Typical Uses

  • Strobe/flash triggers
  • Wireless transmitter triggers (PocketWizard, etc.)
  • External device triggers
  • Relay control
High Voltage Flash

Some vintage flash units have trigger voltages exceeding 200V. These require an isolation adapter or modern wireless trigger to protect the WOLF ONE outputs.

Internal pull-up voltage3.3 V (internal)
Internal pull-upsYes (Tip and Ring)
Idle stateTip and Ring = HIGH
Triggered stateTip or Ring shorted to Sleeve (GND) = LOW
Input driveDry-contact only (do not drive with external voltage)
ProtectionNo overvoltage or reverse-polarity protection. Miswiring may damage the device.

Typical Uses

  • Arc Eye Handheld Controller
  • Foot pedals
  • Wired remote triggers
  • Custom trigger circuits

⚠️ DO NOT CONNECT

  • External voltage sources
  • Audio or headphone outputs
  • TRRS plugs or phone headsets
  • Powered logic signals

This port accepts dry-contact closures only. This is a control input, not an audio jack.

Button Behavior

  • On daisy-chained systems, buttons on any node trigger all nodes

HowlNET Ports (IN/OUT)

Connector: RJ45

Purpose

Daisy-chain multiple WOLF ONE nodes into a synchronized network.

Connection Rules

  • Connect HowlNET OUT of one WOLF to HowlNET IN of the next WOLF
  • First node in the chain is the Director
  • Subsequent nodes nodes are Listeners
  • The Director node connects to USB for computer control

Specifications

ParameterValue
ProtocolHowlNET over RJ45
Maximum Cable Length100m (328 ft) total length
Maximum Nodes32

Cable Requirements

Recommended Cable:

Cable TypeRequired Spec
HowlNet Bus CableShielded 24AWG
Cat5e / Cat6Shielded 24AWG
warning

Do NOT use crossover cables. Do not connect HowlNET ports to standard Ethernet switches or routers. HowlNET uses a proprietary protocol.


DC Power Port

Connector: 5.5mm x 2.5mm barrel jack

ParameterValue
Voltage24V DC
Current2.5A maximum
PolarityCenter positive

Power Distribution

When nodes are daisy-chained via HowlNET, power is distributed through the network:

  • Connect 24V adapter to the first node only
  • Power flows through HowlNET cables to all nodes
  • Each node consumes 1W idle, 1.6W peak, 2W maximum

USB Type-C Port

Connector: USB Type-C

Functions

  1. Power Input: 5V USB power for single-node operation
  2. Configuration: USB communication with Leash app
  3. Firmware Updates: Flash new firmware via Leash app
