 +=== Connection to Laser Diode ===
 The SLICE-DCC requires that the cathode of the laser diode is at ground (<imgref cath_gnd>).  The anode is connected to the center conductor of the SMA connector on the rear of the SLICE-DCC and the cathode is connected to the sheath. The SLICE-DCC requires that the cathode of the laser diode is at ground (<imgref cath_gnd>).  The anode is connected to the center conductor of the SMA connector on the rear of the SLICE-DCC and the cathode is connected to the sheath.

 +=== Connection to Monitor Photodiode ===
 +Either of the two configurations of the monitor photodiode seen in <imgref mon_pd> will work for the signal proportional to the laser diode power for operating in Constant Power mode.  Depending on how you have completed the monitor photodiode circuit, you may have to adjust the [[slice:dcc#constant_power_mode|sign of the Constant Power feedback loop]].

 ==== Setting the Operation Mode ==== ==== Setting the Operation Mode ====
 The SLICE-DCC has two operation modes: Constant Current and Constant Power.  The operation mode, as with most other operating parameters can be set independently for each channel.  To toggle between Constant Current and Constant Power modes, from the Home screen, touch the window labelled either CH X Constant Current or CH X Constant Power.  If the channel is in Constant Current Mode, you will be presented with the window seen in <imgref cc_param>. \\ The SLICE-DCC has two operation modes: Constant Current and Constant Power.  The operation mode, as with most other operating parameters can be set independently for each channel.  To toggle between Constant Current and Constant Power modes, from the Home screen, touch the window labelled either CH X Constant Current or CH X Constant Power.  If the channel is in Constant Current Mode, you will be presented with the window seen in <imgref cc_param>. \\

-On the rear panel of the SLICE-DCC is an SMA input for servoing or modulating the current output.  (<imgref back>, item 9).  The transfer function for this input depends on the current capacity (see <tabref specs>).  The input range is ±10 V.  The current can be modulated over the full range of current except for the 2,000 mA model which can only swing ±500 mA.  The 3-dB bandwidth of this modulation input is DC to 1 MHz.+On the rear panel of the SLICE-DCC is an SMA input for servoing or modulating the current output.  (<imgref back>, item 9).  The transfer function for this input depends on the current capacity (see <tabref specs>).  The input range is ±10 V.  The current can be modulated over the full range of current except for the 2,000 mA model which can only swing ±50 mA.  The 3-dB bandwidth of this modulation input is DC to 1 MHz.
  
 It is also possible to introduce a modulation/control signal from the front-panel input BNC.  Only one input port can be active at a time. It is also possible to introduce a modulation/control signal from the front-panel input BNC.  Only one input port can be active at a time.

 +=== Hardware Temperature Exceeded ===
 +Displayed when hardware temperature exceeds a safe limit for an individual channel. Turn off the SLICE-DCC and let the unit cool for several minutes. If problem persists, contact Vescent.

 +=== Interlock === 
 +Displayed on both channels when the interlock circuit is open. Double check that the Interlock Key is inserted and in the "Closed" position, and that the Interlock BNC port is connected to either an interlock system, or the 50Ω terminator cap.
