Hardware Setup Guide
1 1. Available I/O Options DME32 has four "MY-Card"(Mini-Yamaha Generic Digital Audio Interface) Slots for I/O. Each card slot can handle up to 8 channels of I/O for a maximum of 32 I/O per DME32 unit, depending on the cards chosen. SLOT 4 SLOT 3 SLOT 2 SLOT 1 The current MY-Cards available from Yamaha are a variety of analog and digital formats. It is possible to mix analog and digital cards in a single DME32 unit.
These are the current Remotable External Input/Output devices from Yamaha: 2 Front Panel Rear Panel AD824 Eight 24-bit Mic/Line Level Inputs on XLR, with Balanced Inserts on 1/4” TRS connectors, and +48V Phantom Power. All Functions (Gain Trim and Phantom Power On/Off) can be controlled remotely via RS-422 (up to 200 meters away). This device accepts one digital MY-Card for its outputs.

3. Digital I/O 4 Each of the digital MY-Cards are capable of 8 channels of input and output (MY8-AE, MY8-AT, MY8TD). Different format cards can be used together in a single DME32 unit. You can also mix analog and digital cards together in a single DME32 unit. For 8 Channels of Digital I/O: Use one digital MY8 card.
5 4. Using the AD824 and DA824 The AD824 and the DA824 have MY-Card slots as well. Using digital MY-Cards, an audio connection between the DME32 and the AD824 and/or DA824 can be established. Using AES/EBU (MY8-AE Cards), distances of 200 meters can be achieved. Using ADAT optical transmission (MY8-AT cards), you can separate the units by 6 meters.

Up to 200 meters of separation between the DME32 and the I/O components is possible. In the example above, a split AES/EBU cable is utilized to connect the DME32 to the AD824 and DA824. See the next section for details on creating this cable.
7 5. Creating Split AES Cables The MY8-AE Card is capable of 8 AES/EBU inputs and outputs via a 25-pin Female D-sub connector. In order to use this card with a DME32 and AD824/DA824 configuration, a split AES/EBU cable must be created. You must use shielded 110-ohm twisted-pair AES cable and 25-pin Male D-sub connector on each end.
8 The pin configuration is as follows: D-sub 1(DME32) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 D-sub 2 (Input) 5 6 7 8 D-sub 3 (Output) 1 2 3 4 10* 12* 13* 18 19 20 21 14 15 16 17 22* 23* 24* 25* Signal Description Input 1/2 + Input 3/4 + Input 5/6 + Input 7/8 + Output 1/2 + Output 3/4 + Output 5/6 + Output 7/8 + No Connection GND No Connection GND GND Input 1/2 Input 1/2 Input 1/2 Input 1/2 Output 1/2 Output 1/2 Output 1/2 Output 1/2 GND GND GND GND *Optional Connection Al
6. AD824 Connection for Remote Control The AD824 can be controlled remotely from the DME32 via RS-422. Gain Control and Phantom Power On/Off can be manipulated and recalled by the DME32. In order to do this, RS-422 Cables need to be run from the DME32 to the first AD824, and then daisy-chained to subsequent AD824 units.
10 AD824 ID numbers are automatically set by their position in the chain. The first AD824 connected to DME32 is unit #1, and the second AD824 is unit #2, and so on. The IDs have no relation to the slot number they are plugged into. The ID numbers should be noted and will be used by the software to address them.
