Application Notes: Dante in Corporate AV Installations
Boardrooms, conference rooms, campuses, lobbies — real-world deployment scenarios Corporate AV is among the most practical deployment target for…
Overview
KanexPro control extenders and expanders add additional I/O ports to the control system — either as a standalone IP-based controller for simple deployments or as a network-attached I/O expansion module for larger systems.
SKUs
| SKU | Title | Key Differentiator |
|---|---|---|
| CR-3XCONTROL | IP-Based IR, RS-232 and Relay Controller with PoE | Standalone 3-in-1 IP controller — IR + RS-232 + relay, no processor required |
| CR-EXPAND1 | PoE Control Expander with Serial, IR, Relay & Digital I/O | Full-featured I/O expander with digital I/O |
| CR-EXPAND4 | 4-Port AV Control Expander — Serial, Relay & Ethernet | 4-port serial expander, rack/surface mount |
CR-3XCONTROL — Standalone IP Controller
A compact PoE device that provides IR, RS-232, and relay control over IP — without requiring a separate control processor. Command it directly via TCP/IP or integrate it as an expander node in a larger system. Ideal for simple one-room deployments or adding control to a single device location on a network.
- I/O: IR out, RS-232, relay
- Control: TCP/IP commands, can operate standalone
- Power: PoE (IEEE 802.3af)
- Use case: Simple room control, single-device IP controller, expander node
CR-EXPAND1 — PoE Control Expander
A full-featured I/O expander that connects to the control processor over IP and adds RS-232, IR, relay, and digital I/O ports at a remote location (near displays, projectors, or equipment racks). PoE-powered, no separate power supply needed.
- I/O: RS-232, IR out, relay, digital I/O
- Power: PoE (IEEE 802.3af)
- Network: 10/100 Ethernet
- Use case: Extend processor I/O to remote device locations
CR-EXPAND4 — 4-Port Serial Expander
A 4-port RS-232/serial expander with relay and Ethernet. Designed for larger rooms or multi-device locations where multiple serial-controlled devices are co-located (equipment rack, AV closet). Can be rack-mounted or surface-mounted.
- I/O: 4× RS-232, relay, Ethernet
- Power: External power supply (included)
- Mounting: Rack mount (1U) or surface mount
- Use case: Multiple serial devices in one location, rack-based AV systems
When to Use Each
- Simple room, no processor needed: CR-3XCONTROL
- Extend processor to remote location, digital I/O needed: CR-EXPAND1
- Multiple serial devices in one rack location: CR-EXPAND4
