Master/Slave Operation

Transmit mode ‘tr. -’.

Transmit Off

Selecting this mode allows MIDI transmit to be switched off, whilst still
allowing MIDI receive to be functional. It is of use mainly in large MIDI
control setups and controls data to the MIDI OUT socket only.

This is a full Master/Slave linking mode where all delay settings, in/out status,
and temperature data is transmitted by the Master unit for duplication on each
slave unit. Program recall and level information is not transmitted and remains
locally adjustable.

For this mode you can only mix 

TCS-803

 and 

TCS-804

 units within a system if

the latter is set to its mono mode, and similarly all 

TCS-804

 units within the

same system must be set to the same mono/dual channel mode. The error
message ‘Err.5’ will be displayed if this is not the case.

Transmit mode ‘tr.SL’.

Transmit Slave

A change in this mode measns only program recall and temperature data are
transferred. When you Recall a program on the master, all other
interconnected units will respond by recalling their own program with the
same number. If the display is set to Program number on the slave units,
confirmation of program change will be shown.

Temperature data is also transferred so that the stored distance information
from the slave units' programs will allow temperature compensated delay
times to be shown.

Transmit mode ‘tr.Pr’.

Transmit Program

This mode is for transferring temperature data only, between Master and
Slave. It suppresses all data except temperature on the MIDI interface and
therefore allows a BSS temperature probe connected into the master to act for
all other interconnected units. Where temperature compensation is desirable,
this will avoid having to install a BSS probe for each unit in the system.

Transmit mode ‘tr t

°

’.

Temperature Linking

By using the MIDI control interface it is possible to interconnect a number of

TCS-803

 and 

TCS-804

 units so that one unit takes on a MASTER function while

other selected ones assume a SLAVE function. In addition there are three
different modes of operation to choose from determining what data is to be
transferred. Select this from within the UTILITY menu at the same time as
setting MIDI channel number. 

Refer to section 10

.

Using standard MIDI DIN connecting leads, link the MIDI OUT socket of the
unit you wish to be MASTER to the MIDI IN socket of the first SLAVE unit.
Continue in a ‘daisy chain’ fashion linking MIDI THRU to MIDI IN on all the
other units that are to be controlled. (The MIDI out socket is only used on the
MASTER unit).

Be sure to set equal MIDI CHANNEL numbers for all units, and set the
required transmit mode on the MASTER.

When a master unit is first powered up, after a few seconds it will transmit all
selected parameters to the slaves. If there is any doubt as to whether the slave
units are ready to receive the initial data, check that the slaves are NOT
powered up after the master, or that cabling is done after the master is turned
on. A second initial dump of data can be sent by altering the transmit mode
on the master and then returning it back to that required. Thereafter
parameters are only transmitted from the master when they are altered.
