Detailed Description

AzCam Server CCD Temperature Control Functions.

The following are a suite of interface functions that provide access to all of the AzCam server temperature control commands.

All routines call the communication layer routines in iosubs.c to take care of common handling of timeout, errors, and reply processing.

All of the server temperature control commands documented in Section 10 of the AzCam Programmers Reference Manual have been implemented except the following:

  ReadTemperature - GetTemp fulfilled the same basic function
  

SetTemperature has been shortened to SetTemp to match the pattern set by GetTemp and SetTempCal.

Function Documentation

int GetTemp (  azcam_t *  cam, char *  reply )

Get the Detector and Dewar temperatures. Parameters: cam  pointer to an azcam struct with the server parameters reply  string to contain any reply text Returns: 0 if successful, -1 on errors, with error text in reply. Temperature values are in azcam::CCDTemp and azcam::DewarTemp. Queries the AzCam server and readout out the detector and dewar temperatures in degrees C, storing the results in the azcam::CCDTemp and azcam::DewarTemp data members. See also: SetTemp(), SetTempCal()

int SetTemp (  azcam_t *  cam, float  temp, char *  reply )

Set the CCD temperature set point. Parameters: cam  pointer to an azcam struct with the server parameters temp  CCD detector set point in degrees Celsius reply  string to contain any reply text Returns: 0 if successful, -1 on errors, with error text in reply Sets the target detector temperature setpoint in degrees C. Temperatures may be given to the nearest 0.1C. The new setpoint temperature is stored in azcam::SetPoint data member for use by the application. SetTemp implements the SetTemperature server command. The name was shortened to match the syntax of the related GetTemp and SetTempCal server commands. See also: GetTemp(), SetTempCal()

int SetTempCal (  azcam_t *  cam, int  diode, int  detector, int  dewar, char *  reply )

Set the calibration curves used for each temperature sensor. Parameters: cam  pointer to an azcam struct with the server parameters diode  sensor type of the diode detector  sensor type of the detector temperature sensor dewar  sensor type of the dewar temperature reply  string to contain any reply text Returns: 0 if successful, -1 on errors, with error text in reply Sets the calibration curves to be used by each of the temperature sensors monitored by the AzCam server. There are three types of temperature calibration curves available, depending on the type of sensor used: DT670 - DT670 diode AD590 - AD590 sensor N914 - 1N914 diode Note that there is an oddity about C in that parameters defined as "macros" with #define statements apparently cannot begin with numbers, which is why for the 1N914 diode we use N914 not 1N914 as the value passed to the subroutine. Go figure. See also: GetTemp(), SetTemp()
