Network Setup: IP Control & Management

Network Setup: IP Control & Management

Overview

The FLEX Matrix is managed via a built-in web GUI and supports RS-232, TCP/IP, and UDP control for third-party integration with Crestron, AMX, Savant, Control4, and scheduling systems. This article covers network configuration, the web GUI, and the control API.

IP Configuration

The FLEX chassis defaults to DHCP. For production installs, assign a static IP.

  1. Connect the chassis management Ethernet port to the network switch.
  2. Find the assigned DHCP address on the front panel display or via DHCP lease table.
  3. Open the web GUI in a browser. Navigate to System → Network.
  4. Switch to Static IP. Enter the IP address, subnet mask, gateway, and DNS.
  5. Save and reconnect to the new static address.

Recommended: Place the FLEX chassis on a dedicated AV management VLAN separate from display and source traffic.

Web GUI

The web GUI provides full system control without any software installation:

  • Routing Matrix: Visual grid — click any intersection to route input to output
  • Video Wall: Create and manage wall zones, assign outputs, set bezel correction
  • Multiview: Configure Quad View, PiP, and PoP per output
  • Output Settings: Per-output resolution, scaling mode, EDID, CEC, PoC
  • Input Settings: Per-input EDID management, HDCP mode
  • Presets: Save and recall named routing configurations
  • System: Firmware update, network config, user management, logs

RS-232 Control

DB9 connector on rear panel. 115200 baud, 8N1, no flow control.

Common commands:

CommandFunction
SET IN x OUT y\rRoute input x to output y
GET ROUTE y\rQuery which input is routed to output y
PRESET SAVE n name\rSave current routing as preset n
PRESET LOAD n\rRecall preset n
SET WALL name SOURCE x\rRoute input x to video wall zone
POWER ON\r / POWER OFF\rSystem power control

TCP/IP Control

Connect via TCP to the chassis IP address on port 23 (Telnet-style). Commands are identical to RS-232. The chassis maintains persistent TCP connections for low-latency control.

UDP Control

Send UDP datagrams to port 5000 for fire-and-forget commands. Useful for simultaneous broadcast commands to multiple chassis on the same network segment.

REST API

The FLEX chassis also supports a REST API for integration with web-based control systems and scheduling software:

  • GET /api/route — Return current routing table
  • POST /api/route — Set routing: {"input": 3, "output": 7}
  • GET /api/presets — List saved presets
  • POST /api/presets/load — Recall a preset by name or ID

Third-Party Control Integration

  • Crestron / AMX: RS-232 or TCP/IP driver. KanexPro provides sample modules — contact support@kanexpro.com
  • Savant / Control4: Generic TCP/IP device using REST API or Telnet command set
  • Scheduling software: REST API or UDP broadcast for time-based preset recall
