13.6 Firmware

The ADI-642's main part has been realized using programmable logic. By re-programming of a
little component called Flash-PROM, both function and behaviour of the unit can be changed at
any time.
At the time of writing this manual, the unit is shipped with firmware 2.1. The firmware version is
displayed after power on for about one second by the SYNC and AUDIO LEDs of the AES
INPUT STATE section.
V 1.1: Initial release
V 1.2: ADC slave mode allows to configure the Matrix via the unit's controls
V 1.4: Baud rate 38400 added. MIDI initialization reworked
V 2.1: Follow Clock and Lock Keys added

13.7 Connector Pinouts

AES/EBU
The XLR connectors are wired according to AES3-1992:
1 = GND (shield)
2 = Signal
3 = Signal
AES/EBU and SPDIF are biphase modulated signals, therefore polarity doesn't matter. Pins 2
and 3 are neither hot nor cold, they carry the same signal. But as AES3 uses a balanced trans-
mission they are inverted in polarity.
RS-232
The 9-pin D-sub Connector is wired according to industry standard:
Signal In (Rx) Out (Tx)
D-sub 2
Internally connected are pins 1 with 6 and 4, and pin 7 with 8.
