Channels Patched Between Address 257-512 Do Not Output

Symptoms/Issue

Channels patched between DMX addresses 257-512 on local DMX ports will not output from the console. Allowed Output Addresses is not limiting these addresses.

Description/Explanation of Issue

By default, Dimmer Doubling support on local DMX ports reserves DMX addresses 257-512 for the "B-side" of dimmers in a Sensor rack with Dimmer Doubling enabled. This allows you to patch dimmer 1A and 1B as DMX addresses 1 and 257, respectively. However, this means that those addresses will be unavailable when trying to patch them directly.

Fix/Solution

  1. Check the Local DMX Output settings on your console.
    1. On Eos software 2.7.0 and higher, these settings are located under Setup -> System -> Output
    2. On Eos software 2.6.4 and lower, these settings are located in the Shell settings in the Local I/O tab
  2. Make sure that Doubled is unchecked or set to No for the affected ports.
