This article explains how to configure Extron DSP control within Space CE using Innomesh Block IDs and channel IDs. This approach simplifies configuration by eliminating the need for extensive Extron Object ID knowledge.
Block ID Mapping
Innomesh provides several Block ID groupings that correspond to Extron Object IDs.
| Innomesh Block ID | Extron Object ID (First 3 digits) |
|---|---|
| post matrix | 500 |
| input | 500 |
| virtual return / virt ret | 501 |
| microphone / mic | 400 |
| expansion | 502 |
| group | N/A |
group as the Block ID and the Extron Group’s Object ID as the channel ID.Examples
The following examples demonstrate how to map Extron Object IDs to Innomesh equivalents.
- Mic Input Gain 1 (Object ID 40000): Block ID =
mic, Channel ID =1 - Mic Input Gain 2 (Object ID 40001): Block ID =
mic, Channel ID =2 - Virtual Return M (Object ID 50112): Block ID =
virt ret, Channel ID =13
Addressing a Fader
Three points apply when configuring a Space CE audio channel against an Extron DSP.
group is the correct Block ID for almost all configurations. A group already addresses whatever the DSP programmer bundled together, which is normally the level a user should be given. The mic, input, virtual return, and expansion blocks address a single gain block that has no group of its own, and are rarely required.
Level and Mute are addressed separately and typically use different channels. Each has its own Device ID, Block ID, and Channel ID. Common pairings are group 3 for level with group 4 for mute, and group 1 with group 2. Both orders occur, so take the numbers from the DSP file rather than assuming a pattern.
Minimum and Maximum are in whole decibels. The driver converts to Extron’s tenths of a decibel on the wire. Typical ranges are -50 to 0, -50 to 12, and -100 to 0. Do not enter tenths here.
Protocol Reference
Refer to Extron’s protocol documentation for detailed gain block assignments and their corresponding Object IDs when mapping additional channels.
