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

Parameter	Value
Protocol	HowlNET over RJ45
Maximum Cable Length	100m (328 ft) per system
Maximum Nodes	32

Cable Requirements

Recommended Cables:

Cable Type	Maximum Length	Notes
Cat5e / Cat6	100m (328 ft)	Shielded 24AWG

warning

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

DC Power Port

Connector: 5.5mm x 2.5mm barrel jack

Parameter	Value
Voltage	24V DC
Current	2.5A maximum
Polarity	Center 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

Box Buttons

Button	Function
Wake	Activate camera auto-focus
Trigger	Activate Effect (trigger cameras)

Button Behavior

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