ASPI Bus

The ASPI Bus uses RJ45 connectors. These should

be used with category five twisted-pair cable.

The total distance of the ASPI Bus should be less

than 20 m.

RS-232 Port (9600 8-N-1)

The RS-232 port is wired as DCE. It accepts a male

DB-9 connector. Only pins 2, 3, and 5 are required

by the EF1210. Connect pins straight through (do

not use null modem).

Power Supply Input

The power supply input accepts a 5-pin DIN male

connector. Only use the power supply provided by

ASPI Digital. Use of other power supplies will void

the warranty.

Outputs, Rec, To CODEC, Zone Outputs

These audio connectors accept a mini (3.5 mm) 3

conductor terminal block (provided). See Note

below for manufacturer information.

From left to right the conductors are positive signal,

negative signal, and shield ground.

To avoid ground loops, do not connect shield ground

at both ends of the cable (except to microphones —

ground is required at both ends for phantom power).
