10.7 Firmware
The ADI-192 DD's main part has been realized using programmable logic. By exchanging a little
component called EPROM, 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 2.2. The firmware version is
displayed after power on by the SYNC and LEVEL LEDs of the INPUT MONITOR for about one
second.
Firmware 1.1: First firmware for the ADI-192 DD.
The current firmware 2.2 includes no bug fixes. Therefore owners of an ADI-192 DD with earlier
firmware will have to accept costs for an update to version 2.2. However these costs are limited
to material and work time (EPROM, flashing the EPROM, shipping).
Changes in firmware 1.2
1. The three sections OUTPUT now have a fourth setting, OFF. In this state no LED is lit. The
corresponding output provides an empty frame signal of the current sample rate. The option to
switch off specific outputs provides an even better overview to the user interface of the ADI-192
DD, as unused outputs no longer emit light signals.
2. The SOURCE LEDs of the three OUTPUT sections no longer light up constantly, but depend-
ing on the LOCK state. So when selecting an input without present input signal, the correspond-
ing LED in the OUTPUT section flashes in the same way as the ones in the SRC and CLOCK
SECTION. This change unifies the user interface of the ADI-192 DD and improves overview,
because invalid inputs will be recognized in any part of the user interface immediately.
3. The AES Sync display in the INPUT MONITOR section has been extended. In case multiple
AES signals with different ranges (Single, Double or Quad) are attached simultaneously and are
synchronous as well, flashing LEDs will indicate that these signals are still invalid for the cur-
rently chosen SRC mode.
4. New function
SRC Multi-range . Keep the button SRC RANGE pressed and both LEDs DS
and QS will light up. In INPUT MONITOR the LEDs DS and QS of the AES inputs will light up as
well. With this the SRC signals that now any input signal is accepted. Single, Double and Quad
Speed can be attached to the four AES inputs in any combination, and converted to any desired
output frequency. In this mode neither Double nor Quad Wire are supported as input signal.
Note: With firmware 1.2 the SRC LEDs of the OUTPUT sections have been changed from red
to blue. Unfortunately the orange QS LEDs were nearly identical to the red SRC LEDs. The
changed colour helps to notice an active SRC mode.
Changes in firmware 2.2
1. More sensitive mute for TDIF when encountering clock problems. Prevents noise in certain
situations with invalid clock. (v 2.1)
2. New function Follow Clock for automated CLOCK STATE switching.
