12 x UAP-711i/712i
2.5.4 Fixed or remote controlled delay
The module can delay the signal up to 10 sec (@48 kHz). This delay can be user adjusted (Fixed
mode) by 1 ms step. A part of the maximum delay can be reserved and applied by a remote controlled
signal (Tracking mode).
This signal uses electrical transport of a RS 422 path.

Figure 9: Tracking signal
The signal period corresponds to the maximum delay reserved by the main module (T) and the positive
pulse width (tproc) corresponds to the required delay. For a sudden variation, UAP-711i or UAP-712i
integrates this modification within 15 sec for a variation of 40 ms.

The reserved part of delay is subtracted from the accessible entire delay value in “fixed” mode if the
“tracking” mode is active. Up to four modules can share the same tracking signal.
2.5.5 0dBFS
The three switches SW1, SW2 and SW3 set the RMS value of sine wave corresponding to a 0 dBFS
digital level with gain adjustments set to 0 dB.
2.5.6 GPI Outputs
Four open-collector GPI outputs (two for each channel) are available on the GPI socket. For each
channel, one output is dedicated to a signal overload (with analog or digital input selected) and the
other to a no-lock condition on the digital input. In the absence of alarm, no current flows through an
output pin. These outputs are inactive when the alarms are disabled (ALRM menu, OFF selected)
