Astroda: -------- If you try to bin (decimate, really) the scrolling display by 16, you get the following error. Note, however, that a bias drift did appear to be properly decimated in spite of the error message. can't set "scd_id6_bin": {id6 { Specified value out of range}} while executing ".scd.displays.inodes.id6.bin.menu invoke active" ("uplevel" body line 1) invoked from within "uplevel #0 [list $w invoke active]" invoked from within "if {[$w type active] == "cascade"} { $w postcascade active set menu [$w entrycget active -menu] tkMenuFirstEntry $menu } elseif {[$w type activ ..."

I issued a new track command without stopping the axes first, and saw this failure: track 121,30 mount 0 5 > Started; Cmd='track 121,30 mount' 0 5 W Text="some axes will not be slewed"; AxisNoSlew="FFT" 0 0 F Modu="prt_ReadReplySet"; Text="too many replies on port LTA19:" 0 0 I Modu="prt_ReadReplySet"; Text="the following replies were read:" 0 0 I Modu="prt_ReadReplySet"; Text="ERR: I don't have the semCmdPort semaphore" 0 0 F Modu="prt_ReadReplySet"; Text="too many replies on port LTA19:" 0 0 I Modu="prt_ReadReplySet"; Text="the following replies were read:" 0 0 I Modu="prt_ReadReplySet"; Text="ERR: I don't have the semCmdPort semaphore" 0 0 F Modu="prt_ReadReplySet"; Text="too many replies on port LTA19:" 0 0 I Modu="prt_ReadReplySet"; Text="the following replies were read:" 0 0 I Modu="prt_ReadReplySet"; Text="ERR: I don't have the semCmdPort semaphore" 0 0 F Modu="axe_o_NoAbsRefCorr"; Text="could not disable absolute encoder correction for AZ , ALT, ROT" 0 0 W AxisNoTrack="TTT" 0 0 I AxisStop="TTT" 0 5 F Text="move failed; axes halted" 0 0 I TCCStatus="HHH","NNN"; TCCPos=NaN,NaN,NaN; AxePos=53.97,69.17,46.31 0 0 W AzStat=53.968785, 150.409043, 4504241709.31959, 0x40000000; WarnAzStatus; AzDTime=-0.1 0 0 I ObjNetPos = 121.000000, 0.000000, 4504241716.44429, 30.000000, 0.000000, 4504241716.44429 0 0 I ObjInstAng = NaN, NaN, NaN 0 0 I SpiderInstAng = NaN, NaN, NaN 0 0 I Modu="exe_BrdTelPos"; Text="381800 packets sent successfully" 0 0 I Modu="exe_BrdTelPos"; Text="381850 packets sent successfully" 0 0 I Modu="exe_BrdTelPos"; Text="381900 packets sent successfully" an axis init, followed by another track command worked fine.
