The Commands

B-3
Send Exposure Data (D)
The command for sending data acquired by an exposure is the character, D. The 4000M+ will respond to
this command by sending:
<KVEFF> <KVAVG> <MR> <TIME> <NP><CR><LF>
where:
KVEFF
is kV effective,
KVAVG
is kV average,
MR
is dose,
TIME
is exposure time,
NP
is number of kV peaks measured.
This transmission will then be followed immediately by:
<KVP1><KVP2>...<KVPN><CR><LF>
where KVP1 through KVPN are kV peaks.
The following is a sample program:
5 REM THIS CODE READS THE EXPOSURE DATA.
10 PRINT #1, “D”;
20 INPUT #1,KVEFF,KVAVG,MR,SEC,NP
FOR I=1 TO NP
40 INPUT #1, PEAK(I)
50 NEXT I
60 REM THE ARRAY, PEAK, CONTAINS KV PEAK VALUES,
70 ‘KVEFF, KVAVG, MR, AND SEC CONTAIN EFFECTIVE
80 ‘KILOVOLTAGE, AVERAGE KV, EXPOSURE, AND TIME,
90 ‘RESPECTIVELY.
Send Waveform (W)
Both channel A and channel B radiation waveforms are available through the RS-232 port. The command
is W. This puts the 4000M+ in the waveform send mode. To get 10 data points, send the 4000M+ an
integer representing the number of the first data point; terminated with a <CR>. The 4000M+ will send 10
data points, beginning at the one requested, in the format:
<CHANNEL A> <CHANNEL B><CR><LF>.
The next 10 points may then be requested by sending the index of the next point to be sent, followed by a
<CR>. When all is finished, send <ESC> (chr$(27)).
