Hello,

I have an hpi 6032 Digital Area Monitor, which only provides 1-way communication. The device sends out a packet of ata
Every second that should look like this:

                      000001 0064 0000 0032 00 00
The data from left to right is read as 6-groups of hex digits.
The profile looks as follows:

Terminator  = CR LF;
RReadTimeout = 200;
ReplyTimeout = 800;
PollPeriod = 800;

read {
  in                                                                   # only 1-way communication
  "%(A)x"                                                       # gamma dose rate
  "%(\$1GammaTripLevel.A)x"            # high trip level
  "%(\$1GammaTripLowLevel.A)x"    # low trip level
  "%(\$1GammaFailCounter.A)x"        # fail count down
  "%(\$1GammaDoseStatus.A)x"         # status byte
  "%(\$1GammaHVStatus.A)x";           # second status byte
}
The first data (left most hex digit) I can read, the others pvs' don't process.  I copied a profile from elsewhere that used this device, and the read was setup the same
With the exception only the 1st 3rd and 6th data elements were read (from left to right), so a "%*x" was used to skip those data points.  However, the file was for a different model
And still only the 1st data point was processed in the db. I have been able to read the 1st and 2nd data points, but the rest won't follow, so I must be doing something wrong in the db or the profile. 

I  know the device is working because if I connect up a serial port to my laptop and view the data, it looks fine.    Are there any suggestions as I am fairly new to using stream device.

Regards,
  Kristi

  field(CALC, "A&1?1:0")
  field(FLNK,  "$(BL)GammaGammaAlarmSeverity")
}

I've also tried setting each record with SCAN Intr I/O and the  OUT field the command in the profile and only the readRate works, which is the first hex ditgit, the others pvs never process.
readRate     { in "%(A)x %*x %*x %*x %*x %*x"; }
readTrip     { in "%*x %(A)x %*x %*x %*x %*x"; }
readTripLL   { in "%*x %*x %(A)x %*x %*x %*x"; }
readFailCnt  { in "%*x %*x %*x %(A)x %*x %*x"; }
readStat     { in "%*x %*x %*x %*x %(A)x %*x;" }
readHVStat   { in "%*x %*x %*x %*x %*x %(A)x;" }

debug {
  ExtraInput = Ignore;
  in "%39c";
}
