CMG-EAM (Platinum Firmware)
this application. In the illustration above, a digital instrument's GCF
output is retransmitted as SEEDLink data over Ethernet.
1.4.3 Array Concentrator
The CMG-EAM is well suited to combining the data from a number of
instruments in an array and retransmitting them over a single link
(serial or network).
If the output link is over a network, all three serial ports of a standard
CMG-EAM (including the “DATA OUT” port) are available for
connection to digitisers or digital instruments, allowing up to eighteen
channels to be aggregated. An arbitrary number of CMG-EAMs may be
chained together, allowing for even more extensive arrangements.
