USL DAT-100 - Manual (Page 4)

- 4 -
The DAT-100 is a simple handheld AES/EBU digital audio generator designed to
assist cinema technicians debugging digital audio problems. The DAT-100 has two
25 pin output connectors to drive equipment with the USL or DMA8 digital audio
pinout. Substitution of the DAT-100 for an AES/EBU source allows the technician
to determine if a problem is in the source, the destination, or the cable between the
two. The DAT-100 can also be used for a quick check of downstream equipment
such as crossovers, power amplifi ers, speakers, and the speaker wiring. If audio
from the DAT-100 is heard in the auditorium, the equipment is working properly.
The DAT-100 allows the user to select which of the 16 audio channels are being
driven. It may also be used as a quick check that the appropriate speaker is being
driven by each audio channel.
The USL pin out is an industry standard pin out that was a proposed SMPTE stan-
dard that was never adopted. Note that the front panel of the DAT-100 shows this
as a “DCI Pinout.”
Introduction
Batteries
The DAT-100 is shipped with two alkaline AA batteries installed. As an option, it is
available with NiMH rechargeable batteries and an external charger.
When using rechargeable batteries and the USL supplied charger, turn the DAT-
100 power switch to the off position to charge the batteries. The batteries will not
be recharged when the DAT-100 is on. The DAT-100 cannot be powered by the
external charger.
Use only the USL supplied charger and only with recharge-
able batteries. Use of other chargers or batteries may damage
the charger, the batteries or the DAT-100.
