Rotary Encoder & LCD Display: This control and display are used for initial setup of the AudiaEXPI unit. When power is first applied to
the unit, the display will cycle through a product description, followed by a title screen. Press the control to enter setup. Rotate the control
to make a selection, then press the control again to edit that selection. Additional levels of selection may be available using this same
routine. Some edits will require a choice of 'OK' or 'CANCEL. Some selections are only informational, and cannot be edited. Select
'BACK' to return to a previous level, and select '→' to advance. Primary selections are as follows
: COBRANET PARAMTRS (CobraNet
bundle, latency, & sample rate settings); AES3 PARAMTRS (various digital audio settings); WORD CLK OUTPUT (clock source); LOGIC
PRESETS (store/recall logic input presets); PASSWORD PROTECT (prevent tampering); TITLE DISPLAY (create custom title);

Digital Inputs: The four female XLR connectors provide a total of eight AES3 digital audio inputs in channel pairs (1-2, 3-4, 5-6, 7-8).
AES3 inputs are transformer coupled and should be wired using 110 ohm shielded-pair digital audio cable, with pin 2 (+), pin 3 (-), & pin 1
(ground). Input pairs 1-2 & 3-4 may each be selected for SPDIF input, and input pairs 5-6 & 7-8 may each be selected for TOSLINK input
(see Rotary Encoder above). SPDIF inputs are provided on RCA jacks and should be wired using 75 ohm coaxial cable, with Tip (+) and
Sleeve (ground). TOSLINK inputs utilize optical digital audio patch cables.
Word Clock Out: This BNC connector provides clock output from either CobraNet or a selected input source (see Rotary Encoder
above).
Logic Inputs: These eight Logic Inputs allow remote control of preset configurations. Preset configurations may be assigned to Logic
Inputs 1~8 using the front panel Rotary Encoder (see above), and can then be selected via external contact-closures (wired from the
corresponding logic inputs to ground).
CobraNet: These two RJ45 connectors provide the CobraNet digital audio interface. CobraNet allows multiple AUDIA units to share
digital audio (and DSP resources) on a system network. This also allows AUDIA units to be used with CobraNet compliant devices from
other manufacturers. A 10/100Base-T Ethernet switch (not hub) is required when networking multiple units. The maximum distance
between any unit and an Ethernet switch is 100 meters. Additional Ethernet switches, or even fiber-optics, can be used to further extend
distances between units on a system network. The primary and secondary CobraNet ports are redundant. CobraNet supports 64
channels of digital audio (32-in & 32-out) over Fast Ethernet, using CAT-5 cable. CobraNet transmits (32) channels of digital audio on (4)
'bundles' of (8) channels each. The same is true for receiving digital audio over CobraNet. Bundle numbers are used to determine where
digital audio is transmitted and received. Typically, 'unicast' bundle numbers (256~61,439) are used to exchange digital audio between two
specific devices. With 'unicast' bundles, each CobraNet device can transmit to no more than (4) other devices within a network. With
'multicast' bundle numbers (1~255), digital audio can be exchanged with multiple devices. Due to network delay, CobraNet has a limitation
of seven (7) 'hops' (one-way transmissions) within a network.
In order to integrate AudiaEXPI-D into a AUDIA system, an EXPI-D (or CobraNet) input block must first be placed into the design layout.
AUDIA units intended to receive digital audio from the AudiaEXPI-D must have their CobraNet jacks connected to the same network. Both
the AudiaEXPI-D unit (hardware) and the EXPI-D input block (software) must be assigned matching bundle numbers, before digital audio
can be successfully exchanged. AudiaEXPI-D bundle number assignment can be changed in real-time to allow routing of digital audio to
different EXPI-D input blocks within the system. CobraNet Latency settings must be identical in all devices, system-wide. Also, unicast
and multicast bundle numbers can be used to route digital audio to individual or multiple EXPI-D input blocks. Similar considerations may
also apply when using AudiaEXPI-D with other CobraNet compliant systems or devices. AudiaEXPI-D and AudiaEXPO-D can exchange
digital audio directly (outside of a system network) using either a simple 'cross-over' CAT5 cable or an Ethernet switch.
