Quad Temperature Controller Command Set

List of commands for the ICE Quad Temperate Controller.

TempSet?

Arguments:

No Arguments Taken

Example:

TempSet?  

I2C Command Number:


Description

Returns the temperature setpoint for channel CHANNEL.

Example:

TempSet 3 24.55 
24.548

I2C Command Number: 17


Description

Sets the temperature setpoint for channel Channel to TEMP. Returns output from TempSet?.

Note: temperature setpoint cannot be set outside of the bounds of the minimum and maximum temperature. If TEMP is outside that range, temperature setpoint will not be adjusted.

Arguments:

No Arguments Taken

Example:

BiPolar?  

I2C Command Number:


Description

Returns whether the temperature loop for channel CHANNEL is bipolar.

Arguments:

[Int] CHANNEL
[ASCII] On/Off

Example:

BiPolar 3 Off 
Off

I2C Command Number: 19


Description

Sets the temperature loop for channel CHANNEL bipolar (heating only) on or off. Turn Bipolar off when driving resistive heaters. Returns output from BiPolar?.

Servo?

Arguments:

No Arguments Taken

Example:

Servo?  

I2C Command Number:


Description

Returns the status (ON or OFF or FAULT) of the temperature servo loop for channel CHANNEL. A return of fault means that the temperature is outside the min/max temperature range and that the temperature loop has been temporarily disabled.

Servo

Arguments:

[Int] CHANNEL
[ASCII] On/Off

Example:

Servo 3 On 
On

I2C Command Number: 21


Description

Turns the temperature servo loop for channel CHANNEL on or off. Returns the output of Servo?

Current?

Arguments:

No Arguments Taken

Example:

TempMin?

Arguments:

No Arguments Taken

Example:

TempMin?  

I2C Command Number:


Description

Returns the minimum temperature for channel CHANNEL. If the temperature is ever less than MINTEMP, the board will temporarily disable the temperature loop until the temperature rises above MINTEMP. <html></div></html>

TempMin

Arguments:

[Int] CHANNEL
[Float] MINTEMP

Example:

TempMin 3 14.32 
14.3

I2C Command Number: 26


Description

Sets the minimum temperature channel CHANNEL to MINTEMP. Returns TempMin?. Note: You cannot set MINTEMP greater than the temperature setpoint. Attempting to do so will not change the minimum temperature. <html></div></html>

TempMax?

Arguments:

No Arguments Taken

Example:

TempMax?  

I2C Command Number:


Description

Returns the maximum temperature for channel CHANNEL. If the temperature is ever greater than MAXTEMP, the board will temporarily disable the temperature loop until the temperature drops below MAXTEMP. <html></div></html>

TempMax

Arguments:

[Int] CHANNEL
[Float] MAXTEMP

Example:

TempMax 3 54.32 
54.3

I2C Command Number: 28


Description

Sets the maximum temperature channel CHANNEL to MAXTEMP. Returns TempMax?. Note: You cannot set MAXTEMP less than the temperature setpoint. Attempting to do so will not change the maximum temperature. <html></div></html>

Gain?

Arguments:

No Arguments Taken

Example:

Gain?  

I2C Command Number:


Description

Returns the gain setting temperature loop servo gain for channel CHANNEL. Gain can be from 1 to 255. <html></div></html>

Gain

Arguments:

[Int] CHANNEL
[Int] GAIN

Example:

Gain 3 34 
34

I2C Command Number: 30


Description

Sets the gain for the temperature loop servo gain for channel CHANNEL. Gain range can be 1 to 255. Returns output of Gain?. <html></div></html>

RecData

Arguments:

RecStat?

Arguments:

No Arguments Taken

Example:

RecStat?  

I2C Command Number:


Description

Returns the status of recording data from the RecData command. Returns status of either NODATA, BUSY, FINISHED. <html></div></html>

RecInt?

Arguments:

No Arguments Taken

Example:

RecInt?  

I2C Command Number:


Description

Returns the setting for the time interval between data points when taking data with the RecData command. Time between points is 10ms * INTERVAL. Value can be from 1 to 255 (10ms – 2.55s) <html></div></html>

RecInt

Arguments:

[Int] INTERVAL

Example:

RecInt 200 
200

I2C Command Number: 34


Description

Sets the interval setting for time between data points when taking data with the RecData command. Time between points is 10mS * INTERVAL. Value can be from 1 to 255 (10ms – 2.55s). Returns output of RecInt? Command. <html></div></html>

RecAmp?

Arguments:

No Arguments Taken

Example:

RecAmp?  

I2C Command Number:


Description

Returns the amplitude for data stored by the RecData command. Valid range is 0-5. When AMPLITUDE is 0, the range for the temperature error is from -18.75mK to 18.75mK in steps of 0.15mK. When AMPLITUDE is 1, the range for the temperature error is from -37.5mK to 37.5mK in steps of 0.3mK. When AMPLITUDE is 5, the range for the temperature error is from -600mK to 600mK in steps of 4.7mK.
The formula for the temperature range is +/-18.75mK*2^(AMPLITUDE) in steps of 0.15mK*2^(AMPLITUDE). <html></div></html>
