Legacy Board
As HX3.7 does no longer offer legacy analog and switch inputs, the HX3.7 LegacyBoard will be available to connect existing passive switch/button boards like Panel16 (2x8 = 16 inputs, two 10-pin headers), analog drawbar controls (2x12 = 24 inputs, two 16-pin headers) and a 6-way rotary vibrato switch (10-pin header). It provides the box headers of previous mainboards for up to 24 drawbars, 16 buttons/switches and vibrato rotary switch. The LegacyBoard is not needed for new installations using the MPX bus/connector (all DBX/PTX/ANX boards). LegacyBoard PL1/PL5 connect to HX3.7 PL31 PANEL I2C and PL32 ANLG MPX box headers as seen in picture. Route-through box headers (PL4/PL10, right) are provided for both, allowing easy daisy-chaining to MenuPanel or additional input boards.
Connection of analog and digital controls to HX3.7 LegacyBoard is made in the same way as for HX3.6 internal analog inputs and HX3.6 internal digital inputs:
- Connect old-style drawbars, old DB9/DB12/DB9 MPX drawbar boards or potentiometers to PL2 ANLG UPR and PL3 ANLG LWR of HX3.7 LegacyBoard
- Connect old Panel16 or buttons/switches to PL7 and PL8 of HX3.7 LegacyBoard
- Connect vibrato rotary switch to PL6 of HX3.7 LegacyBoard
- Insert jumper JP1 and JP2
Please note: On HX3.7 LegacyBoard, the internal analog inputs PL2 ANLG UPR and PL3 ANLG LWR are emulated by external analog MPX inputs (starting at param #5024 in HX3 Editor). Analog input assignments #5000 to #5023 do not exist on HX3.7, even with LegacyBoard connected. The parameters #5024 to #5047 are responsible instead.
Optional PL9 control output is available on OEM request (U13 and PL9 not populated on standard HX3.7 LegacyBoard). If U13 and PL9 are installed, remove jumper JP1 and JP2. This OEM Control Port provides the following signals on 7 outputs (high level = active):
| PL9 OEM Control Port | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Pin PL9 | Funktion | |||||||||
| 1 | Upper Secondary Drawbars active (LED+) | |||||||||
| 2 | Lower Secondary Drawbars active (LED+) | |||||||||
| 3 | Leslie/Rotary RUN (LED+) | |||||||||
| 4 | Leslie/Rotary FAST (LED+) | |||||||||

| 7 | unbenutzt | |||||||||
| 8 | Audio Enable (LED+) | |||||||||

LEDs can be connected directly if a series resistor (e.g., 470 ohms for red LEDs) is provided for each LED.
