5.3 Functions

Table 5.1 describes the functions of the J4 remote connector.

VDD (3.3VDC)

GND (0 VDC)

REC_BUTTON

REC_TOGGLE

FAULT

DATA

RECORD

Regulated low-current voltage output. Use for deasserting active-low inputs and driving LED indicator outputs.

Signal ground. Use for asserting active-low inputs.

Momentary record input. Function is similar to front-panel record button. To use, connect a momentary pushbutton switch between this contact and GND.

Force-record input. To use, connect a toggle switch between this contact and GND. When closed, the SDR2-USB will always enter record mode.

Fault condition indicator output. Function is similar to the front-panel Fault indicator. When low, indicates an unrecoverable error has occurred in the SDR2-USB. To use, connect an LED’s cathode to this contact and its anode to VDD via a current-limiting resistor. Limit current to 10 mA max.

Data indicator output. Function is similar to the front-panel Data indicator. Pulses momentarily low to indicate data reception in the SDR2-USB. To use, connect an LED’s cathode to this contact and its anode to VDD via a current- limiting resistor. Limit current to 10 mA max.

Recording indicator output. Function is similar to the front- panel Record indicator. Driven low when the SDR2-USB is recording data to an open file. To use, connect an LED’s cathode to this contact and its anode to VDD via a current- limiting resistor. Limit current to 10 mA max.

5.4 Pinout and Mating Cable

The J4 connector is a 2mm 10-pin connector housing that mates to a Hirose DF11-10DS-2C shell (Digi-Key part number H2023-ND). A pre-built J4 cable is available from Acumen Instruments Corporation on request.
