Camera Interfaces

Connect external trigger, clock, and output signals using the correct port and cable for your DELTA camera.

DELTA-01 rear ports

Use an SMA cable to connect an external trigger to the right-hand rear port, viewed from behind the camera as shown below.

Do not use the left port Connecting to the left-hand port causes the camera to turn off. Use only the right-hand port for external trigger input.

DELTA-01 rear view: the left SMA port is marked Do Not Use; the right SMA port is Trigger in

Trigger input signal

Use the following signal-generator settings for the external trigger input.

Setting	Value
Amplitude	1.8 V peak-to-peak
Offset	0.9 V
Frequency	Set to the required trigger rate
Duty cycle	50%
Waveform	Square wave

These settings produce a signal that switches between 0 V and 1.8 V.

DELTA-10 M8 connector

DELTA-10 uses a 6-pin M8 connector. Use a matching cable with the pin assignment shown below. The diagram shows the connector on the camera, viewed from the rear; match the numbered pins rather than assuming the cable-side view is the same.

DELTA-10 rear M8 connector: pin 2 is Trigger in, pin 4 is Trigger out, and pin 5 is External Clock

Pin	Signal	Direction at the camera
2	Trigger In	Input
4	Trigger Out	Output
5	External Clock In	Input

Input and output signals

Trigger In and External Clock In use the following input signal. Set the trigger frequency to the required capture rate; set the external clock frequency to the reference clock expected by the camera configuration.

Setting	Trigger In / External Clock In
Amplitude	1.8 V peak-to-peak
Offset	0.9 V
Frequency	Match the trigger rate or configured reference clock
Duty cycle	50%
Waveform	Square wave

Trigger Out Trigger Out sends short 0–1.8 V pulses at the selected sensor timing.

NRV cable wire colors

This genuine NRV cable is for DELTA-10 only. Use the diagram and table below to identify its wires.

NRV M8 cable: pin 1 blue, pin 2 green and brown striped for Trigger In, pin 3 green, pin 4 orange and brown striped for Trigger Out, pin 5 blue and brown striped for External Clock, and pin 6 orange — Genuine NRV cable for the DELTA-10 M8 connector.

Pin	NRV cable wire color	Signal
1	Blue	—
2	Green / brown striped	Trigger In
3	Green	—
4	Orange / brown striped	Trigger Out
5	Blue / brown striped	External Clock In
6	Orange	—

The supplied diagrams do not specify signal functions for pins 1, 3, and 6.
