RadMonVRM202 versions
Status:
030318: The new RadMonVRM202 device (CRadMonVRM202SerialCalcDevice) (with history) is now ready.
Contents:
Overview:
This device will readout a total of 5 radiation detectors (the Veenstra Instruments VRM-202 detectors) connected through a serial link.
Device
parameters:
For addressdefinition the device uses AddTypeId number 9 (One-Dim) which uses a0 to determine which detector and parameter is addressed.
The device controls a total of 5 detectors, the reading is adressed from a0=0 to a0=4. The status bit telling whether or not the detector is active or not is adressed from a0=20 to a0=24.
Parameters (a0=0..4):
| parameter number (a0) | Suggested SirName | Parameter name | Device Type | Interpretation | Comment |
| 20..24 | ok | Detector connected | ? (status bit) | 501 | The parameter is false if no detector was found at the expected address. This may be due to an error in the connection or the detector is not connected. |
| 0..4 | reading | reading µSv/h | ? (status float) | 96 | Returns the reading of the detector in µSv/h. If the detector is not connected, the parameter is 0.0 |
Interpretations:
| Interpretation | Usage | Dataserver Id | Unit | Lover Limit | Upper Limit |
| 501 | Bit Type | 2 | |||
| 96 | Convertion Type | 1 | µSv/h | 0.000e0 | 9.999e9 |
Device
configuration:
The following parameters are stored in configuration file for the device:
- COM-Port: The serial port number.
Status:
March 2003: The old CRadiationMonitorDevice wil be taken out of operation soon, and replaced by the new device (with history)
The RadMonVRM202 device is now almost ready. The classes which talk with the controller is ready, and the framework for the device itself is ready.

Overview:
This device will control a total of 5 radiation detectors (the VRM-202 detectors) connected via a serial link.
Device
parameters:
For addressdefinition the device uses AddTypeId number 10 (Radiation Monitor) which uses a0 to determine which detector is addressed and a1 to give the parameter number.
The device controls a total of 5 detectors, numerated from a0=0 to a0=4. To numerate the two parameters pressent for each detector a1 is used.
Parameters (a0=0..4):
| parameter number (a1) | Suggested SirName | Parameter name | Device Type | Interpretation | Comment |
| 0 | ok | Detector connected | ? (status bit) | 501 | The parameter is false in detector was found at the expected address. This may be due to an error in the connection or the detector is not connected. |
| 1 | reading | reading nSv/h | ? (status float) | 96 | Returns the reading of the detector in nSv/h. If the detector is not connected, the parameter is 0.0 |
Interpretations:
| Interpretation | Usage | Dataserver Id | Unit | Lover Limit | Upper Limit |
| 501 | Bit Type | 2 | |||
| 96 | Convertion Type | 1 | nSv/h | 0.000e0 | 9.999e9 |
Device
configuration:
The following parameters are stored in registry at the frontend computer on which the device is loaded:
- COM-Port: The serial port number.
- The poll frequency of the radiation monitors measured in seconds.
