfremote at will. Next socketcam: socketcam source was edited to comment out calls to cam1. This was a bit of a hatched job but after a couple trial runs it appears to be working with 1 camera. Fits files are the same size as before with coronal data in the cam0/tcam half of the data file and 0's in the cam1/rcam half. The new socketcam is called socketcam-cam0.exe and that name should appear in the fits header under the keyword socketcam. The TCAMID keyword has been hardcoded to 13890, Rcam still asks the carmea for its ID. With the diffuser in the Rcam was refoucsed on the sun. This appears to be a pretty good focus; but we will need to run another distorition test to be sure. Holding off on that until the replacement camera arrives from Boulder. ___end___ Mon Mar 04 21:48:37 GMT 2019 Kcor Focus/alignment program exited GENERAL COMMENT BY berkey: Tue Mar 05 02:58:23 GMT 2019 No data today. ___end___ ONSITE STAFF: berkey
