Rev4 rear panel layout.
From left to right, the features of the rear panel (Figure 2.4) are:
Power switch
Switches the unit on/off.
DC supply
2.1mm centre-positive barrel-jack connector for supplying power the
unit.
Not required if power is supplied over USB. Use of a floating
(unearthed) plugpack power supply is not recommended.
Use +5 V
for Rev1 to Rev3; +9 to +30 V for Rev4 devices.
USB
Standard USB type-B connector for powering and/or communicating
with the device. When used to power the device, must be connected
to a USB port capable of supplying 600 mA.
Ethernet
RJ-45

TRIG
Active-low TTL input for synchronising the wavemeter measurement
to an external trigger (see §4.5).
FSW
