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

CTRL (RS232 Control)
The following expanders feature a CTRL connector:
- DSMC2 Base Expander
- DSMC2 V-Lock I/O Expander
- DSMC2 Jetpack Expander
- DSMC2 Jetpack-SDI Expander
- DSMC2 REDVOLT Expander
The 4-pin 00B LEMO CTRL connector supports RS232 remote control for 3D camera communication and third-party metadata ingest applications. For more information, go to BRAIN GPIO.
The General Purpose Out (GPO) tally presents 3.3 V at a maximum of 0.04 A between pins 1 and 3. When used as a record tally, the rising edge of the pulse indicates start of record, falling edge represents end of record.
For more information about controlling the camera via RS232, download the R.C.P.™ SDK.

Serial (RS232 Control)
The DSMC2 REDVOLT Expander features a SERIAL connector. The 7-pin 0B LEMO SERIAL 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.

GIG-E (Ethernet)
The following expanders feature a GIG-E connector.
- DSMC2 Jetpack-SDI Expander
- DSMC2 REDVOLT Expander
The GIG-E 9-pin 0B LEMO connector provides a 1000BASE-T (IEEE 802.3ab) gigabit Ethernet connection for remote camera setup, master/slave camera communication, and external metadata ingest. Since the GIG-E connector does not support slower speeds (10BASE-T and 100BASE-T), ensure that any device you connect to supports 1000BASE-T.
