note
Legacy cable image: this diagram shows the original flying-leads colors used by the 3M & 5M cables. If your cable matches these colors, wire directly from it. If it does not match (10M cable, solid colors plus a Yellow/Green lead on pin 12), see the Wire Color Reference for the 3M & 5M vs 10M cable colors.
I/O Electrical Characteristics
| Parameter | Specification | Notes |
|---|---|---|
| Input Voltage Range | 0-24 VDC | |
| Input Logic | Pull to GND = Active | NPN compatible |
| Output Current | 100 mA maximum | Per output |
| Output Logic | Sinking to GND | When active |
| Output State | Floating | When inactive |
warning
- Digital outputs (DO0 / DO1) are NPN open-collector, sinking only. They pull the line to GND when active and cannot source +24 V. An external pull-up or load to +24 V must be provided for proper operation.
- DIO GND (Pin 7) must be connected to GND for digital input functionality to work
- DIO GND is tied to GND through a thermal fuse
- When connecting to systems with different power supplies, use DIO GND to tie grounds together
- Reset (Pin 15) - Pull to GND to reboot camera (not needed for most applications, keep floating to avoid unexpected restarts)

Pin Assignment Table
The wire colors of the flying-leads Power & I/O cable depend on the cable length. The 3M and 5M cables use striped secondary colors, while the 10M cable uses solid colors and includes an extra lead on pin 12. Identify your cable by its length before wiring.
| Pin | Signal | Wire Color (3M & 5M Cable) | Wire Color (10M Cable) | Function |
|---|---|---|---|---|
| 5 | GND | Pink (PK) | Pink (PK) | Power Ground |
| 6 | GND | Yellow (YE) | Yellow (YE) | Power Ground |
| 7 | DIO GND | Black (BK) | Black (BK) | Digital I/O Ground |
| 8 | DI0 | Gray (GY) | Gray (GY) | Digital Input 0 - NPN Active Low |
| 9 | DI1 | Red (RD) | Red (RD) | Digital Input 1 - NPN Active Low |
| 10 | DO0 | Violet (VT) | Violet (VT) | Digital Output 0 - NPN Sinking |
| 11 | DO1 | Orange (OG) | Orange (OG) | Digital Output 1 - NPN Sinking |
| 12 | Reserved | No lead | Yellow/Green (YEGN) | Not connected internally |
| 13 | Vin+ | Light Blue (LTBU) | Blue (BU) | Power Input Positive (19-24V) |
| 14 | Vin+ | Black/White (BKWH) | White (WH) | Power Input Positive (19-24V) |
| 15 | Reset | Brown/White (BNWH) | Brown (BN) | System Reset - NPN Active Low |
| 16 | Trigger | Red/White (RDWH) | Green (GN) | Trigger Input - NPN Active Low |
| 1,2,3,4,17 | Reserved | - | - | Not connected |
caution
On the 10M cable, the Yellow/Green lead on pin 12 is not a protective earth conductor, and the solid Green lead on pin 16 is the Trigger input. Do not wire by color convention alone. Leave the pin 12 lead unconnected.
Power Connections
Dual Power Input Design:
- Pins 13 and 14 are both Vin+ (19-24V positive) inside the camera
- Pins 5 and 6 are both power GND
- Because each pair is internally common, connecting one pin of each pair is enough to run the camera
- Wiring both pairs doubles the conductor cross-section, which reduces voltage drop on long cable runs
note
If the camera will not boot or browns out under load, connect the 24V supply to both Vin+ pins (13 and 14) and both grounds (5 and 6) rather than a single terminal each. The two ground wires can share the same terminal on your supply or terminal block.
