Het is geen seriele (RS232/485/422) verbinding, er is gebruik gemaakt van een connector die normaliter voor seriele verbindingen wordt gebruikt. Google leverde het onderstaande resultaat. Met behulp van deze pinout zou het mogelijk zijn om een kabel te maken van DB9 naar de midi DIN pluggen.
May try the following, found here:
Multimedia Production Forums - View topic - E-MU 1616 Midi Breakout Cable Wiring
EMU 1616M Midi Octopus Pinouts
DB-9 Male, DIN5 Female
1 -- NC
2 -- 1-OUT, PIN-4
3 -- 1-OUT, PIN-5
4 -- 2-OUT, PIN-4
5 -- 2-OUT, PIN-5
6 -- 1-IN, PIN-4
7 -- 1-IN, PIN-5
8 -- 2-IN, PIN-4
9 -- 2-IN, PIN-5
PIN 2 OF 1OUT AND 2OUT CONNECTED TO METAL SHIELD OF DB9 SHELL ( ! )
PIN2 OF 1-IN AND 2-IN NC (NO CONNECTION)
Note that they put the 9-pin cable on there to facilitate a 2-in-2-out MIDI capability. (Otherwise, they would have to had put four large round MIDI sockets on it).
Just prepare your four cables, and do one at a time...DB9 Pin2 to first one (1 out) Pin 4, DB9 Pin3 to the same one (1 out) Pin5, and then connect Pin2 of the same DIN5 to the metal shield of the connector. And then, LABEL each one as you finish!
Then, work your way through the rest of them.
By the way, note the unusual numbering of the pins on the MIDI connector:

They don't start at one end, and count through to the other 1,2,3,4,5. Note that they only use the middle three pins, and those are 5,2 and 4. Don't confuse those, or it definitely will not work!
I can't verify the correctness of this! Use this at your own risk! This is the only thing I found through a quick search.
If you are ONLY concerned with using one single MIDI in/out, you COULD probably just connect the stuff for MIDI 1, and skip the MIDI 2 stuff. In fact, it may be a good idea to just do one, and see if it will connect successfully to another unit, before continuing, if you did want two.
Make sure you put plenty of strain-relief on that connector, somehow. Obviously, four MIDI cables won't fit inside the hole left for the DB9 cover, so you'll have to figure out a way to cut the jackets up to a certain point, so all the wires will pass through the opening, and provide enough support for the two or four dangling cables to get tugged on without continually breaking off wires at the DB9 connector. I don't know if a small zip-tie to clinch down the wire bundle will fit inside the DB9 shell, to prevent pulling? And then, maybe a few layers of progressively larger heat shrink to take care of the "bending/broken wire" situation that will occur right at the shell opening, without it? The heat shrink could go an inch or so out to meet the jackets of the MIDI cables, and then you'll have to bundle those two or four together for a couple inches, overlapping the heat shrink from the wire bundle.
Let us know if it works?
