4-Series Control System for Crestron Home

The Crestron MC4-R is a 4-Series control system built for Crestron Home OS installations. It delivers a 100/1000 Mbps Ethernet link with a full TCP/IP stack, SSL, TLS and SSH, plus a Cresnet server on one port. An infiNET EX 2.4 GHz transceiver provides two-way RF mesh connectivity. Internal memory includes 2 GB SDRAM and 8 GB flash with a microSD slot accepting cards up to 32 GB.

Installers running Crestron Home OS

This unit suits integrators deploying a Crestron Home OS backbone that need wired Ethernet, Cresnet, RS-232, IR and infiNET EX wireless in one chassis. It is not for projects that require a different automation platform or that lack a Crestron Home OS licence. Buyers needing more than 500 BACnet objects or RF range beyond 50 ft to the nearest mesh node should look elsewhere.

infiNET EX 2.4 GHz RF mesh transceiver

The built-in infiNET EX transceiver operates on IEEE 802.15.4 channels 11 through 26 between 2400 and 2483.5 MHz, defaulting to channel 15. It delivers two-way RF communication up to 50 ft to the nearest mesh device, with floor-to-floor reach limited to one level. This single wireless spec determines whether the controller covers the intended installation area.

Questions about this item

How do I connect the MC4-R to the Cresnet bus and what wiring mistake should I avoid?

Wire the Cresnet bus to the dedicated Cresnet port using Crestron Cresnet cable; the common error is reversing the polarity on the four conductors, which prevents the control system from discovering the device.

Which field-replaceable storage does the MC4-R use for log files and what is the maximum supported capacity?

The microSD card slot on the front panel accepts a single microSD card up to 32 GB for log-file storage; swap the card when it reaches capacity or shows read errors.

What is the practical RF range limit of the infiNET EX transceiver before mesh hops become necessary?

The 2.4 GHz infiNET EX radio reaches about 50 ft (15 m) to the nearest mesh node under typical site conditions; beyond that distance you must add powered mesh devices to maintain reliable two-way communication.
