Modules
The Link LED will light when the module detects that it is connected to an
Ethernet network
.
Module Operation
The following pages contain information on how to operate the NxEthernet and
NxCobraNet modules. The NexSys functions that can be controlled from the
amplifier’s rear panel will be explained. After working through this section, you should
have an understanding of the network modules’ operation through hardware. For
more on software control of the modules’ features, see the NexSys Manual.
The instructions in this section assume that a module has been mounted in the Ci
amplifier and the user has a working knowledge of the module’s control panel layout.
Making Network Connections
The Network modules are connected to the network via standard CAT-5 Ethernet
cabling using and RJ-45 connector. When the cable has been physically connected
to the module and to an active network device, the “Link” LED will illuminate.
Setting IP Addresses
Press the Function button until the LED next to I.P.Address illuminates. Once the
function has been chosen, depressing the Select button will scroll through the four
octets of the I.P. Address. The position of the decimal point in the numeric display
designates which octet has been selected. If the decimal point is to the left of all
three digits, then the first octet is being displayed. If the decimal is between the
first and second digit, the second octet is being displayed and so on. Once the
appropriate octet has been selected, press the Edit button. The octet value will
begin flashing. Press the increment and decrement buttons to change the octet
value. There are 256 possible values for each octet, ranging from 0 to 255. Once
the correct value has been reached, press the Edit button again to register the value
and exit edit mode. If another octet value must be changed, select it using the Select
button and repeat the editing procedure. Setting the I.P. Address to 000.000.000.000
will enable DHCP for this amplifier. Under this setting a connected DHCP server
will dynamically assign an I.P.Address to the amplifier.
Setting Amplifier ID
Use the Function button to choose Amp ID. Each Amp ID is composed of two,
two-digit hexadecimal values (see Appendix C for more information on Hex
Numbering).The upper two digits (the High Value) and the lower two digits (the
Low Value) can be independently adjusted. For this function, the Select button
toggles between these two values.
Select a value for adjustment, and press Edit. The selected portion of the ID will
flash, and the increment and decrement keys can now be used to adjust the value.
An amplifier’s I.P.Address can be used to designate an amp in a network, however
Amp ID is more useful for designation, particularly when DHCP is being used.
Network Examples
NexSys Modules 7
Amplifier IDs can remain fixed even if I.P.Address change, making the amplifier’s
settings and operating conditions easier to track. Additionally, creative use of the
High and Low Values in the Amp ID can provide even more information about an
amplifier. Since the two values can be adjusted independently, the High Value could
Firmware revision 0.2.61
and later allows two speed
value editing. For example,
when setting the IP Address
on the module, first select
the IP Address octet to be
edited. Then press the "Edit”
button. Next, press the up/
down arrow to increment/
decrement the value at a slow
speed. Or, press the up or down
arrow in conjunction with the
“Function” button to increment/
decrement the value at a faster
speed.
Not all function parameters
can be adjusted (e.g.AC Line
Voltage, Temperature, etc.) as
they are output values only.
Note: For instructions on
I.P.Addresses, designing
and setting up a complete
network, please see
