6. If an external controller (eg. Vega tone-remote adapter) is to be connected to the system, all wiring
should be made to the DB25 connector or to the optional screw-type A-PNL-AUX96-3 auxiliary terminal
connector shown in Figure 2-3.
The female DB25 connector can be used for basic base connections to a Vega DSP-223 or IP-223,
using a standard straight-through male-to-male DB25 cable.
WARNING: JU108 must be configured correctly for DSP-223 or IP-223 or damage can occur.

The plug in screw connectors on the A-PNL-AUX96-3 can be removed to allow for easy connection of
the wires.
For some applications, a cable, not a terminal strip connector, is used to connect to the auxiliary
connector. The cable must be plugged into the P1 auxiliary connector shown in Figure 2-2 on the rear
of the subrack. Ensure locking tabs on the connector are completely engaged.
