Communication Ports

SYNC (Video Sync In) with SYNC Trigger Button Circuit

The DSMC2 Base Expander features a SYNC connector with a SYNC Trigger Button Circuit.

The 4-pin 00B LEMO SYNC connector accepts timecode, genlock, and General Purpose Input (GPI) signals.

Figure: Front Face of the SYNC (Video Sync) Connector (Looking at the Camera)

NOTE: Mating connector is FGG.00.304.CLAD.

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

NOTE: In the diagram above, values are approximate. Use standard values.

The following expanders feature a SYNC connector with contact closure style trigger input:

• DSMC2 Jetpack Expander
• DSMC2 Jetpack-SDI Expander
• DSMC2 V-Lock I/O Expander

The 4-pin 00B LEMO SYNC connector accepts timecode, genlock, and General Purpose Input (GPI) signals. To operate the GPI contact closure style trigger, short Pin 2 (GPI) to Pin 1 (ground).

WARNING: DO NOT apply voltage to Pin 2 (GPI).

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.

• 790-0187: 4-Pin 00 LEMO-to-Flying Lead
• 790-0415: RED Start/Stop Cable (14-Pin LEMO to SYNC, CTRL, BNC)

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.

Compatible Cables

For GPI applications, you can use this cable:

• 790-0553: RED 7-Pin 0B LEMO-to-Flying Lead Serial Port Cable (6')

For non-GPI applications, you can use this 6-pin cable:

• 790-0444: R.C.P.^®-to-T.H.C. Connector Cable 3'

Genlock

The 75 ohm BNC connector accepts incoming sync and genlock signals.

Timecode

The DSMC2 REDVOLT Expander features a Timecode (TC) connector.

The LEMO EAG.0B.305.CLN connector supports SMPTE timecode input and output. Pins 2 and 3 can be used together to receive a balance SMPTE 12M serial timecode input. Pin 2 can be used by itself (leave pin 3 open) to receive a single-ended SMPTE 12M serial timecode input. Pin 5 is a timecode output.

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.
