About the Crestron CNTBLOCK
The block brings several Cresnet cables together in one place. Its eight 4-pin connectors are grouped in two sets of four and distribute Cresnet in parallel, so each cable can land on its own connector. It suits an equipment cabinet, a closet or the underside of a table, and it has diagnostic LEDs.
Power can be isolated between the two sets of four by removing an internal jumper. When replacing a CNTBLOCK, check whether the jumper was removed in the existing block, so that the new one is set up the same way, and reconnect each Cresnet cable to the matching connector.

Questions about the Crestron CNTBLOCK
What is the Crestron CNTBLOCK?
It is a Cresnet distribution block: a parallel distribution block for terminating multiple Cresnet cables at one point. It has eight 4-pin connectors in two sets of four and is designed for use in an equipment cabinet, a closet or beneath a table.
How many connectors does the CNTBLOCK have?
It has eight 4-pin connectors, grouped in two sets of four. The block distributes Cresnet in parallel across the connectors, so several Cresnet cables can each be terminated on their own connector.
Can power be separated between the two sets on the CNTBLOCK?
Yes. Power can be isolated between the two sets of four connectors by removing an internal jumper. When replacing a block, check whether the jumper was removed in the existing unit so that the new one is configured the same way.
Where is the block used?
Crestron designed it for terminating multiple Cresnet cables in an equipment cabinet, a closet or beneath a table. It gives one tidy point where several Cresnet runs connect, and it has diagnostic LEDs.
Is the CNTBLOCK the same as a Cresnet hub?
No. The CNTBLOCK is a parallel distribution block for terminating Cresnet cables. The CNXHUB is Crestron's Cresnet hub, with six isolated segments, and Crestron notes that a hub is ordinarily required for any Cresnet network with more than 20 devices or 3000 feet (914 metres) of cable.
How much is the Crestron CNTBLOCK?
Crestron asks its dealers to give the price of the CNTBLOCK directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the CNTBLOCK?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the CNTBLOCK on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the CNTBLOCK come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the CNTBLOCK develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the CNTBLOCK in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the CNTBLOCK without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
