Stewart Filmscreen Corporation eNode Control Spec

Summary

Ethernet-connected lighting and motor controller supporting Telnet (TCP), UDP, and RS-232c. Controls LED lighting and motorized screen systems via Z.G.N addressing scheme. Supports bi-directional feedback via NOTIFY system.

Transport

protocols:
  - tcp
  - udp
  - serial
addressing:
  port: 23  # Telnet port stated
  udp_ports: [4000, 5000]
serial:
  # UNRESOLVED: RS-232c via IBT-100 adapter - baud rate, data bits, parity, stop bits not stated in source
  # IBT-100 is external adapter; serial params defined by adapter, not eNode
auth:
  type: configurable  # Login can be ENABLE or DISABLE via e-Node Pilot; inferred from "with or without authentication"

Traits

# Inferred from command tables:
- powerable       # ON/OFF commands present (LED table, Motor table)
- routable        # GOTO command present for motor positioning
- queryable       # COLOR=?, VALUE=?, POSITION=? bi-directional queries present
- levelable       # FADE_UP, FADE_DOWN, CCT, CCT_UP, CCT_DOWN, brightness control present

Safety

confirmation_required_for: []
interlocks:
  - CS-Bus must maintain twisted pairs on pins 1&2, 3&4, 5&6
  - Do NOT use telephony cable (wiring topology swapped: 1-6, 2-5, 3-4)
  - Do NOT use standard Ethernet cabling (568A or 568B) - twisted pairs inconsistent with CS-BUS
  - Bus must be terminated at beginning and end with 120 ohm resistor on pins 3/4
  - DMX bus must be terminated on final OUT/THRU connector with 120 ohm resistor
  # UNRESOLVED: specific interlock procedures for motor retraction/extension safety not detailed

Notes

Command Syntax: #Z.G.N.COMMAND=VALUE<cr> — Zone.Group.Node addressing with wildcard support (0 broadcasts to all matching)

Bi-directional Feedback: Response format !Z.G.N.COMMAND=VALUE — exclamation mark indicates message from CS-Bus device

Addressing:

• Zone: 1–254, Group: 1–254, Node: 1–254
• Wildcard "0" broadcasts to all matching controllers

DMX Configuration:

• Maximum 32 fixtures per e-Node/dmx
• Maximum 4000 feet CS-Bus cabling (CAT5e or better)
• Maximum 254 controllers per e-Node
• DMX maximum cabling: 1200 meters (3900 feet)

CS-BUS Wiring: RJ-25 / RJ-11 6P6C standard; must maintain twisted pairs; 120 ohm termination required

Telnet Authentication: Default credentials Telnet 1/Password 1 (format: first letter cap, space before number); can be disabled via e-Node Pilot
