CONNECTORS: SMA female connectors - mates nondestructively with other SMA connectors per MIL-C-39012, 3.5mm and other 2.92mm connectors. CONTROL CONNECTOR: The TTL control connector is an AMP-Latch 10 pin ribbon cable connector that mates with AMP P/N 746285-1 (supplied with each unit). The USB is a 5-pin female series B mini socket and mates with most standard USB 5-pin male series B mini plug connectors.

The AUCS will allow the user to setup, control and perform test and measurements using these digital attenuators over a standard USB 2.0 communication interface. 239 5305 Spectrum Drive, Frederick, MD 21703-7362 s TEL: 301-846-9222, 800-638-2048 s Fax: 301-846-9116 web: www.aeroflex.com/weinschel s email: [email protected] Revision Date: 5/7/2015 Programmable Attenuators CONTROL CONFIGURATION: Units are supplied with both parallel-TTL and USB 2.0 interfaces. The mode of operation is determined by the source of DC power to the unit. NOTE: Do not simultaneously connect DC power to the J4 TTL connector while the USB is connected or to the USB while the J4 TTL is connected. energize a cell to the high attenuation state, whereas a TTL low will maintain a cell in its zero attenuation state. USING USB CONFIGURATION: The USB interface is compatible with standard USB 2.0 interfaces. In USB mode, DC power to the attenuator is provided by the host USB connection. The attenuator operates as a USB CDC device and accepts simple ASCII text commands. This allows the unit to be controlled from any system capable of sending data via a standard COM port-style interface. USING TTL CONTROL: Each unit is supplied with a mating 10 pin connector (Amp 746285-1). Refer to Physical Dimensions for mating connector pin/wiring details. Two pins are specified for supply voltage and ground. The remaining pins will accept TTL control signals to activate or de-activate a particular attenuation cell.
