SYNC Trigger Button Circuit

The SYNC connector has a 3.3 V Schmitt trigger (5 V tolerant). The trigger is not a switch closure circuit, so it requires that the trigger source supplies current. Both edges of the input signal may be used as a trigger.

NOTE: The SYNC trigger button circuit only applies to the DSMC2 Base Expander.

For example, this is the behavior of the circuit when the GPI trigger is used for record start/stop:

  • Start Record: On ground to 3.3 V transition
  • During Record: Hold at 3.3 V
  • Stop Record: On 3.3 V to ground transition
  • During Stop: Hold at ground

Serial (RS232 Control)

The DSMC2 REDVOLT Expander features a SERIAL connector. The 7-Pin 0B SERIAL port connector supports RS232 RX, RS232 TX, and a General Purpose Input (GPI) trigger (active-low switch closure). The connector also offers auxiliary power out, with a maximum sustained current draw of 1.5A.

To operate the GPI contact closure style trigger, short Pin 7 (GPI) to Pin 6 (ground).

The SERIAL connector was designed to support 6-pin 0B cables used with the RED Tactical Hand Controller (T.H.C.). Although the connectors on those cables do not have pin 7 (GPI), the other 6 pins do match pins 1 to 6 on the SERIAL connector.
