5.5 Force-Record Shunt Installation

The SDR2-USB can be forced into record mode any time power is applied and USB storage is present. To use this mode, install a 2mm shunt between J4 pins 4 (REC_TOGGLE) and pin 2 (GND).

Agood choice of shunt is Norcomp part number 810-002-SP2L001 (Digi- Key part number SP2-001E-ND).
