HomerLink
HomerLink is a data bus format designed by Symetrix which allows 4 mono bi-directional AES-3 digital audio channels to be
transmitted between devices up to 100 meters apart over standard CAT-5 cable. The DigIO features two HomerLink ports
which provide audio I/O channels 5-8 and 9-12. These two ports can be connected to one of two types of HomerLink BreakOut
modules, the AES4 and TOS4. The AES4 provides AES-3 inputs and outputs on 2 pairs of XLR connectors. The TOS4 provides
S/PDIF optical inputs and outputs on 2 pairs of TOSLINK connectors. Each HomerLink BreakOut module is a half rack device,
and any combination can be fitted side-by-side in a one rack space chassis to provide all remaining DigIO audio I/O channels
(5-12) in a single rack space breakout.
Warning!
The HomerLink RJ-45 connectors should ONLY be connected to other like HomerLink RJ-45 connectors.
NEVER connect HomerLink connectors to any other RJ-45 connectors.
800HLA4 - 4 channel AES-3 BreakOut
800HLA8 - 8 channel AES-3 BreakOut
800HLAT - 4 channel AES-3 and 4 channel S/PDIF Optical BreakOut
800HLT8 - 8 channel S/PDIF Optical BreakOut
800HLT4 - 4 channel S/PDIF Optical BreakOut
Interconnecting DigIO’s with HomerLink
The DigIO’s HomerLink connections can be used in scenarios where it is advantageous to share digital audio between two
independent rings without CobraNet. Simply add a DigIO to each ring, and connect up to 8 audio channels in each direction via
the two HomerLink connectors. A custom HomerLink Double-Crossover cable must be used. This cable swaps both RX pairs
with both TX pairs (as opposed to normal Ethernet crossover cables, which only swap one RX/TX pair). Symetrix has available
a six inch HomerLink Double Crossover Cable kit, part number 810HLXO which features a male RJ-45 on one end and a female
RJ-45 on the other configured with the necessary double-crossover wiring. This adapter kit allows the use of standard CAT-5
cable of needed length to be used when connecting two DigIO’s together via their HomerLink ports. (One crossover adapter
needed per HomerLink port).
