Inputs and Outputs
Types of Input and Output
Backplanes with Coax Connectors
These backplane modules have coax (Din 1.0/2.3) connectors:
The coax backplanes are used for standard I/O, disembedder cards, embedder cards, MADI cards
(a.k.a, TDM cards), and AES async cards.
Generally, the coax input backplanes have 9 ports. The output backplanes have 18 ports. The
expansion output card has 9 ports and two 28-pin expansion connectors.
The frame sync input backplane has an additional Ethernet port for the configuration of the
frame sync card.
When these backplanes are used with hybrid I/O cards, one or two of the ports remain unused.
The M3 output backplane module is unique. It has a single 16-port “M3” connector supporting
16 of the outputs of the M3 card. The two remaining ports are presented on two coax connec-
tors. See
Backplanes with WECO Connectors
These backplane modules have 3- and 5-pin WECO quick-release connectors:
Backplanes with WECO connectors are used for balanced AES async inputs and outputs. These
backplanes are for asynchronous AES cards only.
The input backplanes have 9 ports. The output backplanes have 18 ports. The expansion output
card has 9 ports and two 28-pin expansion connectors.
