Netron EN RS-232 / IP control commands

Summary

Netron EN and EN-12 are EtherDMX gateways that bridge Ethernet-based lighting control protocols (Art-Net and sACN) to DMX512 output. Up to 12 DMX ports on the EN12 model with RDM, merging, cloning, and preset recall capabilities. The device is configured via a web browser interface at its IP address and onboard display menus; remote triggers are issued as DMX/Art-Net/sACN values at a configured Universe/Address.

Events

# UNRESOLVED: no unsolicited notification protocol documented

Macros

# Cue recall (1-99) via Remote Input trigger
# Netron Preset recall (a, b, c, …) via Remote Input trigger
# User Preset recall (1-10) via Remote Input trigger
# Disable DMX via Remote Input trigger
# Send static DMX value (0-255) via Remote Input trigger
# Signal Loss sequence: Hold Last Look → timeout → {Fade to 0 | Cue | Disable DMX}
# Startup sequence: {Cue | Wait for Data | Send 0}

Safety

confirmation_required_for:
  - factory_reset_full
  - factory_reset_user_preset
interlocks:
  - "Do not power cycle during firmware update (Display NFW or Web IMG)"
# UNRESOLVED: no other safety-critical commands or interlock procedures stated in source

Notes

Device configured entirely via onboard display menus and web browser UI — no discrete serial command protocol exists.
Up to 10 Netron devices can be daisy-chained via Ethernet; exceeding 10 in one chain is not recommended.
Default IP mode: factory-assigned unique 2.x.x.x address (subnet 255.0.0.0). Auto modes also for 10.x, 192.x, 172.x; DHCP supported. EP4 (no display) defaults to 2.0.0.1.
If DHCP fails for 30s, device auto-assigns a 169.254.x.x address but continues monitoring DHCP.
RDM not supported on sACN; supported on Art-Net.
DMX output connectors: EN12 uses 5-pin female XLR (pin 1 Com, pin 2 Data−, pin 3 Data+; pins 4/5 unused — ESTA compliant); EN12-45 uses RJ45 (pin 1 Data+, pin 2 Data−, pins 7/8 Com, shield Earth).
Device lock PIN default is 011; full factory reset PIN is 011; user-preset reset PIN is 007.
Firmware update requires two files (Display NFW + Web IMG) uploaded via System > Maintenance web interface; do not power cycle during update.
Recovery update URL: http://{device_ip}/update.html (used when System menu is corrupt).
Owner Preset lock accessed via hidden URL http://{device_ip}/Preset_Owner.htm — not part of main web UI.
DMX port status LEDs: Red solid = error; Green solid = DMX In, Green blink = DMX Lost; Blue solid = DMX Out Stable, Blue blink = DMX Lost; White flashing = RDM packets.
Source references EN4/EP4 models in some menus; this spec covers EN and EN-12 only.

Spec upgraded. Added: 16 actions (DMX trigger + 5 remote assignments + owner-preset lock + lock/unlock + save/load config + RDM enable/disable + 2 factory resets + 2 firmware uploads + recovery update), 30+ variables (per-port DMX, per-slot remote, IP, system, signal-loss), LED feedback enum, safety confirmations. Bumped revision 1→2, fixed transport tcp→http+udp.

Events

# UNRESOLVED: no unsolicited notification protocol documented

Macros

# Cue recall (1-99) via Remote Input trigger
# Netron Preset recall (a, b, c, …) via Remote Input trigger
# User Preset recall (1-10) via Remote Input trigger
# Disable DMX via Remote Input trigger
# Send static DMX value (0-255) via Remote Input trigger
# Signal Loss sequence: Hold Last Look → timeout → {Fade to 0 | Cue | Disable DMX}
# Startup sequence: {Cue | Wait for Data | Send 0}

Safety

confirmation_required_for:
  - factory_reset_full
  - factory_reset_user_preset
interlocks:
  - "Do not power cycle during firmware update (Display NFW or Web IMG)"
# UNRESOLVED: no other safety-critical commands or interlock procedures stated in source

Notes

Device configured entirely via onboard display menus and web browser UI — no discrete serial command protocol exists.
Up to 10 Netron devices can be daisy-chained via Ethernet; exceeding 10 in one chain is not recommended.
Default IP mode: factory-assigned unique 2.x.x.x address (subnet 255.0.0.0). Auto modes also for 10.x, 192.x, 172.x; DHCP supported. EP4 (no display) defaults to 2.0.0.1.
If DHCP fails for 30s, device auto-assigns a 169.254.x.x address but continues monitoring DHCP.
RDM not supported on sACN; supported on Art-Net.
DMX output connectors: EN12 uses 5-pin female XLR (pin 1 Com, pin 2 Data−, pin 3 Data+; pins 4/5 unused — ESTA compliant); EN12-45 uses RJ45 (pin 1 Data+, pin 2 Data−, pins 7/8 Com, shield Earth).
Device lock PIN default is 011; full factory reset PIN is 011; user-preset reset PIN is 007.
Firmware update requires two files (Display NFW + Web IMG) uploaded via System > Maintenance web interface; do not power cycle during update.
Recovery update URL: http://{device_ip}/update.html (used when System menu is corrupt).
Owner Preset lock accessed via hidden URL http://{device_ip}/Preset_Owner.htm — not part of main web UI.
DMX port status LEDs: Red solid = error; Green solid = DMX In, Green blink = DMX Lost; Blue solid = DMX Out Stable, Blue blink = DMX Lost; White flashing = RDM packets.
Source references EN4/EP4 models in some menus; this spec covers EN and EN-12 only.

Spec upgraded. Added: 16 actions (DMX trigger + 5 remote assignments + owner-preset lock + lock/unlock + save/load config + RDM enable/disable + 2 factory resets + 2 firmware uploads + recovery update), 30+ variables (per-port DMX, per-slot remote, IP, system, signal-loss), LED feedback enum, safety confirmations. Bumped revision 1→2, fixed transport tcp→http+udp.
