CADI REMOTE CONTROL
The CADI (Controller/Autolocator Desktop Interface) remote control is a centralized
control surface designed exclusively for controlling up to eight Alesis M20 digital
multitrack tape recorders. The CADI essentially duplicates the front panel of the master
M20 (identified as ID1), and adds controls specific to multi-machine applications.
Most of the CADI controls operate bi-directionally. Example: if you press a record button on
an M20 controlled by the CADI, the corresponding CADI record button will light, and vice-
versa. However, Alesis recommends performing all commands directly from the CADI
unless a machine is offline. Offline machines operate independently of the CADI.
In general, CADI buttons initiate the same operations as like-named buttons on the master
M20. For example, pressing Stop on the CADI is equivalent to pressing Stop on the master
M20. Therefore, this document covers only those aspects unique to the CADI and should
be inserted into the binder with the M20 manual.

INSTALLATION
The CADI is intended for use on a desktop, or attached to the optional Alesis BRC
Rollaround Stand, available from your dealer. Attach the CADI’s bottom panel to the
baseplate of the BRC Stand via the four included screws, NOT to the side panels. The
CADI is not rack-mountable.
CONNECTIONS
The master M20 connects to the CADI via a standard Category 5 cable, terminated at both
ends with RJ-45 connectors (these cables are common in Ethernet systems). All other slave
ADATs connect to the system via the optical and 9-pin cables, as described in the M20
manual.
Do not connect the RJ-45 connectors of the CADI, RMD, or M20 to any other type
of equipment or to an Ethernet network. Connect only to Alesis
products.
If you are also using the Remote Meter Display (RMD), the master M20 patches into the
RMD via an RJ-45 cable. The RMD then patches into the CADI with a second RJ-45 cable.
With multiple M20s and RMDs, each M20 feeds an RMD. The RMD that connects to the
master M20 then patches to the CADI.
AC POWER
The CADI works with any AC voltage from 90 to 250 volts, 50 to 60 Hz. This eliminates the
need for transformers or voltage switches. The CADI ships with an IEC-spec power cord
for the country to which the CADI was shipped.
The CADI’s IEC-spec AC cord is designed for connection to an outlet that
includes three pins, with the third pin connected to ground. Do not
substitute a non-grounded AC cord or lift the ground.
The ground connection is an important safety feature designed to keep the chasis of
electronic devices such as the M20, CADI remote, or RMD at ground potential.
Unfortunately, the presence of a third ground pin does not always indicate that an outlet is
properly grounded. Use an AC line tester to determine this. If the outlet is not grounded,
consult with a licensed electrician. When the AC current is suspected of having unstable
voltage and/or frequency, a professional power conditioner should be used.
The CADI is supplied with a standard detachable power cord. If the AC cable is too long
or short for the installation, you may substitute a UL-approved power cable of the proper
length, available in many electronics or computer stores (type “NEMA to CEE”).
When powering up, turn on the master (“ID1”) M20 first, then any slave M20s, then any
RMDs, and finally, the CADI.

On power-up:
•The display will briefly show the software version of the CADI’s internal ROM.
Note: this is NOT the software version of the connected M20.
•The Bank 1-32 button lights.
•The Online buttons for any connected M20s or ADATs light (offline M20s are placed
online when the ID1 machine detects the CADI).
•The Aux Group Select button lights.
•The Search mode light always indicates the CADI wheel position, not that of any online
machines. Example: If the CADI wheel is set to Shuttle and the master M20 wheel is set
to Jog, “SHTL” will light on the CADI and “JOG” will flash on the master.
•The CADI displays the status of the ID1 (master) machine, as well as the Record/Input
Enable status and online status for every machine shown on the CADI front panel.
If you turn off the ID1 M20, the display will revert to the “A l e s i s C A D I” start-up
message.

CADI MANUAL 1.00 C-7
BANK SELECTION AND TRACK ENABLES
The CADI has record and input buttons for four M20s, arranged as four groups of 8. There
are also four sets of record and input select buttons for the Aux/TC tracks. Two buttons,
Aux and TC, enable the Aux or TC tracks for input and record enabling. (Note: If tracks are
enabled on a “background” track enable bank or an Aux/TC group, the appropriate bank
select button flashes.) All these buttons light when active.
Two Bank select buttons determine whether the record and input buttons control M20s 1-4
or 5-8. With Bank 1-32 selected, the four groups of buttons control inputs 1-8, 9-16, 17-24,
and 25-32. The four sets of Aux/TC buttons control M20 1 through M20 4.
With Bank 33-64 selected, the four groups of buttons control inputs 33-40, 41-48, 49-56, and
57-64. The four sets of Aux/TC buttons control M20 5 through M20 8.
Note: If a machine with record- or input-enabled tracks goes offline, the CADI still indicates
the track enable status, but this status cannot be changed until the unit goes online again.
CONTROL OF OTHER ADAT MODELS
In a system with a master M20 whose Sync Out jack is connected to an ADAT, ADAT-XT,
ADAT-XT20, LX20 or similar machine, control of basic functions such as transport
movements, arming tracks etc. is possible for all ADATs in a system. However, control is
limited. For example, the ONLINE button will light for an ADAT-XT20, but pressing the
button cannot take the XT20 offline. Other ADAT models will chase to the M20 when it is
in jog or shuttle mode, but since their transports are different it is normal for them to stop
and start or relocate when jog or shuttle is used.
Please keep in mind that mixed systems can not give the fast lock and wind times of an
all-M20 system, and that other anomalies are possible, especially with older
machines or machines that do not have updated software.
CADI, Appendix C
C-8CADI MANUAL 1.00
MACHINE SELECTION AND STATUS
ONLINE/SELECT BUTTONS (1-8)
Each Online button toggles the online status of the corresponding connected M20. A lit
button indicates an online M20. If an online machine becomes disconnected (e.g.,
communications error, sync cable disconnection, power off, etc.) while this button is on, the
corresponding machine’s button turns off and the display shows “Last Slave
Unresponsive” before re-establishing the status of the remaining series of slave machines.
Notes
•If an M20 is recording, it cannot be toggled offline.
•If an M20 is in Play, Rewind, FFwd, or Locate mode, putting it offline stops the tape.
•Pressing an Online button for an unconnected M20 yields a “No Machine Present”
prompt until communication is re-established.
•If the CADI is in a mode or parameter page that uses the Online buttons as Edit Select
buttons, a machine cannot be set on or offline. After exiting edit mode, the
Online/Select buttons default to indicating the system’s online status (no buttons
flashing).
•To find out how many M20s are connected, Utility page 16 (ID status) displays “nn
ADAT(s) connected” (nn = 01-16).
MACHINE EDIT SELECT
The Online buttons can also select a single machine for editing of the following parameters:
•Format
•Tape Offset
•Track Delay
To select a machine for editing:
1. Enter the Mode or Edit page for the parameter to be edited.
2. Press the Online/Select button for the machine whose parameter(s) will be edited.
Only one machine can be selected for editing at a time; its corresponding Online/Select
button will flash. The Online buttons for any other online machines will be lit solid. If a
slave is offline, it cannot be selected for editing.
The machine edit select reverts to ID1 if the master machine is turned off and on again.
Example: If the ID3 machine was selected for editing and the ID1 machine is turned off,
when ID1 is powered back up and you return to one of the appropriate edit pages, ID1 will
be selected for editing, not the ID3 machine.
