-<function=ICEfunc|0=BiPolar&1=I:CHANNEL:3;A:On/Off:Off&2=Off&3=19> +The Quad Temperature Controller Board (ICE-QT1) provides 4 independent PID temperature servo loops capable of sub-mK stability.((The ICE-QT1 has non-adjustable poles.  They have been set appropriately for Vescent D2-100 DBR lasers and for Photodigm Mercury lasers. /* Sub-mK stability requires a proper thermal design and proper tuning of the temperature controller to the thermal plant. If you did not purchase the Laser Controller with a Laser Diode, please read the section on tuning the temperature controller. */)) Each channel can drive either a single TEC (bipolar current output) or resistive heater (unipolar current output) and read a single 10k thermistor.

The pin diagram for the top flat flex connector (J2) is shown below and the bottom connector (J5) has the same pin definition for channels 3 & 4. Pin 1 is defined the same as noted in the datasheet for the [[http://portal.fciconnect.com/Comergent//fci/drawing/sfw12lf.pdf|SFW12R FFC connector]] and shown below in <imgref FFCpindef>. Rth and Rth_Rtn are the two ends of a 10k thermistor. The polarity for the TEC connections uses the assumption that current is flowing from the positive terminal to the negative, the TEC is heating.

 +The flat flex jumper cables used to connect to the FFC connectors should be 1.00mm pitch with 12 conductors. Another FFC connector must be used on the other side to break out the connections for OEM use. It should be noted that when connecting to the other side of the FFC, all the pin definitions will be reversed (i.e. pin 1 on one side will be pin 12 on the other). 
  
 +<WRAP center round info 60%>
 +Generally with flat flex jumper cables, the cables can be folded but the bend radius should not be less that 2mm. The clearance in front of the pcb FFC connectors must be at least 0.25 inches to allow the flat flex cable to exit and bend. The distance between the FFC connector and the first bend of the flat flex cable is determined by the length of the stiffener (or backing) on the flat flex cable.

 +===== Quick Start Commands Guide =====
 +
 +Please see [[ice:commands:overview|Overview of Commands and Basic Usage]], [[ice:commands:common|Common Commands to all Slave Boards]] and [[ice:commands:quadtemp|Quad Temperature Controller Commands]] for a complete command list. Set the ICE-MC1 to communicate with the slot that this ICE-QT1 is in (see [[ice:master#quick_start_commands_guide|Master and Control Board Overview]] for details).
 +
 +The ICE-QT1 has 4 channels of temperature control. Also all commands take the channel number (1-4) as the first argument. To read the temperature setpoint for channel 2, send the command
 +
 +  TempSet? 2
 +  25.0
 +  
 +To change the temperature setpoint, the first agrument is the channel number (1-4) and the second is the desired temperature setpoint. The command will return the actual setpoint, which maybe be different than input setpoint because of the quantization of the available temperature setpoints. For example:
 +
 +  TempSet 2 23.77
 +  23.8
 +  
 +When driving a TEC, the ICE-TM1 should be configured to be in bipolar mode. When driving a resistive heater, turn off bipolar mode. This can be done with the **BiPolar** command
 +
 +  BiPolar 3 On
 +  On
 +  
 +  BiPolar 4 Off
 +  Off
 +  
 +
 +The temperature min and max values can be set with the **TempMin** and **TempMax** commands. When the temperature is outside of this range, current to the TEC or resistive heater is turned off. Units are °C
 +
 +  TempMin 3 16
 +  16
 +  
 +  TempMax 3 40
 +  40
 +  
 +  
 +  
 +The temperature servo loop can be turned on or off the the **Servo** command:
 +
 +  Servo 2 On
 +  On
 +  
 +  Servo 2 Off
 +  Off
 +  
 +The temperature can be read with the **Temp?** command:
 +
 +  Temp? 3
 +  24.56
 +  
 +When the temperature is near the temperature setpoint (within 300mK) the **TError?** command can read the temperature error (T<sub>setpoint</sub> – T<sub>actual</sub>), in units of °C.
 +
 +  TError? 4
 +  0.021
 +
 +The gain of the temperature loop is set with the **Gain** command and has a range of 1-255.
 +
 +  Gain 1 56
 +  56
 +  
 +Once the right values are set on the ICE-QT1, use the **Save** command to save the current settings so that the settings will be remembered when the device is power cycled. Please note that the temperature loop always starts off and must be turned on the the **Servo** command
 +
 +  Save
 +  Success
