If the console is used in a multi-frame configuration then the busses need to be con-
nected in a ‘daisy chain’ fashion.
Each end
of a frame has seven bus connectors -
four audio and two data busses plus fader bus
. The bus cables are
simply linked between similar connectors on the end of the nearest frame.
Make sure that each frame has its “Frame Select” switch set to a different number.

When motor faders are used in extension frames, a 9-way “FADER COMMS” cable
must be connected between the CCM connectors shown
and the
COMMS input on the extension frame rear panel.
Extension frames fitted with motor-faders require control data from the CCM. Three
9-pin female connectors Three 9-pin female connectors located on the rear panel of
the CCM are connected directly to the extension frame using the supplied ‘fader
comms’ cable. The frame containing the CCM sends motor data fader data, via the
7303 interface module (always mounted directly below the CCM on J-type consoles).
Thus, a 3 frame console would require two “FADER COMMS” cables:
“FADER COMMS on EXTENSION FRAME 1 TO “FADER COMMS 2” on CCM
“FADER COMMS on EXTENSION FRAME 2 TO “FADER COMMS 3” on CCM

PFL mixing amplifiers are located in the “Oscillator/Communications” module. There
are two PFL outputs:

PFL Direct is a line level output that appears on an XLR 3-32 connector on the
rear panel of the OSC/Comms module, labelled “PFL DIRECT”;

PFL to Headphones is a high level output suitable for driving headphones that
appears on an XLR 3-32 connector and a TRS jack socket connector on the rear
panel of the OSC/Comms module, labelled “PFL TO HP”.
The PFL to Headphones signal can be connected to the TRS jack sockets mounted
on the front of the console frame by using the “OSC/COMM TO FRAME” cable sup-
plied. This cable has a male XLR 3-pin connector on one end and a female XLR 3-
pin on the other end. Connect one end of the “Oscillator/Communications” module’s
“PFL TO HP” connector and the other end to the rear frame connector labelled
