Midi Implementation Summary - Mackie SR40.8 Owner's Manual

Using the DATA Port
The DATA port on the SR40•8/56•8 mirrors
the MIDI ports, transferring MIDI information
between an external computer's RS-232 serial
port and ULTRA MUTE. The only difference be-
tween using the DATA and MIDI ports is the
rate of transmission of the data and the gen-
eral physical hardware (9-pin Sub D vs. 5-pin
DIN, respectively). The actual data transferred
is the same.
The DATA port provides two-way communi-
cation of data between devices. Pin 2 is RXD
(receiving line), pin 3 is TXD (transmitting
line) and pin 5 is ground (shield).
If your computer has an RS-232 port, the
connecting cable should be wired as follows:

1 The RS-232 serial port is configured to oper-
ate at 19.2k baud at the factory. An internal
jumper provides the option of changing the
baud rate to 9600 baud or 38.4k baud. Please
refer to the SR40•8/SR56•8 Service Manual,
or contact Mackie Technical Support at 1-800-
258-6883 (8am to 5pm PST), for details.
Note: The MIDI port operates at 31.25k baud,
as defined by the MIDI Manufacturers
Association's (MMA) MIDI Specification.

Notes regarding version 1.2 of the firmware:
1. MIDI Sysex Message number "00 00"
(requests all snapshots, all at once) may
encounter errors due to buffer problems in
some sequencing software. If you are
unable to successfully execute this request,
use "00 01" (requests all snapshots, one at
a time).
2. MIDI Sysex Message numbers "02 00" (re-
quests all groups, all at once) and "02 01"
(requests all groups, one at a time) do not
work in this version. Sets 1-8 are trans-
ferred, but not Set 9. A suggested
workaround is to create a string using mes-
sage request number "03" to request groups
from each of the nine sets. For example:
19.2k 1
None
