sudo service ovms-svc stop/start
ovmsMonitor.cfgfile (in /lbt/ovms/current/etc/) tells the applications running on the ovms Linux box which slot/channel is which accelerometer. This file is used by the ovms monitor GUI as well as telemetry. This file does not influence the multicast data.
config.txtfile on the
ovms-ueimachine tells the OVMSplus prediction software which channels to use in the calculations.
sensitivities.txtfile on the
ovms-ueimachine tells the OVMSplus prediction software which gain factors to use in the calculations for particular focal station geometries (specified with the -P command line argument). Beware that focal station geometries are not applied in Mode 3 (see IT 7486).
sudo /etc/init.d/ovms-svc [start|stop|restart|status](why does it have to be root?) The data is always broadcast by the OVMS application (for use by clients such as the
ovmsMonitor). When the
ovmsTelemetryservice is running, telemetry collection can be run or paused using the
ovmsTelemetryClient. Typically the service is left running and there is a cron job which pauses and resumes the collection using the
ovmsTelemetryClientso that it only runs at night (0:00 UT to 14:00 UT; 5:00 pm - 7:00 am local time).

I ran a test of the OVMS telemetry collection at 500Hz. This applies only to the HDF5 telemetry collection, not the real-time broadcast data. The OVMS telemetry collection frequencey defaults to the minimum rate in the configuration file. A config file change, and a bounce of the telemetry daemon will make it run at the lower rate. I tested it today, but put the configuration back to minimum 1KHz after my test. To default to 500Hz: 1. pause telemetry and stop the daemon - ovmsTelemetryClient -x 2. change the file /lbt/ovms/current/etc/ovmsTelConfig.cfg TelService.Sample.MinFreq=1000 to 500 3. restart the daemon - sudo service ovms-svc start 4. restart telemetry collection - ovmsTelemetryClient -r

|Sep-2017||IT6759||Phil, SX - but data looked bad on DX_M2, but all channels were reading incorrectly from slots 7 and 8|
|31-Aug-2017||IT6735|| All the data from racktangle cards 7 and 8 are railed at +-25V.
That means that DX M2 is not contributing anything to the OVMS+ predictions (4 of its 5 accelerometers read zero).
|IT6736||The OVMS+ SX Tip-Tilt prediction is full of noise. However, the only SX accelerometer channel that is obviously noisy is what telemetry calls SX_M3_3 which should be card 3 slot 2 (but it's configured to read slot 3, channel 1 which has nothing plugged in to it). The other four SX_M3 channels are OK. The channel that telemetry calls SX_M3_5 looks normal even though that cable isn't plugged in (because it's reading slot 3, channel 2 which was labeled M3-3).|
|30-Mar-2017||IT6496||swapped the slots of DX_M2_3 and DX_M2_2 because racktangle card 8 slot 3 was bad.|
|14-Apr-2016||IT5943|| card 3 slot 1 was bad (why nothing is plugged in to it now).
SX_M3_5 is hanging, SX_M3_3 is slot 3, channel 2
|Mar-2016||IT5911||swapped DX M2 2 and 3|
|Mar-2016||IT5912||slot 7 bad|
|Dec-2014||IT5423||slot 3, channels 1 and 2 red, tightened|
