Discover and IP

Use IDFM to find Innosonix amplifiers (UDP discovery or add/scan), then set STATIC-IP or DHCP, hostname, and identify the physical unit.

Goal / when to use

Put every amplifier on the site IP plan: discover (or add) devices, set STATIC-IP or DHCP, name them, and confirm which physical unit is which.

Prerequisites

  • IDFM installed with healthy UDP STATUS when you expect automatic discovery
  • PC on the same L2 segment as the amps for UDP broadcast, or known amp IPs / reachable routed subnet for add/scan

UDP discovery (preferred)

On the same switch / VLAN, IDFM discovers amps with UDP broadcast on port 9453 (255.255.255.255).

  1. Open DEVICES.
  2. Wait for rows to appear (hostname, model, firmware, IP, status).
  3. Filter or sort the table if you have many units.

UDP discovery still works when the amp’s configured IP is on a different subnet than the PC — as long as they share the same broadcast domain. That is how you recover “wrong IP” units without serial console access.

Example (wrong subnet, same switch)

PC:         192.168.0.33 / 255.255.255.0
Amplifier:  192.168.99.2 / 255.255.255.0

Unicast HTTP may fail, but UDP discovery can still list the amp and accept a new IP configuration.

Expected result

Amps show as online in the list. You can open IP / hostname dialogs from the row.

Set IP (STATIC or DHCP)

  1. Click the IP cell for the device.
  2. Choose TYPE:
    • STATIC-IP — enter IP, subnet, gateway
    • DHCP — device takes an address from the DHCP server
  3. Click SET.
  4. Optional on DHCP: NEW DHCP LEASE to renew.

After a STATIC change, wait a few seconds for the list to refresh. After DHCP, the old address may go offline until the amp reappears with the new lease.

Hostname and identify

ActionHow
HostnameClick the hostname cell → enter a unique name → SET HOSTNAME
IdentifyUse IDENT on the row so the physical amp signals which unit you selected
LocationOptional site text via the location cell (stored on the device when reachable over HTTP)
Device pageUse the external/page control to open the amp’s web UI (Maxx Control) once the IP is reachable

Add by IP or subnet scan (routed networks)

Routers do not forward UDP broadcast. If the PC and amps are on different routed VLANs, use + above the device list:

  1. Add by IP — enter a known amplifier IP (device must answer ping / HTTP).
  2. Subnet scan — enter the first three octets of the target /24 (for example 192.168.99) and scan. IDFM probes live hosts via the device HTTP REST API.

Example (routed VLANs)

VLAN1: PC          192.168.0.33 / 24
         |
       ROUTER
         |
VLAN2: Amplifier   192.168.99.2 / 24

Scan or add in 192.168.99.0–255. After add, configure IP/hostname as needed (unicast path must reach the amp).

Expected result

Added devices appear in the list (often marked as manually added). Save the list if you want them remembered on next launch.

List tools

On DEVICES you can save, clear, or export the current device list. Saving helps when you rely on manually added units across sessions.
