Fig. 3.3 Front Panel Power Supply onnections
POWER -
Eight pin connector for connecting the unit to a regulated DC power supply
of the rating detailed in Section 3.3.2.
Thorlabs offers a compact power supply unit (TPS002), allowing up to two Driver K-
Cubes to be powered from a single mains outlet.
USB
- USB port for system communications.
ON
- Power ON/Standby switch. When in the ON position, the unit is fully powered
up. When the switch is turned to the Standby position, the unit initiates a controlled
power down sequence, saving all user-adjustable parameters to non-volatile memory
before turning off the power. For the first few seconds, the shutdown can be cancelled
by turning the switch on again, in which case the unit will save the parameters but will
remain powered up. In a powered down (Standby) state, the logic circuits are
powered off and the unit will draw only a small quiescent current. The switch should
always be used to power down the unit.
TRIG 1 and TRIG 2
- SMA connectors for use with external trigger input and output
signals (5V TTL levels). The function is set to trigger IN or OUT via the settings panel
- see Section 6.2.4..
Shock Warning
The unit must be connected only to a DC supply as detailed in Section
3.3.2. Connection to a supply of a different rating may cause damage to
the unit and could result in injury to the operator
Note
The USB cable length should be no more than 3 metres unless a powered
USB hub is being used.
