Harness wire assignment

Kirra can model electronic initiation products that use surface / harness wire (initiator type SurfaceWire in the product database). The Harness Wire Assignment tool lets you give each chain of holes a path / channel number, a commander (or equivalent firing-unit) number, a channel colour and a primer order. Field labels adapt to the electronic system named on your harness wire product.

Prerequisites

  1. Product database — Load products that include a SurfaceWire product linked to an electronic system. Without one, the dialog falls back to generic labels (Channel and Commander).
  2. Chain anchor holes — The tool only works on self-connected holes: the hole a surface-wire or connector chain starts from. If you click any other hole, Kirra shows the warning “Select a self-connected hole (chain anchor)”.

Using the tool

  1. Click Harness Wire Assignment (Channel / Commander) in the Connect toolbar.
  2. Click a self-connected hole in 2D or 3D. In 2D you can also click the first vertex of a trunk; Kirra uses the first hole on that trunk’s chain.
  3. The Harness Wire Assignment dialog shows the hole ID and the electronic system, with these fields:
    • Path / channel — a number, or a letter (A, B, C …) for systems that identify paths by letter. The label comes from the system (for example Channel #).
    • Commander # (or the system’s firing-unit term) — shown when the system has a firing unit.
    • Channel Colour — the colour used to draw that channel.
    • Primer Order — Top to Bottom or Bottom to Top: the order detonators are numbered along the harness.
  4. Click Assign. Kirra stores the values on the hole and checks them against the system’s limits; any problems are shown as a validation warning.
