2.3 Rear Panel
The rear panel of the AERO.lite contains its electrical, signal, and control connections.
Specific pinout information for GPI I/O is provided in Chapter 5.

2.3.1 GPI/O
Connect dry contact closures here to for external control of certain functions. For
example, you may wish to set up a means to recall a “Bypass Processing” preset if EAS
is inserted ahead of the AERO.lite (though installing your EAS unit after the AERO.lite is
preferred). Note that GPI functions require held closures for the duration of the desired
function.
2.3.2 ETHERNET
10/100 BASE-T Network connection used for firmware upgrades and SNMP reporting.
2.3.3 SDI I/O
Permits de-embedding and re-embedding any of the 16 available channels in an applied
HD-SDI or SD-SDI signal.
NOTE: Appropriate reference must be applied AND selected for proper
operation. To aid in this critical setting,
if SDI embedding is enabled, the
clock source will automatically be set to SDI.
2.3.4 AES I/O
Inputs and outputs for 75-Ohm digital audio input and output. Note that the sync
reference can be set to use this AES Input, or if the input signal is not referenced to the
plant or is at a rate other than 48kHz, select the AES or SDI reference.
2.3.5 AES Reference I/O
Use AES Reference I/O to resynchronize the AERO.lite to an external reference, and be
sure to choose AES Ref as the clock source in the Setup->I/O menu. Note that the AES
Reference output is active and is locked to the selected reference signal (Internal, SDI,
AES In, AES Ref In).
2.3.6 Analog I/O
Connect left- and right-channel analog Inputs and Outputs here. If you intend to use the
internally-generated 48kHz reference signal, the analog inputs and outputs can be
employed with no need for external reference signals.
