Fluoroscopic Measurement (U)
The 4000M+ may be used in the Fluoroscopic Mode while under control of a host computer. The
procedure is as follows:
1. Send the character U to the 4000M+ via RS-232.
3. The 4000M+ responds with a status code; a zero (0) indicates all is ok; any other code indicates a
hardware error.
4. Once per second, thereafter, the 4000M+ sends one or two numbers, followed either by R or K and
then a carriage return/line feed.
The numbers followed by R are exposure rate, in R/min. Those followed by K are kilo voltage
values. When there is little or no exposure, only the R values will be given.
5. This output will continue indefinitely. To stop it, repeatedly send the character X until the 4000M+
responds.
NOTE
The 4000M+ does not look at the RS-232 port while
it is accumulating real-time data. Therefore, send
the X repeatedly until 4000M+ responds.
6. The 4000M+ responds by repeatedly sending 3 for a period of time, giving the computer
a chance to alternate between sending the X and looking for the response.
7. When the 3s are no longer being sent, the 4000M+ will have accumulated a final 100 ms of
waveform data. A final status code is sent. A code of 01 means all has gone well. A code of 50,
51, or 53 indicates low kVp, high kVp, or all data below radiation threshold, respectively.
8. The commands D or W may now be used to review the data.
Set Detector Sensitivity (H or L)
Set the detector sensitivity as follows:
1. Send the character H to the 4000M+ to set the sensitivity to high.
2. Send the character L to the 4000M+ to set the sensitivity to low.
The 4000M+ responds by echoing back the character sent and an 01 to indicate Ready.
