ALESIS PDAT SYSTEM EXCLUSIVE
The PDAT responds to all Alesis system exclusive ADAT commands, as well as MIDI Machine Control (MMC)
commands. In addition, the PDAT also responds to and sends out Alesis system exclusive PDAT commands to access
functions that may or may not be addressed by PDAT or MMC commands.
Note: There may be some overlap in commands. For example, setting a locate address may be done using MMC,
ADAT Sysex or PDAT Sysex commands.
The PDAT has the following MIDI System Exclusive format:
F0H Start-of-Exclusive
00H 00H 0EH Alesis manufacturer ID
16H PDAT product ID
aaH Device id# (0..7EH, 7FH=all)
bbH Opcode (0..7FH)
data Data
F7H End-of-Exclusive

11H - MIDI Software Dump
F0H 00H 00H 0EH 16H <dev#> 11H <type> [data] F7H
<dev#> always = 7FH
<type> can be:
04 Meg Flash Boot segment data without interleaved checksum
14 Meg Flash Code segment data without interleaved checksum
24 Meg Flash Boot segment data with interleaved checksum
34 Meg Flash Code segment data with interleaved checksum
48 Meg Flash Boot segment data without interleaved checksum
58 Meg Flash Code segment data without interleaved checksum
68 Meg Flash Boot segment data with interleaved checksum
78 Meg Flash Code segment data with interleaved checksum
If <type> is 0,1,4, or 5 (data without interleaved checksum) then [data] is:
<#data bytes> <24 Bit Address> <data byte 1> .. <data byte N>
.. .. .. ..
<#data bytes = 2> <24 Bit Address = 0> <checksum word>
where: <#data bytes> is sent as a single byte greater than 0 but less than 128.
<24 Bit Address> is sent as 6 nibble-ized data bytes. For example, address 123456H is sent as
01H 02H 03H 04H 05H 06H. MSB first.
<data byte> is sent as 2 nibble-ized data bytes. For example, data 98H is sent as 09H 08H.
MSB first. <data byte> is repeated for <#data bytes>.
<checksum word> is sent as 4 nibble-ized total checksum bytes. Note <#data bytes> must equal
2. <24 Bit Address> must equal 0.
Repeat the <#data bytes> <24 Bit Address> <data byte 1> .. <data byte N> sequence for programming of
additional flash locations. Note that the <24 Bit Address> specifies the start of programming location for
the specified <data byte>’s. Always complete the end of the transmission with the checksum sequence
above.
If <type> is 2,3,6, or 7 (data with interleaved checksum) then [data] is:
<#data bytes> <24 Bit Address> <data byte 1> .. <data byte N> <checksum>
.. .. .. .. ..

<#data bytes> <24 Bit Address> <data byte 1> .. <data byte N> <checksum>
where: <#data bytes> is sent as a single byte greater than 0 but less than 128.
<24 Bit Address> is sent as 6 nibble-ized data bytes. For example, address 123456H is sent as
01H 02H 03H 04H 05H 06H. MSB first.
<data byte> is sent as 2 nibble-ized data bytes. For example, data 98H is sent as 09H 08H.
MSB first. <data byte> is repeated for <#data bytes>.
<checksum> is sent as 2 nibble-ized checksum bytes.
The checksum is the sum of the previous <data byte> sequence mod 256.
Repeat the <#data bytes> <24 Bit Address> <data byte 1> .. <data byte N> <checksum> sequence for
programming of additional flash locations. Note that the <24 Bit Address> specifies the start of
programming location for the specified <data byte>’s.
