3.3.1 Front Panel Connections
Fig. 3.2 Front Panel
POWER -
A Standard 3.5 mm front panel jack connector for connecting the unit to a
regulated DC power supply of 15 V, 2A. See Section 1.2. for details on power supply
options.
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.
Caution
Ensure that all USB and electrical cables are positively connected and all joints
tightened. Loose connections can cause noise and interference problems due
to transients from the high switching frequencies
Warning: Risk of Electrical Shock
The unit must be connected only to a DC supply of 15V, 2A regulated.
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.
