Introduction 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.
AES/EBU Outputs The DAT-100 has two 25 pin D connectors providing AES/EBU digital audio outputs. The top connector provides eight AES/EBU pairs (16 audio channels) using the USL pinout. The bottom connector provides 8 AES/EBU pairs (16 audio channels) using the Dolby DMA8 pinout.
Switches, Indicators & Connectors On/Off Switch Slide the switch to the on position to turn on the unit. Slide the switch to the off position to turn the unit off and enable the optional external battery charger. Power Indicator The power indicator lights when the unit is on. It flashes when the batteries are low and need replacement or recharging. Source Button and Indicators The source indicators show which audio source (tone, pink noise, or channel ID) is currently driving the output.
DAT-100 Operation Plug an AES/EBU cable in to the appropriate output jack. Slide the power switch to ON. The BATTERY, TONE, MANUAL and “L” LEDs light. The BATTERY LED indicates the unit is on. If the BATTERY LED is flashing, the batteries need to be replaced or recharged. The TONE LED indicates the DAT-100 is producing a 1kHz tone at -20dBFS. The MANUAL LED indicates the unit is in Manual Mode. “L” LED indicates that the Left output is being driven in 8 channel mode.
Source Pressing the source button advances the source selection to the next source. The DAT-100 can output a 1kHz tone at -20dBFS, pink noise, and a spoken channel identifier. The source LEDs indicate which type of sound is currently being output. The spoken channel identifier speaks the channel name (ie, L, LC, C, RC, etc.) or number (9, 10, 11, etc.) in English. The SW channel produces a 100Hz tone at -20dBFS in the tone and channel identifier source modes.
Firmware Update The DAT-100 firmware can be updated in the field through the USB port. Firmware and the required host update software is available at http://uslinc.com/ftp/DAT100/ . Firmware updates are done using a terminal emulation program to send a ASCII text to the DAT-100. A “virtual communications port” is set up to direct terminal communications to the DAT-100 through USB. A driver for this “VCP” needs to be installed. Drivers for various operating systems are available.
