16.1.2 MIDI Interfacing
A MIDI breakout cable is supplied with the automation package. This cable has a male DB-
25 on one end, and ten (10) male 5-pin DIN connectors on the other. The DB-25 connector
interfaces with MIDI I/O (DAW CONTROL) connector on the rear of the console. The ten DIN
connectors interface with the MIDI In and Out ports on the DAW. The DIN connectors are
labeled as follows:
MIDI 1 IN
MIDI 1 OUT
MIDI 2 IN
MIDI 2 OUT
MIDI 3 IN
MIDI 3 OUT
MIDI 4 IN
MIDI 4 OUT
MIDI 5 IN (MTC)
MIDI 5 OUT (not used)
MIDI IN and OUT 1-4 support DAW control for up to 32 channels. Each set of ports is
mapped to an 8-channel fader module via 1608 software (see section 14.0 DAW Control).
Therefore, the MIDI IN and OUT 1-4 connectors need to be interfaced with the MIDI ports
on the DAW that are configured for HUI control.
MIDI 5 IN supports MIDI timecode (MTC). It should be interfaced with the MIDI Out port on
the DAW that is configured to provide MTC when its transport is started.
MIDI 5 OUT is currently not used.
The standard MIDI breakout cable supplied with the automation package is thirty (30) feet
in length. Other lengths can be ordered and cables of up to fifty (50) feet in length have
been tested successfully. Performance can vary with the environment in which the system is
used.
16.1.3 Expander Interfacing
If the 1608 console and automation package are expanded to 32 or 48 channels, each 1608
EX expander must be interfaced with the ACM in the main console.
Automation expander cable(s) will be supplied with the automation package. Each cable is
terminated with male DB-25 (D-sub) connectors on each end. The cables are connected as
indicated in the diagram below.
Expander Chan. 17-32
Main Console
Expander Chan. 33-48
NOTE: Typically the data port on all 1608 EX expanders is mounted in the 17-32 position
(although it can easily be moved at customer request.)
MIDI interfacing is provided via a female DB-25 (D-sub) connector
on the rear panel of the console. This MIDI interface supports DAW
control and synchronization using MIDI timecode (MTC).
