flashes when the corresponding channel is communicating with the external
recording device.
2: Data Output:
This 10 way connector takes the Ethernet signal from the unit to provide
data for a laptop or portable recording device. The connecting cable provided has the 10
way mating connector on the Multiplexer Box end, and a standard ethernet connector on
the other (8P8C/RJ45).
3: ON/OFF switch:
This switch turns the multiplexing box on and off. This switch has a built
in red LED to indicate the unit is powered.
4: Charge Input:
This connector is used for the external mains battery charger supplied
with the unit. See section 4.3.2. Charging for further information.
5: Status, Network and Low Power LEDs:
The
‘Status’
LED indicates that the internal “Brainbox” is enabled.
The
‘Network’
LED indicates that the system is connected to a network.
The
‘Low Power’
LED flashes when the battery is nearing the end of its charge. Battery
life remaining after this LED comes on is highly dependent on the number of gradiometers
used, so must be taken as a guide only.
6: External Power Input:
This connector allows an external battery to be connected to the
unit if the internal batteries become exhausted. This is currently under development.
Refer to the Grad-13 Operating manual OM3100 for details of how to set the Ethernet IP address
of the internal “Brainbox 8 way RS422 to Ethernet” converter. This address is initially set to the
number indicated on the label supplied with the unit but can be changed as required.
