NOTE:
Dotted lines represent signal flows inside the AXI 016. Solid lines represent signal flows over CAT 6 cable.

Basic Signal Flow from Primary EXP Device to AXI 016
Connecting a Primary EXP Device and Secondary EXP Device
The diagram below displays the signal flow when a primary EXP-enabled device is connected to the
EXP INPUT
port and a
secondary EXP-enabled device is connected to the
EXP THRU
port.
•
All 16 Expansion output channels of the secondary device are routed through the AXI 016 and into the primary EXP device
Expansion input channels (see path B in the figure below).
•
All 16 Expansion output channels of the primary EXP device are routed to the 16 analog line outputs of the AXI 016 (see path
A1 in the figure below). Expansion output channel 1 of the primary EXP device is routed to the AXI 016 line output 1, and so
on.
•
All 16 Expansion output channels of the primary EXP device are also routed to the Expansion input channels of the
secondary EXP device (see path A2 in the figure below). Expansion output channel 1 of the secondary EXP device is routed
to Expansion input channel 1 of the primary EXP device, and so on.
